Abstract
Background: Food-induced anaphylaxis (FIA) is a serious and potentially life-threatening allergic reaction triggered by food allergens. Objective: This case-control study aimed to investigate comorbidities and laboratory factors associated with FIA in the pediatric population of Israel. Methods: Retrospective data from the electronic health records of Leumit Health Care Services were used to identify 711 pediatric patients with FIA and 2560 subjects with food allergy and without anaphylaxis matched for age, gender, and ethnicity. Comorbidities were identified based on medical billing diagnosis codes, and laboratory characteristics were compared between the two groups. Results: The mean ± standard deviation age of patients with FIA was 4.1 ± 4.1 years, and 37.3% were girls. Laboratory analysis revealed increased eosinophil counts (p < 0.001), elevated immunoglobulin E (IgE) (p < 0.001), and IgA levels (p = 0.001) in the FIA group compared with the controls. With regard to comorbidities, the FIA group had higher prevalence rates of allergic diseases, including allergic rhinitis (odds ratio [OR] 1.72; p < 0.001), allergic conjunctivitis (OR 1.84; p = 0.001), asthma (OR 1.36; p < 0.001), angioedema (OR 6.37; p < 0.001), atopic dermatitis (OR 1.77; p < 0.001), and contact dermatitis (OR 1.42; p = 0.001). There was a trend toward significance for chronic spontaneous urticaria (p = 0.051). There was a significant negative association between helminthiases, particularly enterobiasis, and FIA (OR 0.76 [95% confidence interval, 0.59-0.98]; p = 0.029). Conclusion: This study provides valuable epidemiologic evidence on the associations among FIA, comorbidities, and laboratory factors in the pediatric population.

Abstract
Enterobius vermicularis, an intestinal helminth, is transmitted through the ingestion of eggs found in food, water, dust, or other fomites, including infected individuals. This review aimed to examine the frequency and distribution of E. vermicularis infections in Brazil between 1991 and 2022. The conducted bibliographic survey revealed that the frequency of E. vermicularis infections in Brazil ranged from 0.1 to 26.1%, depending on factors such as population ethnicity, individual age group, geographic area, time frame, and diagnostic method. However, these findings were based on a limited number of publications, suggesting that the actual prevalence rates of E. vermicularis infection may still be unknown and potentially underestimated.

Abstract
Intestinal parasites include intestinal protozoa and intestinal helminths. Intestinal parasitic infections (IPIs) pose a global health problem affecting over one billion people worldwide. Although these infections are predominantly seen in the developing world, they are frequently seen in the developed countries, particularly in immunocompromised patients. Patients' clinical presentations generally include diarrhea, dysentery, abdominal pain, nausea, vomiting, nutritional deficiency, iron deficiency anemia, anal and perianal itching, and rarely intestinal obstruction. The intestinal parasites have similarities in their mode of transmission and life cycle. The stool test is the primary way of diagnosing IPIs. Treatment is given with various anti-parasitic agents. However, appropriate preventive measures are essential for successfully controlling the IPIs.

Abstract
Parasites have affected and coevolved with humans and animals throughout history. Evidence of ancient parasitic infections, particularly, reside in archeological remains originating from different sources dating to various periods of times. The study of ancient parasites preserved in archaeological remains is known as paleoparasitology, and it initially intended to interpret migration, evolution, and dispersion patterns of ancient parasites, along with their hosts. Recently, paleoparasitology has been used to better understand dietary habits and lifestyles of ancient human societies. Paleoparasitology is increasingly being recognized as an interdisciplinary field within paleopathology that integrates areas such as palynology, archaeobotany, and zooarchaeology. Paleoparasitology also incorporates techniques such as microscopy, immunoassays, PCR, targeted sequencing, and more recently, high-throughput sequencing or shotgun metagenomics to understand ancient parasitic infections and thus interpret migration and evolution patterns, as well as dietary habits and lifestyles. The present review covers the original theories developed in the field of paleoparasitology, as well as the biology of some parasites identified in pre-Columbian cultures. Conclusions, as well as assumptions made during the discovery of the parasites in ancient samples, and how their identification may aid in better understanding part of human history, ancient diet, and lifestyles are discussed.

Abstract
Urethritis is mainly caused by sexually transmitted pathogens, such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) [1]. Close to 90 million adults are infected annually with NG [2]. Treatment shall be performed according to national guidelines and resistance profiles [2, 3]. Enterobius vermicularis (EV) is the most common helminth in humans with 1 billion people globally infected [4-6]. Symptoms include anal pruritus; however, many infections are asymptomatic [4-7]. A case of urethritis due to simultaneous infection with NG and EV is reported.

Abstract
Human infection with Enterobius vermicularis occurs worldwide, particularly in children. The role of E. vermicularis in appendicitis is neglected. This study was designed to investigate genotypes of E. vermicularis detected from appendectomy specimens in the human population from Iran and clarify the intra-species variation of the parasite. Seventy appendectomies for acute clinical appendicitis isolates from Azerbaijan and North Khorasan of Iran were used in the present study. The genetic information of Tehran and Hamedan regions was also obtained from GenBank for comparison and analysis. The nucleotide sequence of cytochrome c oxidase subunit 1 (cox1) gene was analyzed to perform genetic differentiation, haplotype network analysis, and population structure. Phylogenetic analysis of all the isolates were included in type B haplogroup. The number of haplotypes in all geographical locations of Iran is not much. Network analysis of sequences for regions such as Thailand, Iran, Denmark, and Poland show three classified subtypes B1, B2, and B3 in the B haplogroup. It seems that the haplotypes of E. vermicularis detected from appendectomy are B type, and divided into three subtypes. Further research using another genetic marker is required to elucidate the genetic variation of the parasites in detail.

Abstract
Enterobius vermicularis is a prevalent intestinal nematode. The objective of the research was to study enterobiasis prevalence in symptomatic children <15 years of age attending community health center in North - Western part of Slovenia in years 2017 - 2022. Perianal tape tests were performed on three consecutive days. The overall prevalence was 34.2 % (296 out of 864 children included). The mean age of children positive for E. vermicularis was 5.77 (95 % CI: 5.51 - 6.04) and 4.74 (95 % CI: 4.54 - 4.95), p<0.001 for children with negative test results. The positivity rate was not significantly different for boys compared to girls (boys 37.0 %, 95 % CI: 32.4 % - 41.8 %, girls 31.8 %, 95 % CI: 27.6 % - 36.2 %, p=0.107). The number of boys with all three samples positive in a sample set was higher compared to girls (p - value 0.002). Family size affected the positivity rate - the mean number of siblings was higher in positive children. Significant association with E. vermicularis infection was proven by the presence of anal pruritus and absence of abdominal discomfort. High E. vermicularis warrants careful monitoring of trends and public health response. It is necessary to encourage the use of hygiene measures in schools and empower parents to recognize enterobiasis timely.

Abstract
Enterobius vermicularis usually causes trivial infections in the juvenile population. However, its extragenital presentation in adults is relatively rare. We present the case of a 64-year-old female suffering from poorly controlled diabetes and lower abdominal pain. CT scan showed a large tumorous expansion of the lower abdomen, mimicking malignancy. Perioperative findings revealed a large adnexal tumor adhering to the rectum. In addition, the histological examination uncovered a mixed inflammatory infiltrate with multiple surrounding eggs of the parasite and granulomatous reaction in the left fallopian tube and left ovarian cortex. As reported in our article, the rare ectopic sites of Enterobius vermicularis in postmenopause may become a diagnostic challenge.

Abstract
Enterobiasis continues to be among the highest parasitic infections affecting the human population worldwide. A study was conducted between 2011 - 2015 in Iraq to evaluate the enterobiasis reported by the Communicable Diseases Control Center (n=220,607 cases) in relation to demographic (age, sex, rural population and family size) and spatial variables (local and regional sources). Females were more parasitized than males, as well as children and youth ages 4 to 15. Approximately 40 % of cases are from the South region provinces (Thiqar, Miasan, Basrah and Wassit). However, most cases occurred in regions with high rural populations and a high family size average. The results may provide insights for researchers assessing management approaches to control enterobiasis in Iraq.

Abstract
BACKGROUND Enterobius vermicularis (E. vermicularis) is a nematode that infects up to 200 million people worldwide, despite effective medications being available. Conventional diagnostic tests are hindered by low sensitivity and poor patient compliance. Furthermore, no biomolecular techniques are available for clinical application. The aim of this study was to develop a procedure specifically designed for clinical application to detect E. vermicularis by means of PCR. MATERIALS AND METHODS Two subject groups were taken into account: a group of 27 infected patients and a control group of 27 healthy subjects. A nested-PCR was performed on fecal samples to detect E. vermicularis. Due to the intrinsic difficulties of the fecal matrix, several countermeasures were adopted to ensure the efficient performance of the method: (a) a large amount of feces for the extraction process (20 g instead of 200 mg); (b) a combination of chemical and physical treatments to grind the fecal matrix; (c) an additional purification process for the negative samples after the first nested-PCR; and (d) the selection of a very specific target region for the PCR. RESULTS Due to the lack of overlap with other organisms, a sequence of the 5S ribosomal DNA (rDNA) spacer region including the tract SL1 was chosen to design appropriate external and internal primers. The first nested-PCR detected E.vermicularis in 19/27 samples from infected patients. After further purification, 5/8 of the negative samples resulted positive at the second PCR. Conversely, all the samples from healthy controls resulted negative to both PCRs. Sensitivity and specificity of the method were, respectively, 88.9% and 100%. CONCLUSION The results prove the high diagnostic accuracy of the proposed method, addressing and overcoming the challenges posed by both conventional tests and PCR-based approaches. Therefore, the method can be proposed for clinical application.

Abstract
Intestinal parasitic infections are common infectious diseases causing many health problems and impaired growth and physical development.. Children under five years old are the most vulnerable to infections, due to their immature immunity and feeding and exploratory behaviours. This systematic review aimed to assess the relationship between intestinal parasitic infections and undernutrition among children under 5 years old. Fifteen studies met the inclusion and exclusion criteria and were classified as high-quality studies. Twelve parasites were reported, including Ascaris lumbricoides, Cryptosporodium spp., Entamoeba histolytica, Enterobius vermicularis, Giardia lamblia, hookworm, Hymenolepis nana, Strongyloides sterocalis, Taenia spp. and Trichuris trichuria. Ascariasis is the most reported infection, with a prevalence ranging from 10.77% in Ethiopia to 57.14% in Malaysia, and is correlated with stunting (OR 2.17 (95% CI 1.14, 4.13), p = 0.02). Giardiasis is the second most reported infection, with a prevalence ranging from 4.43% in Ethiopia to 66.33% in the Central African Republic, and is related to an increased risk of stunting (OR 2.34 (95% CI 1.07, 5.10), p = 0.03)), wasting (OR 2.90 (95% CI 1.12, 7.49, p = 0.03)), and being underweight (OR 1.53 (95% CI 1.02, 2.29, p = 0.04)). The third and fourth most prevalent infections are T. trichiura and hookworm infections. Intestinal parasitic infections can occur very early in life and cause significant growth retardation. It is important to understand the prevalence and effects of infection based on the parasite species in order to implement therapeutic interventions and prevention controls.

Abstract
Enterobiasis is a highly infectious parasitic disease spreading worldwide including Yemen. Therefore, this study aimed to investigate the prevalence and risk factors of enterobiasis among Yemeni children in Dhamar governorate. A total of 402 children (aged 1-12 years) participated in this cross-sectional survey carried out at Thamar University Al-Wahdah Teaching Hospital (TUWTH), between 2018 and 2019. Enterobius vermicularis infection was examined using the adhesive tape technique. Association between risk factors and enterobiasis were measured by prevalence ratio (PR). The overall prevalence of enterobiasis was found to be 29.4% (118/402). Risk factors that showed independent association with the infection were child's care responsibility (PR = 1.90; 95% CI = 1.37-2.63; P = 0.001); irregular washing hands before meals (PR = 2.01; 95% CI = 1.32-3.05; P = 0.003); habit of nail biting or cutting by teeth (PR = 1.61; 95% CI = 1.18-2.21; P = 0.002); habit of putting toys or pen in mouth (PR = 1.58; 95% CI = 1.19-2.10; P = 0.002); frequent anal itching (PR = 1.46; 95% CI = 1.10-1.93; P = 0.016); using anthelmintic during the last six months (PR = 1.68; 95% CI = 1.20-2.36; P = 0.011); and parents have no knowledge on preventive measures (PR = 1.62; 95% CI = 1.04-2.53; P = 0.036). Prevalence of enterobiasis among Yemeni children in Dhamar governorate is high with higher infection rate among those aged 1-6 years. Health education and mass treatment are highly recommended among this poor population.

Characterization of antigens of Enterobius vermicularis (pinworm) eggs. Sci Rep 2022; 12:14414. [PMID: 36002555 PMCID: PMC9402560 DOI: 10.1038/s41598-022-18303-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 08/09/2022] [Indexed: 11/08/2022] Open
Abstract
Enterobiasis (pinworm infection) caused by Enterobius vermicularis is a common parasitic infection prevalent worldwide especially in children. Infection is diagnosed by microscopic detection of E. vermicularis eggs on perianal swabs. This study aimed to characterize the antigens of E. vermicularis eggs as a preliminary step towards identifying diagnostic targets for detection in infected individuals. The study was conducted between October 2019 and February 2020, following approval from Ethics Review Committee of the Faculty of Medicine, University of Colombo (EC-19-034). E. vermicularis eggs were harvested from perianal swabs using acetone and purified with 1× PBS (pH 7.2). A portion of eggs was used for preparing antigen slides, while the rest were sonicated and vortexed with glass beads and inoculated subcutaneously (with weekly booster doses) into a Wistar rat for developing antibodies. Blood drawing from rat was done weekly for 5 weeks. Confirmation of the presence of antibodies was done by surface immunofluorescence against eggs on the antigen slides. Protein bands were determined using SDS-PAGE assay and immunogenic antigen bands were determined by reacting with antiserum after immunoblotting. The band sizes of the proteins were determined against corresponding bands of a protein ladder. Surface immunofluorescence was positive with serum obtained from day 14 post-inoculation from the Wistar rat as well as that obtained from a person with chronic enterobiasis. The most prominent and immunogenic protein bands identified from egg antigens were 21 kDa, 66 kDa, 83 kDa, 96 kDa, 112 kDa, 121 kDa, 140 kDa and 151 kDa. Methods used in this study were effective in obtaining E. vermicularis egg antigens which were immunogenic. Furthermore, surface antigens of intact eggs reacted with antibodies developed against crushed egg antigens. These findings may pave the way for the development of effective immunodiagnostics.

Assessment of the nail contamination with soil-transmitted helminths in schoolchildren in Jimma Town, Ethiopia. PLoS One 2022; 17:e0268792. [PMID: 35767573 PMCID: PMC9242460 DOI: 10.1371/journal.pone.0268792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 05/08/2022] [Indexed: 11/19/2022] Open
Abstract
Background
Large-scale deworming programs have been successful in reducing the burden of disease due to soil-transmitted helminth (STH; Ascaris lumbricloides, Trichuris trichiura and hookworm) infections, but re-infection in absence of other measures is unavoidable. We assessed the role of nail contamination as a source of infection with the goal to evaluate the potential of nail clipping as a simple measure to further reduce STH-attributable morbidity.
Methods
A cross-sectional study was conducted in Jimma Town (Ethiopia). Both stool samples and clipped nails were collected from 600 schoolchildren and microscopically screened for the presence of STHs. We also interviewed the children to gain insights into their hygiene practices. Subsequently, we explored any associations between infection, nail contamination and personal hygiene.
Results
Any STH infections were observed in 24.3% of the children (A. lumbricoides: 18.5%; T. trichiura: 9.8%; hookworm: 0.5%). The intensity of the infections was mainly low, only in a few cases a moderate-to-heavy intensity infection was observed (A. lumbricoides: 4.3%; T. trichiura: 0.2%). Other helminth species observed were Schistosoma mansoni (5.0%), Hymenolepis nana (2.7%), Taenia spp. and Enterobius vermicularis (<1.0%). The analysis of the nail material revealed the presence of A. lumbricoides (1.7%), Taenia spp. (1.0%), T. trichiura (0.5%), E. vermicularis (0.5%) and H. nana (0.2%). The odds of infection with any STH increased as the frequency of trimming decreased. The odds of nail contamination with any STH and A. lumbricoides were higher for younger children.
Conclusions
The presence of helminth eggs under the nails of children highlights a poor personal hygiene. The association between any STH infection and frequency of nail trimming needs to be explored in an intervention study. The recent prevalence of any STH infections indicated that scaling down of the frequency of deworming is justified but that STH is still a public health problem.

Abstract
BACKGROUND Enteric pathogens are often associated with exposure to food, water, animals, and feces from infected individuals. However, in sexual networks of men who have sex with men (MSM), transmission of enteric pathogens may occur during direct or indirect oral-anal contact. METHODS We performed a scoping review of the literature for studies prior to July 2019 with key terms for gastrointestinal syndromes ("proctitis," "enteritis," "proctocolitis"), enteric pathogens or sexually transmitted infections (STIs), and outbreaks using multiple electronic databases. RESULTS We identified 5861 records through database searches, bibliography reviews, and keyword searches, of which 117 references were included in the pathogen-specific reviews. CONCLUSIONS The strength of observational data describing enteric pathogens in MSM and possible sexual transmission of enteric pathogens varies by pathogen; however, a robust body of literature describes the sexual transmission of Campylobacter, Giardia lamblia, and Shigella (particularly antimicrobial-resistant strains) in sexual networks of MSM. Providers are encouraged to consider enteritis or proctocolitis in MSM as possibly having been sexually transmitted and encourage targeted STI testing. Risk/harm reduction and prevention messages should also be incorporated, though there is an acknowledged paucity of evidence with regards to effective strategies. Further research is needed to understand the transmission and prevention of enteric pathogens in MSM.

Parasitology 2022; 149:396-406.

Abstract
A cross-sectional survey to assess the prevalence of Enterobius vermicularis infection and its associated factors among the child population of infant, preschool and school age in the urban, rural and indigenous population of Iguazú city, in subtropical Argentina was presented. Additionally, the status of enterobiasis at country level was reviewed and analysed. Enterobius vermicularis presence was assessed employing an oviscopic serial sampling technique. Statistical analysis of socio-demographic determinants was performed by generalized linear mixed models at individual, household and community levels. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used to gather national information about E. vermicularis prevalence spanning the decade 2010–2020. A total of 916 children from 470 families participated. Overall prevalence was 29.8%, with 25.3, 30.7 and 34.2% detected for children inhabiting urban, rural and indigenous villages, respectively. The multi-level analysis showed that the presence of E. vermicularis was mostly determined by individual (e.g. age, playing habits, previous pinworm infection) and household-level factors (e.g. family size, overcrowding conditions). Interestingly, WASH variables, such as waste disposal, analysed at community level were also important. Data were analysed to provide eco-epidemiological features of enterobiasis in a heterogeneous subtropical child population in the same territory but with different socio-sanitary realities. The importance of promoting multi-level actions against the determinants identified, to control this public health problem integratively was evidenced. The scoping review of national data updated the state of knowledge of this parasitosis, identifying risk determinants and gaps in knowledge at country level.

Abstract
BACKGROUND Enterobiasis or oxyuriasis from Enterobius vermicularis is an infection usually localized in the large bowel and cecum. Generally, the symptoms are characterized by anal itching, and intestinal or nervous disorders. Rarely, it is responsible for death. METHODS A forensic autopsy of a 52-year-old white male inmate who died 5 days after hospitalization was performed. Histological and toxicological analyses were also performed. RESULTS The death occurred by localization of Enterobius vermicularis in the duodenum and in the proximal ileum, with intestinal haemorrhage, inflammation, and peritonitis documented by histological examination. CONCLUSION This is a common infectious disease, and can rarely occur with a fatal outcome, even in advanced populations. The lack of knowledge related to the rarity of death from enterobiasis disease can determine a dangerous concern.

Abstract
The epidemiology of neglected tropical diseases (NTD) is persistently underprioritized, despite NTD being widespread among the poorest populations and in the least developed countries on earth. This situation necessitates thorough and efficient public health intervention. Romania is at the brink of becoming a developed country. However, this South-Eastern European country appears to be a region that is susceptible to an underestimated burden of parasitic diseases despite recent public health reforms. Moreover, there is an evident lack of new epidemiologic data on NTD after Romania's accession to the European Union (EU) in 2007. Using the national ICD-10 dataset for hospitalized patients in Romania, we generated time series datasets for 2008-2018. The objective was to gain deep understanding of the epidemiological distribution of three selected and highly endemic parasitic diseases, namely, ascariasis, enterobiasis and cystic echinococcosis (CE), during this period and forecast their courses for the ensuing two years. Through descriptive and inferential analysis, we observed a decline in case numbers for all three NTD. Several distributional particularities at regional level emerged. Furthermore, we performed predictions using a novel automated time series (AutoTS) machine learning tool and could interestingly show a stable course for these parasitic NTD. Such predictions can help public health officials and medical organizations to implement targeted disease prevention and control. To our knowledge, this is the first study involving a retrospective analysis of ascariasis, enterobiasis and CE on a nationwide scale in Romania. It is also the first to use AutoTS technology for parasitic NTD.

Abstract
Background How various host–parasite combinations have been established is an important question in evolutionary biology. We have previously described two nematode species, Rhigonema naylae and Travassosinema claudiae, which are parasites of the xystodesmid millipede Parafontaria laminata in Aichi Prefecture, Japan. Rhigonema naylae belongs to the superfamily Rhigonematoidea, which exclusively consists of parasites of millipedes. T. claudiae belongs to the superfamily Thelastomatoidea, which includes a wide variety of species that parasitize many invertebrates. These nematodes were isolated together with a high prevalence; however, the phylogenetic, evolutionary, and ecological relationships between these two parasitic nematodes and between hosts and parasites are not well known. Results We collected nine species (11 isolates) of xystodesmid millipedes from seven locations in Japan, and found that all species were co-infected with the parasitic nematodes Rhigonematoidea spp. and Thelastomatoidea spp. We found that the infection prevalence and population densities of Rhigonematoidea spp. were higher than those of Thelastomatoidea spp. However, the population densities of Rhigonematoidea spp. were not negatively affected by co-infection with Thelastomatoidea spp., suggesting that these parasites are not competitive. We also found a positive correlation between the prevalence of parasitic nematodes and host body size. In Rhigonematoidea spp., combinations of parasitic nematode groups and host genera seem to be fixed, suggesting the evolution of a more specialized interaction between Rhigonematoidea spp. and their host. On the other hand, host preference of Thelastomatoidea spp. was not specific to any millipede species, indicating a non-intimate interaction between these parasites and their hosts. Conclusions The two nematode superfamilies, Rhigonematoidea and Thelastomatoidea, have phylogenetically distinct origins, and might have acquired xystodesmid millipede parasitism independently. Currently, the two nematodes co-parasitize millipedes without any clear negative impact on each other or the host millipedes. Our study provides an example of balanced complex symbioses among parasitic nematodes and between parasitic nematodes and host millipedes, which have been established over a long evolutionary history.

Abstract
Enteric helminths are common parasites in many parts of the world and in the past were much more widespread both geographically and socially. Many enteric helminths are relatively long-lived in the human host, often benign or of low pathogenicity while producing large numbers of environmentally resistant eggs voided in the faeces or found associated with individual remains (skeletons and mummies). The combination of helminth characters offers opportunities to the field of historical pathogen research that are quite different to that of some of the more intensively studied high impact pathogens. Historically, a wealth of studies has employed microscopic techniques to diagnose infection using the morphology of the helminth eggs. More recently, various ancient DNA (aDNA) approaches have been applied in the archaeoparasitological context and these are revolutionizing the field, allowing much more specific diagnosis as well as interrogating the epidemiology of helminths. These advances have enhanced the potential for the field to provide unique information on past populations including using diseases to consider many aspects of life (e.g. sanitation, hygiene, diet, culinary practices and other aspects of society). Here, we consider the impact of helminth archaeoparasitology and more specifically the impact and potential for application of aDNA technologies as a part of the archaeologists' toolkit. This article is part of the theme issue 'Insights into health and disease from ancient biomolecules'.

Abstract
Background Enterobius vermicularis infection is an important public health problem worldwide, especially among schoolchildren in tropical and subtropical countries. The prevalence of E. vermicularis infections varies in each region of Thailand; however, its status remains unknown among children who live in rural areas of the southern region. This study aimed to evaluate the current prevalence of E. vermicularis infections and to identify the risk factors for infection among schoolchildren who live in rural communities in Nakhon Si Thammarat, Southern Thailand. Results The overall prevalence of E. vermicularis infections was 5.79% (23 of 397). According to a multivariate analysis, the following were found to be risk factors associated with E. vermicularis infections (P < 0.05): those of the male sex (AOR = 4.03, 95% CI 1.22–13.29), those in the 3–6 year age group (AOR = 4.85, 95% CI 1.51–15.59), those who have a mother with a primary school education level (AOR = 11.22, 95% CI 1.75–71.77), those who have older sibling(s) (AOR = 6.25, 95% CI 1.83–21.26), those who have younger sibling(s) (AOR = 6.24, 95% CI 2.00–19.44), those who sometimes wash their hands after using the toilet (AOR = 5.25, 95% CI 1.24–22.21), those who keep their fingernails long (AOR = 29.97, 95% CI 6.16–145.85), and those who suck their fingers (AOR = 3.59, 95% CI 1.21–10.66). Conclusions This was the first report that revealed the prevalence of E. vermicularis infections among children who live in rural areas of Southern Thailand through detection using the Scotch tape technique. This study demonstrated that the high prevalence of E. vermicularis infections in schoolchildren with siblings was a significant independent predictor and that the transmission of this infection may occur in the family through their school-age siblings. In addition, children who have poor personal hygiene have a high prevalence of E. vermicularis infections. Therefore, maintaining good handwashing habits, keeping one’s fingernails short, and avoiding sucking one’s fingers should be important preventive measures against infection. Moreover, health literacy or health education, especially for parents or the principal caretakers of children, should be implemented to reduce E. vermicularis infections.

Abstract
An extra-intestinal infestation of Enterobius vermicularis (pinworm) is uncommon. We present a case of hepatic infestation of pinworm in a 57-year-old woman, misdiagnosed as a colorectal adenocarcinoma metastasis. The route of migration from the intestine to the liver is not well established but the most plausible route seems to be hematogenous. In concordance with previously published cases, the hepatic pinworm infestation is usually localised superficially in the right liver lobe. Hence solitary lesions in this location detected radiologically should be interpreted carefully. Additionally, the serum CEA level could be useful to distinguish pinworm from malignancy.

Abstract
A 16-year-old girl presented to the emergency department with intermittent fevers and worsening abdominal pain of 5 weeks duration. She had a history of travel to a less developed country and exposure to possible infectious diseases. Abdominal imaging and blood tests revealed diffuse mesenteric lymphadenopathy, elevated transaminases, and elevation of inflammatory markers. Gastroesophageal and colon endoscopies revealed gastric ulcers, and the patient was discharged with a presumptive diagnosis of systemic juvenile idiopathic arthritis given the lymphadenopathy seen on imaging, serositis, sacroiliac joint stiffness noted on physical examination, and pain relief with celecoxib. She presented again 4 days later with worsening abdominal tenderness, elevated transaminases, and new-onset abdominal distention. Tissue biopsy yielded the diagnosis and directed appropriate treatment.

Pinworm infections associated with risk of psychiatric disorders-A nationwide cohort study in Taiwan: Pinworm infections and psychiatric disorders. Compr Psychiatry 2019; 93:14-19. [PMID: 31280142 DOI: 10.1016/j.comppsych.2019.02.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 12/20/2018] [Accepted: 02/12/2019] [Indexed: 02/03/2023] Open
Abstract
AIM This study aimed to investigate the association between males with pinworm infections and the risk of developing psychiatric disorders. METHOD A total of 2044 enrolled patients, with 511 pinworm subjects and 1533 unexposed subjects (1:3) matched for sex, age and index year, from Taiwan's Longitudinal Health Insurance Database (LHID) from 2000 to 2015, selected from the National Health Insurance Research Database (NHIRD). After adjusting for confounding factors, the Cox regression model was used to compare the risk of developing psychiatric disorders during the 15 years of follow-up. RESULTS Of all the enrollees, 24 in the pinworm cohort and 18 in the unexposed cohort (343.10 vs 84.96 per 100,000 person-year) developed psychiatric disorders. The Cox regression model revealed that, after adjusting for sex, age, monthly income, urbanization level, geographic region, and comorbidities, the adjusted HR was 4.581 (95% CI: 2.214-9.480, p < .001, p < .001). Pinworm infections were associated with the increased risk in anxiety disorders, depressive disorders, and sleep disorders, respectively. CONCLUSION Patients who suffered from pinworm infections have a higher risk of developing psychiatric disorders, and this finding should be considered as a timely reminder for the clinicians to provide much more attention for these patients because of their mental health issues.

Abstract
Parasitic intestinal infections occur worldwide and affect the poorest and deprived populations. In Mexico, indigenous peoples live with the highest levels of poverty and marginalization. This study aimed to analyze the occurrence of intestinal parasites among Mayan children from the villages of Xkalakdzonot and Paraíso in Yucatán State. Stool samples from 83 children were examined using two coproparasitological tests (formalin-ethyl acetate concentration and FLOTAC Pellet techniques). The overall prevalence of intestinal parasites in children was 65.1%. Six protozoa and four helminths were identified. Blastocystis sp. (44.6%), Giardia intestinalis (26.5%), and Entamoeba coli (26.5%) were the most prevalent parasites. The prevalence of helminth infections (7.1%) was lower in children from Xkalakdzonot than in Paraíso (29.3%). The study provides relevant information on the occurrence of intestinal parasites in Mayan children from two villages. This data, therefore, can be used by local health authorities to plan appropriate programs for parasite control, considering suitable drug therapies and health education.

Enterobius vermicularis infection: prevalence and risk factors among preschool children in kindergarten in the capital area, Republic of the Marshall Islands. BMC Infect Dis 2019; 19:536. [PMID: 31215414 PMCID: PMC6580455 DOI: 10.1186/s12879-019-4159-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Accepted: 06/04/2019] [Indexed: 10/31/2022] Open
Abstract
BACKGROUND Enterobius vermicularis (pinworm) is one of the most common human parasitic helminths, and children are the most susceptible group. Some behavioral and environmental factors may facilitate pinworm infection. In the Republic of the Marshall Islands (RMI), the status of pinworm infections among children remains unknown. METHODS In Majuro City, there are 14 kindergartens with a total of 635 preschool children (PSC) whose age range of 5~6 years. The present investigation attempted to determine the pinworm prevalence and associated risk factors as well as investigate whether eggs contaminated the clothes of PSC or the ground and tables in classrooms of 14 kindergartens. Informed consent form and a self-administered questionnaire were given to parents prior to pinworm screening. Perianal specimens were collected by an adhesive scotch tape method, and clothing of belly and hip sites and the ground and tables of the classrooms were inspected using a cellophane tape method to detect any eggs contamination. RESULTS In total, 392 PSC (5.28 ± 0.56 yrs. old) participated in this project. The overall prevalence of pinworm infection was 22.4% (88/392). Boys (24.5%) had higher prevalence than girls (20.31%) (p = 0.32). PSC aged > 5 years (32.77%) showed a significantly higher prevalence than those aged ≤5 years (17.95%) (p = 0.01). A univariate analysis indicated that PSC who lived in urban areas (22.95%) had a higher prevalence than those who lived in rural areas (20.69%) (p = 0.69). The employment status of the parents showed no association with the pinworm infection rate (p > 0.05). A logistic regression analysis indicated that "having an older sister" produced a higher risk of acquiring pinworm infection for PSC compared to those who did not have an older sister (OR = 2.02; 95%CI = 1.05~3.88; p = 0.04). No significant association between various other risk factors and pinworm infection was found (p > 0.05). Also, no eggs contamination was found on the clothes of the belly and hip sites or on the ground and tables in the 14 kindergartens. CONCLUSIONS Mass screening and treatment of infected PSC are important measures in pinworm control in the RMI.

Abstract
BACKGROUND Symptomatic infection with pinworm (Enterobius vermicularis), a human pathogen, is clinically relevant in Germany, with an estimated prevalence in childhood of 2-20%. Enterobiasis can cause major mental distress. There is little systematically verified knowledge on the treatment of this condition, and there is no corresponding German guideline. This review is, therefore, intended as a summary of the current state of knowledge. METHODS This review is based on pertinent publications retrieved by a selective search in PubMed for literature appearing from 1 January 1990 to 5 February 2019 and containing the search terms "enterobiasis," "oxyuriasis," "Enterobius vermicula- ris," "pinworm," and "threadworm." RESULTS More than one billion people worldwide are thought to be infected with pinworm. Estimates of its prevalence among kindergarten and primary-school pupils in Europe are generally near 20%. Infants (<2 years of age), adolescents (>14 years of age), and adults are only sporadically affected. The main risk factors are age 4-11 years, uncontrolled anus-finger-mouth contact, nail-biting (onychophagia/peri- onychophagia), unsupervised body hygiene, and poor compliance with basic hand hygiene. No large-scale, randomized, controlled trials of treatment are available. The approved antihelminthic agents are mebendazole, pyrantel embonate, and pyrvinium embonate (success rates up to >90%). For recurrent infections, prolonged treatment for up to 16 weeks (a "pulse scheme") is recommended. CONCLUSION In nearly all cases, antihelminthic treatment along with attention to hygienic measures can successfully eradicate pinworm infection and prevent recurrence and autoinfection. The involvement of all persons living in the patient's house- hold, including sexual partners, is a prerequisite to the lasting success of treatment.

Abstract
The pinworm (Enterobius vermicularis) causes mostly mild infections characterised by nocturnal anal pruritus, mainly in children. Still, the infection is stigmatising and sleep disturbances may lead to lack of concentration. For Germany, no epidemiological data are available. Laboratory data of all patients for whom detection of E. vermicularis by cellulose tape test had been requested between 2007 and November 2017 were analysed retrospectively. E. vermicularis was detected in 971/5578 (17.4%) samples collected from 3991 patients. The detection rate increased significantly within the period of investigation. It was higher in male than in female patients (20.0 vs. 15.4%). Children 4 to 10 years old and, if also examined, their relatives were most frequently affected. Control investigations at an interval of at least 1 month, which could indicate insufficient therapy or re-infection, were performed in 90/714 patients (12.6%). While parasite detection in children < 6 years was evenly distributed throughout the year, in older patients, it peaked between October and December. In conclusion, in the area of investigation, the frequency of E. vermicularis is higher in males than in females and is subject to a hitherto undescribed seasonality. The causes of the increased frequency of parasite detection warrant further investigations.

Abstract
Enterobius vermicularis, the common pinworm, is well known in North America as a parasitic infection, mainly affecting children. It is a very contagious organism, and it is responsible for a high number of infections in the United States each year. A rise in eosinophilia is linked to most parasitic infections. However, the correlation between eosinophilia and enterobiasis infections is not well documented in the literature. In this article, we present 3 cases involving patients seen for pediatric gastroenterology consultation with concern for inflammatory bowel disease. As part of their evaluation, each patient was found to have eosinophilia of unknown significance with an ultimate diagnosis of pinworm infections made by endoscopy. Their illness presentation did not include classic enterobiasis symptoms such as rectal pruritus or nighttime irritability. These cases support a link between eosinophilia and enterobiasis that may be instructive for pediatric providers seeing patients with eosinophilia for which there is no readily apparent underlying cause.

Abstract
Lemuricola (Protenterobius) nycticebi is the only pinworm species known to infect strepsirrhine primates outside Africa, and the only pinworm species yet described in slow lorises. Here, we provided a detailed morphological comparison of female and male worms, and a first description of fourth-stage larvae collected from free-living slow lorises (Nycticebus menagensis) in Sabah, Malaysian Borneo. Using mitochondrial and nuclear markers, we also reconstructed the species' phylogenetic relationship with other pinworms infecting primates. Both morphological and molecular results indicated a distinct association between L. (P.) nycticebi and its host. However, while taxonomy identified this species as a member of the Lemuricola clade and grouped pinworms infecting lemurs and slow lorises together, phylogenetic reconstruction split them, placing L. (P.) nycticebi within the Enterobius clade. Our results suggest that L. (P.) nycticebi may represent a different taxon altogether, and that it is more closely related to pinworm species infecting Old World primates outside Madagascar. Pongobius pongoi (Foitová et al., 2008) n. comb. is also proposed. Pinworms and their primate hosts have a long history of association. L. (P.) nycticebi was recovered from slow lorises in the wild. L. (P.) nycticebi was taxonomy classified within the Lemuricola clade. However, molecular phylogenetics placed it within the Enterobius clade. Taxonomic and molecular identifications should complement species descriptions.

Abstract
Helminth infections caused by Enterobius vermicularis have a cosmopolitan character and most often affect the paediatric pre-school and school age population. The presented study was conducted to determine the prevalence of E. vermicularis in the analyzed population of children in the Eastern Slovakia. The Graham’s scotch tape method was used to investigate the presence of Enterobius vermicularis eggs in 390 specimens. The analyzed set consisted of 218 girls and 172 boys, divided by age into three groups – aged from 5 months to 2 years, aged from 3 to 6 years, and aged from 7 to 15 years. Investigation of perianal scotch tapes of children for the presence of E. vermicularis eggs revealed the prevalence of E. vermicularis was P = 3.59 %. Depending on the incidence of E. vermicularis infection, we detected no statistically significant difference (p> 0.05). The prevalence of E. vermicularis in boys was P = 4.07 %, and in girls P = 3.21 %. The highest prevalence of E. vermicularis was recorded in the group of children aged from 3 to 6 years (P = 5.03 %). Most of the samples were positive at age 4 and 5. The lowest prevalence was in the group of children aged from 5 months to 2 years (P = 0.97 %), and the prevalence of E. vermicularis in the group of children aged from 7 to 15 was P = 3.91 %. The difference in the incidence of E. vermicularis infection among different age groups of children was not statistically significant (p> 0.05). Enterobius vermicularis nematode infection and enterobiasis currently represents a major public health problem in Slovakia. At the present its occurrence is the most frequent in the paediatric population. Therefore it is important to introduce a targeted hygienic-epidemiological measure in children’s collectives, what also should include proper and effective diagnostics and frequent recurrent therapy.

Abstract
To obtain full details of gut microbiota, including bacteria, fungi, bacteriophages, and helminths, in giant pandas (GPs), we created a comprehensive microbial genome database and used metagenomic sequences to align against the database. We delineated a detailed and different gut microbiota structures of GPs. A total of 680 species of bacteria, 198 fungi, 185 bacteriophages, and 45 helminths were found. Compared with 16S rRNA sequencing, the dominant bacterium phyla not only included Proteobacteria, Firmicutes, Bacteroidetes, and Actinobacteria but also Cyanobacteria and other eight phyla. Aside from Ascomycota, Basidiomycota, and Glomeromycota, Mucoromycota, and Microsporidia were the dominant fungi phyla. The bacteriophages were predominantly dsDNA Myoviridae, Siphoviridae, Podoviridae, ssDNA Inoviridae, and Microviridae. For helminths, phylum Nematoda was the dominant. In addition to previously described parasites, another 44 species of helminths were found in GPs. Also, differences in abundance of microbiota were found between the captive, semiwild, and wild GPs. A total of 1,739 genes encoding cellulase, β-glucosidase, and cellulose β-1,4-cellobiosidase were responsible for the metabolism of cellulose, and 128,707 putative glycoside hydrolase genes were found in bacteria/fungi. Taken together, the results indicated not only bacteria but also fungi, bacteriophages, and helminths were diverse in gut of giant pandas, which provided basis for the further identification of role of gut microbiota. Besides, metagenomics revealed that the bacteria/fungi in gut of GPs harbor the ability of cellulose and hemicellulose degradation.

Abstract
Multiple Sclerosis is a chronic, progressive and debilitating neurological disease which, despite extensive study for over 100 years, remains of enigmatic aetiology. Drawn from the epidemiological evidence, there exists a consensus that there are environmental (possibly infectious) factors that contribute to disease pathogenesis that have not yet been fully elucidated. Here we propose a three-tiered hypothesis: 1) a clinic-epidemiological model of multiple sclerosis as a rare late complication of two sequential infections (with the temporal sequence of infections being important); 2) a proposal that the first event is helminthic infection with Enterobius Vermicularis, and the second is Epstein Barr Virus infection; and 3) a proposal for a testable biological mechanism, involving T-Cell exhaustion for Epstein-Barr Virus protein LMP2A. We believe that this model satisfies some of the as-yet unexplained features of multiple sclerosis epidemiology, is consistent with the clinical and neuropathological features of the disease and is potentially testable by experiment. This model may be generalizable to other autoimmune diseases.

Abstract
Although examination of the stool for ova and parasites times three (O&P ×3) is routinely performed in the United States (US) for the evaluation of persistent and/or chronic diarrhea, the result is almost always negative. This has contributed to the perception that parasitic diseases are nearly non-existent in the country unless there is a history of travel to an endemic area. The increasing number of immigrants from third-world countries, tourists, and students who present with symptoms of parasitic diseases are often misdiagnosed as having irritable bowel syndrome or inflammatory bowel disease. The consequences of such misdiagnosis need no explanation. However, certain parasitic diseases are endemic to the US and other developed nations and affect both immunocompetent and immunocompromised patients. Testing for parasitic diseases either with O&P or with other diagnostic tests, followed by the recommended treatment, is quite rewarding when appropriate. Most parasitic diseases are easily treatable and should not be confused with other chronic gastrointestinal (GI) disorders. In this review, we critically evaluate the symptomatology of luminal parasitic diseases, their differential diagnoses, appropriate diagnostic tests, and management.

Abstract
Infectious diseases including those caused by parasites can be a major threat to the conservation of endangered species. There is thus a great need for studies describing parasite infections of these species in the wild. Here we present data on parasite diversity in an agile mangabey (Cercocebus agilis) group in Bai Hokou, Dzanga-Sangha Protected Areas (DSPA), Central African Republic. We coproscopically analyzed 140 mangabey fecal samples by concentration techniques (flotation and sedimentation). Agile mangabeys hosted a broad diversity of protistan parasites/commensals, namely amoebas (Entamoeba spp., Iodamoeba buetschlli), a Buxtonella-like ciliate and several parasitic helminths: strongylid and spirurid nematodes, Primasubulura sp., Enterobius sp., and Trichuris sp. Importantly, some of the detected parasite taxa might be of potential zoonotic importance, such as Entamoeba spp. and the helminths Enterobius sp., Trichuris sp., and strongylid nematodes. Detailed morphological examination of ciliate cysts found in mangabeys and comparison with cysts of Balantioides coli from domestic pigs showed no distinguishing structures, although significant differences in cyst size were recorded. Scanning or transmission electron microscopy combined with molecular taxonomy methods are needed to properly identify these ciliates. Further studies using molecular epidemiology are warranted to better understand cross-species transmission and the zoonotic potential of parasites in sympatric non-human primates and humans cohabiting DSPA.

Abstract
Biological rhythms are thought to have evolved to enable organisms to organize their activities according to the earth's predictable cycles, but quantifying the fitness advantages of rhythms is challenging and data revealing their costs and benefits are scarce. More difficult still is explaining why parasites that live exclusively within the bodies of other organisms have biological rhythms. Rhythms exist in the development and traits of parasites, in host immune responses, and in disease susceptibility. This raises the possibility that timing matters for how hosts and parasites interact and, consequently, for the severity and transmission of diseases. Here, we take an evolutionary ecological perspective to examine why parasites exhibit biological rhythms and how their rhythms are regulated. Specifically, we examine the adaptive significance (evolutionary costs and benefits) of rhythms for parasites and explore to what extent interactions between hosts and parasites can drive rhythms in infections. That parasites with altered rhythms can evade the effects of control interventions underscores the urgent need to understand how and why parasites exhibit biological rhythms. Thus, we contend that examining the roles of biological rhythms in disease offers innovative approaches to improve health and opens up a new arena for studying host-parasite (and host-parasite-vector) coevolution.

Abstract
Summary
Enterobiasis is a human intestinal parasitic disease caused by human pinworm, Enterobius vermicularis. Despite being the most prevalent nematode infection in Europe and North America, predominantly among in school aged children, the data concerning infection rate and knowledge of genetic variability of pinworms are incomplete. The aim of the study was the estimation of prevalence and molecular typing of Enterobius vermicularis among healthy children in north-eastern Poland. In 2013 – 2015, 296 individuals (aged 2 – 18 years) from 12 kindergartens, schools and orphanages were examined by the adhesive cellophane tape method. Data on socio-demographic status were collected using a questionnaire. Molecular analysis was performed using the DNA of adult female pinworms and primers targeting the region of cytochrome oxidase I gene. The overall prevalence of enterobiasis was 10.1 %. Enterobius vermicularis infection rates were 3.9 % in children living in families and 32.8 % among the orphans (OR=0.08; 95 % CI: 0.04 – 0.19; p<0.001). There were no associations between distribution of enterobiasis and gender, pets possession and the season of examination. In 43.3 % of the infected children enterobiasis was asymptomatic. Based on a molecular marker three different haplotypes of pinworm were identified. All sequences clustered within type B, together with human E. vermicularis isolates from Denmark, Germany, Greece, and Japan. This paper provides complementary data on the occurrence and intraspecific variability of E. vermicularis in human population in Europe.

Abstract
Acute appendicitis is the most common surgical emergency worldwide. However, it can still present a challenging diagnosis especially in the young, elderly and those individuals of reproductive age, thus encompassing a wide spectrum of varied clinical presentations. Parasitic infections of the appendix are a rare cause of acute appendicitis. However, they must be considered in children presenting with abdominal pain. We report a case of Enterobius vermicularis infestation mimicking the features of acute appendicitis in a 10-year-old girl. This case is a cautionary reminder of the importance of considering E. vermicularis infestation in children presenting with abdominal pain, but who do not have a significantly raised white cell count or high Alvarado scores. A history of anal pruritus is the most characteristic symptom, but the parasites can cause severe abdominal pain mimicking appendicitis. Prompt recognition and a high clinical index of suspicion are required to prevent an unnecessary appendicectomy. Caution is advised when performing a laparoscopic appendectomy, as in our case, to prevent contamination of the peritoneum. This infestation is easily treatable with mebendazole.

Abstract
Microevolutionary processes in parasites are driven by factors related to parasite biology, host abundance and dispersal, and environmental conditions. Here, we test the prediction that isolation of host populations results in reduced genetic diversity and high differentiation among parasite populations. We conducted a population genetic analysis of two pinworms, Trypanoxyuris minutus and Trypanoxyuris atelis, commonly found parasitizing howler and spider monkeys in tropical rainforests across south-eastern Mexico, whose populations are currently isolated due to anthropogenic habitat loss and fragmentation. Mitochondrial DNA was employed to assess parasite genetic patterns, as well as to analyse their demography and population history. Both pinworm species showed high haplotype diversity but, unexpectedly, lower nucleotide diversity than that reported for other parasites. No genetic differentiation or population structure was detected in either pinworm species despite habitat loss, fragmentation and host isolation. Several scenarios are discussed that could help to explain the genetic panmixia found in both pinworm species, including higher than expected primate inter-fragment dispersal movements, and passive dispersal facilitating gene flow between parasite populations. The results suggest that large population sizes of parasites could be helping them to cope with the isolation and fragmentation of populations, delaying the effects of genetic drift. The present study highlights the complexity of the drivers that intervene in the evolutionary processes of parasites. Detailed genetic studies are needed, both in host and parasite populations, to assess the effects that habitat perturbation and environmental changes could have on the evolutionary dynamics of pinworms and primates.

Abstract
Enterobius vermicularis is one of the most common intestinal parasite in human. The main objective of this study is to determine the role of E. vermicularis in appendicitis through histopathological examination. A cross sectional study included 200 patients who had appendectomy from three hospitals in Gaza strip. The inflamed appendix was the cause of attending the hospital. Histopathological examination for each appendix was carried out. A questionnaire was designed (interview with patients who underwent appendectomy), and information were obtained from patient and analyzed by using SPSS. The study showed that 30 (15.0 %) of 200 appendices had E. vermicularis in histopathological examination. It was found that ages of patients with histologically proven E. vermicularis in appendices less than 18 years old was found to be (18.2 %). Regarding sex, (16.5 %) of females, (14.0 %) of males patients had E. vermicularis in appendices. Patients who had the highest infection with E. vermicularis were students (17.3 %). In conclusion E. vermicularis occurs more frequently inflamed appendices than in normal. From these results we can conclude that E. vermicularis could be associated to cause of appendicitis in Gaza strip.
