PLoS Negl Trop Dis 2024; 18:e0012198. [PMID: 38781272 DOI: 10.1371/journal.pntd.0012198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 06/05/2024] [Accepted: 05/06/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Toxoplasmosis is a serious endemic zoonotic disease caused by the protozoan parasite Toxoplasma gondii. Toxoplasma infection during pregnancy can result in congenital transmission and serious fetal and neonatal complications. This systematic review and meta-analysis aimed to assess the pooled seroprevalence of T. gondii infection and its determinants among pregnant women in African countries. METHODS All articles reporting the seroprevalence of toxoplasmosis among pregnant women in African countries and published from 2010 to 2023 were searched using various databases. The pooled prevalence of toxoplasmosis was calculated using a random-effect model. The variation between the included studies was assessed using a funnel plot and I2 heterogeneity statistics. To identify the sources of heterogeneity, sub-group analysis was further conducted by country, diagnostic method, and sub-African region. The association of prevalence rates with the socio-economic level and geoclimatic parameters was also explored. RESULTS In total, 29,383 pregnant women from 60 articles were included for analysis. The pooled T. gondii seroprevalence was 42.89% with high heterogeneity (I2 = 99.4%, P < 0.001). Sub-group analysis revealed variation by country (ranging from 2.62% in Namibia to 80.28% in Congo), diagnostic method used (from 8.66% in studies using a rapid diagnostic test to 55.69% in those using an agglutination test), and sub-African region (from 4.14% in regions of Southern Africa to 53.96 in Central Africa). Cat ownership (OR = 1.58) and the consumption of raw meat (OR = 1.50) and raw vegetables (OR = 1.48) had a statistically significant combined effect on T. gondii seroprevalence. No association was found between T. gondii prevalence and the level of income of the country or geoclimatic parameters. CONCLUSION The prevalence of toxoplasmosis infection among pregnant women in Africa is high, particularly in Central and Eastern Africa. The determinants of prevalence are multifactorial. Therefore, efforts should be made to increase the awareness of women concerning the risk factors for toxoplasmosis.

Baghdadi HB, Abbas I, Abdo Rizk M. Cross-sectional community-based study to assess the awareness of toxoplasmosis in Saudi Arabia. INTERNATIONAL JOURNAL OF ENVIRONMENTAL HEALTH RESEARCH 2024; 34:1776-1787.

Abstract
A few reports have been published and documented low level of awareness on toxoplasmosis among Saudi women. Herein, a cross sectional community based study was undertaken to evaluate basic knowledge on toxoplasmosis among residents in the Eastern province (Sharqiyah). Thisstudy was conducted between December 2022 and January 2023 on 334 females from different ages and educational backgrounds. Analysis of their responses revealed that only (24.9%) had heard about the disease. However, (69.8%) properly identified cats as the source of Toxoplasma gondii (T. gondii), but a smaller percentage (47.7%) knew that they might become infected through handling cat feces, and a few (26.3%) believed that bad hand hygiene can result in T. gondii infection. A few males (n = 26) have also participated, for the first time in Saudi Arabia, and displayed also low level of knowledge on toxoplasmosis. We do recommend establishing educational programs for females, in various Saudi provinces, to raise awareness on toxoplasmosis.

Abstract
BACKGROUND Toxoplasmosis is induced by Toxoplasma gondii, which affects 30 percent of the global population and is responsible for deaths related to foodborne pathogens. This study aimed to describe the seroprevalence of T. gondii infections in patients attending referral hospitals in the northwestern region of Saudi Arabia. MATERIALS AND METHODS The serology test results for T. gondii antibodies of 797 patients were retrospectively analyzed using the hospitals' database. The enzyme-linked immunosorbent assay was used to detect anti-T. gondii antibodies (IgG and/or IgM). RESULTS Overall, the prevalence of anti-T. gondii antibodies was 8.3%. Higher (9.9%) prevalence of positive results among patients aged 30 years and above was observed. Statistically, the various age groups (P = 0.031) were found to be significant. Female was noted to have increased (8.1%) seroprevalence, and the incidence of infection occurred largely among participants living in rural areas (8.2%). CONCLUSIONS Toxoplasmosis remains a public health concern. The seroprevalence of T. gondii antibodies was relatively low in the study area. IgG antibodies to T. gondii were mainly detected. Increasing awareness on the mode of transmission, source of infection, and disease prevention through health education and dissemination is vital to reduce or eliminate toxoplasmosis.

SAGE Open Med 2023; 11:20503121231202230. [PMID: 37915843 PMCID: PMC10617264 DOI: 10.1177/20503121231202230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 08/31/2023] [Indexed: 11/03/2023] Open
Abstract
Objectives The study determined the rate of recent and past Toxoplasma gondii infections, associated factors, and awareness among expectant mothers assessing antenatal care in a tertiary hospital in Nigeria. Methods This prospective cohort study was conducted among pregnant women. A questionnaire was used to gather information on socio-demographics, infection risk factors, and awareness of the infection. Using an ELISA kit, the IgG and IgM antibodies against Toxoplasma gondii were assessed in blood samples from these women. For samples that tested positive for IgM, a real-time polymerase chain reaction was used to amplify the DNA. SPSS version 23 was used for data entry and analysis. The p-value < 0.05 was adjudged to be significant. Results A total of 250 pregnant women participated in the study. The rate of recent infection (IgM antibody positivity) was 3.6% (9/250), while past infection (IgG antibody positivity) was 68.4% (171/250). Polymerase chain reaction confirmed 5/9 recent infections as positive. Factors significantly associated with toxoplasmosis were gardening (p = 0.037) and undercooked meat (p = 0.023). Only 27 out of 250 pregnant women in this research had heard of toxoplasmosis, which translates to a low awareness rate of 10.8%. Conclusions The recent infection among pregnant women in this study indicates the possibility of mother-to-child transmission with attendant sequelae. There was a significant association between past Toxoplasmosis gondii infections and stillbirth. Routine screening for toxoplasmosis should be incorporated into the antenatal program since none of the symptoms could significantly predict illness. In addition, regular antennal care instruction should cover toxoplasmosis education.

Abstract
Background Cytomegalovirus (CMV) is the most common intrauterine congenital infection in humans. Worldwide seropositive rates of CMV are considerably high among women of childbearing age. There is currently no optimal drug treatment nor a vaccine for congenital CMV infection and therefore the best available program to date of prevention is practicing standard hygienic measures. The success of this program relies on women’s knowledge of CMV modes of transmissions, and risk and preventative behaviors. Objective The current study aims to assess the awareness and knowledge of CMV infection among women in Saudi Arabia. Method In this cross-sectional study, an online self-administered questionnaire was distributed to women 18 years of age or older residing in all regions of Saudi Arabia. The questionnaire included questions to assess awareness of CMV, knowledge of symptoms, transmission, and preventative measures of CMV infection. Results Out of the 1004 women who completed the questionnaire, self-reported knowledge of CMV was considerably low with only 82 women (8.17%) having heard of CMV infection. Most women reported learning about CMV from the internet and university. In binary logistic analyses, women pursuing studies in healthcare and those working in health professions, as well as those with undergraduate and graduate college degrees were significantly associated with higher knowledge of CMV. Urban area of residence was significantly associated with lower levels of knowledge of CMV. Among women who reported they had heard of CMV, their knowledge of CMV modes of transmission, symptoms, and preventative measures was considerably low. Regarding the transmission route, 23% reported no knowledge of modes of transmission, 59.75% reported mother-to-child transmission, 48.78% reported sexual intercourse, and 45% reported contact with body fluids of an infected person. Regarding knowledge of symptoms of congenital CMV, mental retardation and death were the most commonly reported clinical presentations. Conclusion The current study showed that the overall knowledge of CMV is very low among women in Saudi Arabia. Working in the healthcare field and higher education levels were significantly associated with better knowledge of CMV. It is crucial that women are provided with information regarding CMV-associated complications and preventative measures against mother-to-fetus transmission of CMV.

Abstract
Objective: Toxoplasma gondii (T. gondii) is a life-threatening parasite particularly infecting the immunocompromised women. Deficiency of vitamin D is well reported in several infectious disorders. This study was undertaken to investigate a correlation of vitamin D deficiency with the onset of T. gondii infection in immunocompetent women from the central of Saudi Arabia. Methods: Blood samples were collected from 304 Saudi women from the Qassim region of Saudi Arabia. Specific immunoassays were used to determine the levels of T. gondii immunoglobulin G and vitamin D. The SPSS and the Prism Graph Pad statistical software were used for the data analysis. Results: Out of 304 women, 18.8% were found to be positive for toxoplasmosis. Interestingly, the serum levels of vitamin D in toxoplasma positive cases were found to be significantly low as compared with the levels of vitamin D in toxoplasma negative cases. Moreover, sociodemographic risk factors such as age, residence location, and consumption of fruits/vegetables were also found to be associated with vitamin D deficiency and with the seroprevalence of toxoplasmosis. Conclusion: This study investigated a direct correlation of vitamin D deficiency with the severity of the toxoplasmosis in Saudi women. Therefore, it is predicted that vitamin D supplementation may provide protection against toxoplasma infection.

Abstract
BACKGROUND Although toxoplasmosis is asymptomatic in most cases among pregnant women, it may cause newborn abortions and birth defects if the infection occurs during pregnancy. Therefore, raising awareness and promoting good practices of pregnant women towards toxoplasmosis disease is essential to avoid infection during pregnancy. The aim of this cross-sectional study is to assess toxoplasmosis awareness and its risk-related behavior pregnant women who attended public health centers in one of the biggest Moroccan cities: Casablanca. METHODS A structured questionnaire was used to collect data including socio-demographics data, awareness of etiology, modes of transmission and preventive practices towards toxoplasmosis. RESULTS This study survey showed that among 390 pregnant women interviewed, 41.2% reported having heard or read information regarding toxoplasmosis. Only 8.1% of them knew that toxoplasmosis is a parasitic disease caused by Toxoplasma gondii, and 13.7% of those who gave a correct answer were aware that the host of toxoplasmosis is cats. There is a significant statistical association between age, level of education and profession of pregnant women and toxoplasmosis awareness. Despite of the majority of the interviewed pregnant women had had effective preventive practices towards toxoplasmosis, 17.4% of pregnant women were convinced that Toxoplasmosis can transmit to the fetus and 14.3% stated it is asymptomatic in most cases. CONCLUSION This study highlights the low level of knowledge and awareness of toxoplasmosis among pregnant women in Casablanca/Morocco. Therefore, a special education program targeting all women during their reproductive age is necessary.

Abstract
Toxoplasmosis is caused by Toxoplasma gondii, an apicomplexan parasite that is able to infect any nucleated cell in any warm-blooded animal. Toxoplasma gondii infects around 2 billion people and, whilst only a small percentage of infected people will suffer serious disease, the prevalence of the parasite makes it one of the most damaging zoonotic diseases in the world. Toxoplasmosis is a disease with multiple manifestations: it can cause a fatal encephalitis in immunosuppressed people; if first contracted during pregnancy, it can cause miscarriage or congenital defects in the neonate; and it can cause serious ocular disease, even in immunocompetent people. The disease has a complex epidemiology, being transmitted by ingestion of oocysts that are shed in the faeces of definitive feline hosts and contaminate water, soil and crops, or by consumption of intracellular cysts in undercooked meat from intermediate hosts. In this review we examine current and future approaches to control toxoplasmosis, which encompass a variety of measures that target different components of the life cycle of T. gondii. These include: education programs about the parasite and avoidance of contact with infectious stages; biosecurity and sanitation to ensure food and water safety; chemo- and immunotherapeutics to control active infections and disease; prophylactic options to prevent acquisition of infection by livestock and cyst formation in meat; and vaccines to prevent shedding of oocysts by definitive feline hosts.

Abstract
Toxoplasma gondii (T. gondii) infection causes serious problems leading to maternal complications and foetal anomalies during pregnancy. The aim of this study was to identify risk factors for toxoplasmosis and to determine the seroprevalence of the disease with regard to the awareness levels of patients. A total of 214 pregnant women who were admitted to Karabuk University, Gynaecology and Obstetrics Clinic between July 2018 and November 2018 and accepted to participate were included this cross-sectional study. Venous blood samples were obtained and anti-T. gondii IgG and IgM levels were analysed. The demographic characteristics of the patients were recorded and a questionnaire investigating about T. gondii risk factors were completed. The relationship between toxoplasmosis and risk factors was evaluated using multivariate regression analysis. The prevalence of toxoplasmosis among the pregnant women was 14% (35/214). The potential risk factors of toxoplasmosis were primigravidity (AOR = 2.56 95% CI: [1.26-8.26]), cat ownership (AOR = 10.29, 95% CI: [3.58-29.60]), and sausage/salami consumption (AOR = 2.96, 95%CI: [2.10-7.46]);22.4% of the women were aware of toxoplasmosis, and awareness was significantly higher in multigravida women compared with primigravida women (p=.042). Congenital toxoplasmosis can be prevented through pregnancy screening programmes and education aimed at increasing awareness and protection.IMPACT STATEMENTWhat is already known on this subject? The seroprevalence of toxoplasmosis is very variable and may differ significantly between countries, and even different geographic regions of the same country. Raising awareness of the disease among persons in risk groups through education is a primary objective in prevention.What do the results of this study add? T. gondii seropositivity was found to be related with being primigravid, cat ownership and having close contact with cats, and consumption of meat products such as salami and sausages. In addition, primigravidity is a risk factor for toxoplasmosis because the awareness of the disease was lower than in multiparous women.What are the implications of these findings for clinical practice and/or further research? It should also be known that women of childbearing age are in the high-risk group for toxoplasmosis, and studies on preventive measures should be performed. Increased awareness can prevent infection and the possibility of complications due to congenital toxoplasmosis, especially in the reproductive period of women.

Abstract
Toxoplasmosis is a worldwide zoonotic infectious disease caused by Toxoplasma gondii. This infection is estimated to affect about a third of the world's population. The aim of this study was to evaluate the knowledge of Italian women about toxoplasmosis and its forms of transmission, clinical manifestations, diagnosis and prevention through two different modalities (e-research and traditional research). In a cross-sectional study, 808 Italian women were interviewed, using a self-administered questionnaire, through two different modalities: an e-research or web survey and a traditional paper research and 84% reported to have heard about toxoplasmosis, but from most of the sample, it resulted that the knowledge of the protozoan disease was superficial and incomplete.The assessment of the dimensionality related to the toxoplasmosis knowledge's instrument showed that the scale is composed by two stable and reliable factors which explain 58.6% of the variance: (a) the basic knowledge (α = 0.83), which explains the 45.2% of the variance and (b) the specialist knowledge (α = 0.71), which explains the 13.4% of the variance. The variance and the multiple linear regression data analysis showed significant predictors of correct basic knowledge of toxoplasmosis: the highest age, the highest degree of study, to have previously contracted illness or to know someone who had contracted it, to be working or to be housewives. In conclusion, this study showed limited awareness of toxoplasmosis and suggested the implementation of effective education and learning programs. The results also showed that online data collection, in academic research, might be a valid alternative to more traditional (paper-and-pencil) surveys.

Abstract
Aim This study aimed to assess toxoplasmosis-related knowledge, attitudes and preventive practices among female undergraduate students in Beni-Suef University, Egypt. Subjects and methods A cross-sectional design with a multi-stage random sample of female Beni-Suef university students were recruited in this survey over a period of 8 weeks' duration using a self-administrated questionnaire. Results Among 1079 female students, only 35 (3.2%) had good knowledge. Female students of the Health Care faculty and students from rural areas had a significantly higher rate of good knowledge. The results also illustrated that most of the studied sample (63%) had a negative attitude. Nearly one-third of participants were convinced that toxoplasmosis shows symptoms and only (25.6%) agreed about the occurrence of toxoplasmosis infection during pregnancy. A significant positive correlation was found between the total knowledge score and the total attitude score of female students, indicating that students with better knowledge had more positive attitudes. Of the participants, 67.1% always ate fast food, while 70.7%, 72% and 78.2% of female students reported hand washing after gardening, cleaning areas where cats were and cooking with meat, respectively. Conclusion Knowledge regarding toxoplasmosis was deficient among female students attending Beni-Suef University, and they had a negative attitude regarding toxoplasmosis. There was also a positive correlation between students' knowledge and their attitude toward toxoplasmosis infection. Many students avoided risk behaviors in the correct way, without realizing what they avoided. There is a critical need for efficient educational programs to raise the population's awareness regarding toxoplasmosis.

Abstract
Background: Toxoplasma gondii (T. gondii) is one of the most prevalent infectious parasites in humans worldwide. The diagnosis of toxoplasmosis is based on serological screening through the detection of anti-toxoplasmosis antibodies: IgG, which indicates previous exposure and the presence of active immunity, and IgM, which indicates a recent infection. We aimed to determine the prevalence of anti-toxoplasma antibodies in pregnant women at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, and explore the cost-effectiveness of anti-toxoplasma screening. Method: This was an analytic retrospective study of women who underwent serology testing for anti-toxoplasmosis antibodies at KAUH in 2013-2018. Data were collected from hospital documentation and IBM Statistical Package for Social Sciences (SPSS Inc., Chicago, IL) version 22 was used for analysis. Result: Of the 9,098 pregnant women seen at KAUH, 2,754 had undergone the test, and 38 had a positive result, i.e., a seroprevalence rate of 1.4%. Most women were Saudis (57.9%), and almost all were multiparous. Of those with a positive result, 36.8% were in the third trimester. Most births were by spontaneous vaginal delivery (65.8%). Twelve (31.6%) of the women with toxoplasmosis experienced obstetric complications. The estimated total cost of screening the pregnancies was US $919,646.00 Conclusion: The prevalence of pregnant women with a positive anti-toxoplasmosis test result was low, and we believe there is no net benefit from screening all pregnant women for toxoplasmosis. Primary prevention should be through health education, and we recommend screening only women with high-risk pregnancies.

Abstract
Parasitic diseases are among the major health problems of various societies, especially people in developing countries, causing high economic and mortality burdens. Many researchers have reported that awareness and knowledge of a disease are effective in preventing and controlling the disease. The aim of the present study was to assess the knowledge and attitudes on parasitic diseases of the population in Ahvaz County, southwestern Iran. This community-based cross-sectional study was carried out in 2017 on 3500 subjects above 15 years old of Ahvaz County. First, participants were provided the necessary information regarding the study, and then data were collected using a constructed questionnaire. Of the 3500 participants, 1732 (49.5%) were female and 1768 (50.5%) were male, 348 (9.9%) said that they had been infected with a parasitic disease at least once in their lifetime. Almost half of the participants (42.8%) knew malaria was a parasitic disease and 50.2%, 48.9%, and 41.5% were aware of the possible transmission of parasitic diseases through uncooked meat, dirty hands, and close contact with animals. Regarding clinical symptoms, 73.2% and 32.6% of the respondents knew diarrhea and abdominal pain respectively were clinical symptoms of intestinal parasitic diseases. However, only 31.3% were aware of the close contact with cats and the risk of human toxoplasmosis and possible abortion in pregnant women. The findings reveal that the attitude of most participants toward treatment was positive (93.9%), but only 47.5% of believed that disinfecting fruits and vegetables could prevent intestinal parasitic infections.

Abstract
Background In Saudi Arabia, the prevalence of toxoplasmosis is high. However, to date, few studies have evaluated the degree of knowledge on toxoplasmosis among females in Saudi Arabia. Objectives The objective of this study was to assess the knowledge, attitude and preventive behavior regarding toxoplasmosis among female students at Jazan University, Jazan, southwest Saudi Arabia. Materials and Methods This cross-sectional study was conducted on a random sample of 440 female students at Jazan University using a semi-structured, self-administered questionnaire. Data with numerical/qualitative variables were expressed as frequency and percentage. Chi-square test was used to analyze categorical variables. P < 0.05 was used to indicate statistical significance. Results This study found that more than three-quarters (79.1%) of the students had insufficient knowledge about toxoplasmosis. Students from healthcare faculties had higher knowledge scores (28.5%) than students from arts and humanities (20.6%) and science (18.9%) faculties; however, the differences were not statistically significant (P = 0.77). The majority of the studied sample (92.3%) was found to eat fast food on a regular basis. About 42%, 54% and 4% of the respondents reported that they never, occasionally and always ate improperly washed vegetables, respectively. Conclusions This study found that a substantial proportion of Jazan University's female students have insufficient knowledge on toxoplasmosis. Health educational programs are necessary to increase the awareness and knowledge about toxoplasmosis and its clinical manifestations.

Abstract
Background The seroprevalence of Toxoplasma gondii ranges widely in different areas of the world and different populations. Although toxoplasmosis is typically benign and asymptomatic, it induces major complications in immunocompromised individuals and during pregnancy. Prevention of maternal primary infection constitutes the major tool for avoiding congenital T. gondii infections and toxoplasmosis complications. The preventive measures depend on the women’s knowledge about toxoplasmosis. The aim of the study was to assess the knowledge on toxoplasmosis among pregnant women in Poland. Methods The study was conducted between October 2016 and January 2017 in 3 Polish cities. During a visit in a hospital outpatient clinic, pregnant women aged > 16 years fulfilled a previously validated questionnaire. The questions concerned personal data (age, parity, educational level, place of residence), toxoplasmosis knowledge (etiology, routes of transmission, symptoms, sequelae), and sources consulted to collect information. Results Overall, 465 pregnant women participated in the survey; 439 (94.4%) were aware of toxoplasmosis. Toxoplasmosis was perceived as a zoonotic disease by 77.4%, as a parasitic disease by 41.7%, as a disease transmitted through poor hand hygiene by 8.6%, as a childhood illness by 4%, and as a congenital disease by 0.4%. Regarding the transmission route, 84.5% of women pointed at a domestic cat, 46.7% at eating raw or undercooked meat. The total of 84.3% did not know toxoplasmosis symptoms, and 12.0% stated that they did not present the symptoms. In multivariate analysis, younger age (OR, 2.74; 95% CI, 1.67–4.49; p < 0.001), city residence (OR, 13.45; 95% CI, 3.12–57.89; p < 0.003), and higher education level (OR, 6.81; 95% CI, 3.69–12.59; p < 0.001) were significantly associated with better knowledge of toxoplasmosis, and the number of children (OR, 0.32; 95% CI, 0.22–0.48; p < 0.001) – with higher knowledge of the symptoms. Conclusions Among pregnant women in Poland, the basic knowledge on toxoplasmosis is very high (94.4%). Younger age, city residence, higher education level, and the number of children turned out significantly associated with better knowledge of T. gondii and toxoplasmosis symptoms.

Abstract
Toxoplasma gondii (T. gondii), which infects many warm-blooded animals including humans, causes toxoplasmosis, a globally widespread condition. To date, no research has explored the overall T. gondii infection seroprevalence among women in Saudi Arabia, nor have the risk factors associated with the infection been examined in the Saudi Arabian context. The present systematic review and meta-analysis therefore aimed to investigate toxoplasmosis seroprevalence based on previous study samples of Saudi women of reproductive age, and to establish the potentially risk factors in this national context. PubMed, Science Direct, and Scopus were searched for studies on T. gondii seroprevalence among women in mainland Saudi Arabia published between January 2000 and December 2017. Seroprevalence with 95% CI was presented for each study, and point estimates and their 95% CIs of pooled seroprevalence were then calculated. Twenty papers were eligible for inclusion, with samples totaling 13,597 females of childbearing age (ie, between 15 and 49 years) covering various regions of Saudi Arabia. The pooled estimation for T. gondii prevalence using a random-effect model was calculated as 27.8% (95% CI =20.6%–36.3%). A significant association was observed between age and T. gondii seroprevalence. This review represents the first comprehensive and systematic evaluation of T. gondii infection seroprevalence among Saudi Arabian women, and reports a high prevalence of Toxoplasma infection. Further research is required to support the development of more cost-effective preventive strategies.

Abstract
Toxoplasma gondii is an intracellular protozoan parasite infecting human and almost all warm-blooded animals. It may cause several severe symptoms if pregnant women infection with T. gondii, including misbirth. A cross-sectional study was conducted containing 313 Manchu pregnant women attending antenatal care from 2016 to 2017 in Jilin province, northeastern China, and were assessed by enzyme-link immunosorbent assay and the study utilized univariate analysis to identify the potential risk factors for T. gondii infection. Of the 313 investigated Manchu pregnant women, 51 (16.29%, 95% CI 12.2-20.4) were tested as T. gondii-seropositive, with 47 (15.02%) seropositive for T. gondii IgG antibodies and 8 (2.56%) IgM positive. The seroprevalence of T. gondii in different age groups varied from 13.50% (8.7-18.3) to 23.90% (13.9-41.9). Pregnant raising cat at home has a significantly higher seroprevalence of T. gondii than no cat at home. Pregnant consuming raw/undercooked meat has a significantly higher T. gondii seroprevalence than individuals did not consuming raw/undercooked meat. This is the first study of T. gondii infection seroprevalence in Manchu pregnant women. Risk factors analysis suggested that seroprevalence of T. gondii in investigated Manchu pregnant women was mainly related to consumption of raw/undercooked meat and raising cat at home. The findings will provide key and baseline data for prevention and control of toxoplasmosis among Manchu pregnant women and other people.

Abstract
Objectives Toxoplasma gondii (T. gondii) is a serious public health issue, but limited data has been published to date on the seroprevalence of T. gondii infection in Saudi Arabia. Therefore, this study aimed to establish the seroprevalence and risk factors of T. gondii infection using a sample of females enrolled at a university in Northern Saudi Arabia. Methods Using a cross-sectional research approach, we recruited a convenience sample of 180 healthy females studying at the University of Tabuk between February and June 2016. We used a questionnaire to gather sociodemographic data on the participants to establish the risk factors leading to exposure to toxoplasma. Blood samples were taken from the participants and analyzed to detect T. gondii antibodies (immunoglobulin M and immunoglobulin G) via the enzyme-linked immunosorbent assay technique. Multivariate logistic regression modeling was employed to establish the potential predictor variables for T. gondii infection. Results Of the 180 participants, 17 (9.4%) were seropositive for T. gondii IgG. None tested positive for IgM antibodies exclusively. The sole variable positively associated with seropositive T. gondii IgG was the participants' consumption of raw, unwashed fruit or vegetables (odds ratio = 3.36, 95% confidence interval: 1.11-10.22). Conclusions Our findings emphasize the need for higher awareness of toxoplasmosis in Saudi Arabia, specifically knowledge of the way toxoplasma infection occurs so that women can more easily avoid it. Large-scale research is therefore required to inform the design of future public health interventions.

Abstract
Background: Toxoplasma gondii is a zoonotic parasite that has arisen as an important opportunistic infection that causes morbidity and mortality especially in HIV positive patients. This study was carried out to determine the sero-prevalence of T. gondii (IgG and IgM) and the associated risk factors among HIV positive and negative patients in Northern South Africa. Materials and Methods: The study was conducted in the Vhembe District in Limpopo province from April 2012 to January 2013. A well-structured questionnaire was used to collect socio-demographic information and possible risk factor information on toxoplasmosis from participants. A total of 161 blood samples of both HIV positive and negative patients visiting the local clinics in the Vhembe district were collected. Serum samples were tested for IgG and IgM against T. gondii using commercially available ELISA protocol. Results: The prevalence of T. gondii IgG was 31.7% while that of T. gondii IgM was 4.9%. The prevalence of T. gondii IgG was higher in HIV positive patients (38%) compared to 16.7% among HIV negative patients (p=0.001). Toxoplasma gondii IgG antibodies were more common in patients who were not taking ARV’s (46.2%) compared to those who were taking ARV’s (35.2%) (P<0.001). Conclusions: The present study has shown a high prevalence of T. gondii (IgG) among patients attending different HIV clinics in the Vhembe district with no current infections among pregnant women. In addition to the sero-positive status of the patient to HIV, other significant risk factors for toxoplasmosis included high viral load, non-adherence to ARV therapy and age (>25 years).
