Abstract
BACKGROUND miRNAs are known as non-coding RNAs that can regulate gene expression. They are reported in many microorganisms and their host cells. Parasite infection can change or shift host miRNAs expression, which can aim at both parasite eradication and infection. PURPOSE This study dealt with examination of miRNA expressed in intestinal protozoan, coccidia , as well as profile changes in host cell miRNA after parasitic infection and their role in protozoan clearance/ survival. METHODS The authors searched ISI Web of Sciences, Pubmed, Scholar, Scopus, another databases and articles published up to 2024 were included. The keywords of miRNA, intestinal protozoa, toxoplasma and some words associated with topics were used in this search. RESULTS Transfection of miRNA mimics or inhibitors can control parasitic diseases, and be introduced as a new therapeutic option in parasitology. CONCLUSION This review can be used to provide up-to date knowledge for future research on these issues.

Abstract
The genetically related assemblages of the intestinal protozoa parasite Giardia lamblia are morphologically indistinguishable and are often derived from specific hosts. The Giardia assemblages are separated by large genetic distances, which might account for their relevant biological and pathogenic differences. In this work, we analyzed the RNAs cargo released into exosomal-like vesicles (ElVs) by the assemblages A and B, which differentially infect humans, and the assemblage E, which infects hoofed animals. The RNA sequencing analysis revealed that the ElVs of each assemblage contained distinct small RNA (sRNA) biotypes, suggesting a preference for specific packaging in each assemblage. These sRNAs were classified into three categories, ribosomal-small RNAs (rsRNAs), messenger-small RNAs (msRNAs), and transfer-small RNAs (tsRNAs), which may play a regulatory role in parasite communication and contribute to host-specificity and pathogenesis. Uptake experiments showed, for the first time, that ElVs were successfully internalized by the parasite trophozoites. Furthermore, we observed that the sRNAs contained inside these ElVs were first located below the plasma membrane but then distributed along the cytoplasm. Overall, the study provides new insights into the molecular mechanisms underlying the host-specificity and pathogenesis of G. lamblia and highlights the potential role of sRNAs in parasite communication and regulation.

[PMID: 36846671 PMCID: PMC9946859 DOI: 10.1016/j.heliyon.2023.e13243] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Revised: 01/13/2023] [Accepted: 01/23/2023] [Indexed: 01/29/2023] Open
Abstract
Giardia duodenalis is one of the common intestinal parasites causing diarrhea in humans and livestock, including pigs. Thus, a healthy livestock would result in a clean environment, which benefits humans. In the present study, the global molecular prevalence of G. duodenalis infection was determined in pig populations, through systematic exploration of 4 international databases (MEDLINE/PubMed, Scopus, Web of Science, and Google Scholar) until March 4th, 2022. A random-effects meta-analysis model was used to estimate the overall and subgroup-based pooled prevalence of G. duodenalis, and I 2 index was used for the evaluation of the heterogeneity. Altogether, 42 datasets from 18 papers examined 7272 pigs across 12 nations, showing a 9.1% (95% CI: 5.6-14.3%) pooled molecular prevalence. Sensitivity analysis demonstrated no remarkable variation in the reported total prevalence upon removing individual studies. It was found that 6 Giardia assemblages (A-F) are capable to infect pigs around the world, including assemblage E [16 datasets, 41.1% (95% CI: 24.8-59.6%)], B [8 datasets, 28.2% (95% CI: 12.2-52.6%)], D [3 datasets, 16.2% (95% CI: 10.6-24.1%)], C [3 datasets, 11.6% (95% CI: 7.3-17.9%)], and A [11 datasets, 9.9% (95% CI: 5.6-16.9%)]. Of note, assemblage F was only reported in one study. Meta-regression analysis showed that publication year was not significantly associated with the Giardia prevalence in swine population, in contrast to the sample size. Substantially, animals in weaner and fattener stages were more prone to giardiasis. Assemblages A and B are of utmost zoonotic significance for humans, while assemblages C, D and F have, also, been found in dogs and cats. Still, little is known on the prevalence and distribution of Giardia assemblages in pigs and requires more extensive and detailed studies.

Abstract
Giardiasis is a common, treatable intestinal disease that adversely affects underprivileged communities living in unsanitary conditions. Giardiasis causes a wide spectrum of gastrointestinal diseases in those infected, ranging from subclinical disease that can manifest as irritable bowel syndrome with persistent abdominal symptoms. Importantly, giardiasis has been identified as a predictor of malnutrition among young children in rural areas and as a cause of waterborne mass epidemics endangering not only humans but also animals in a broad clinical, social, and economic spectrum. While the diagnosis of giardiasis is heavily dependent on the presence of cysts and/or trophozoites detected using microscopy, the intermittent cyst excretion, low infection intensity, and low sensitivity method m4akes fecal examination unrewarding, thus urging the need for an improved diagnostic method for giardiasis. Proteins are key compounds in biosynthesis, cells, tissues, and organ signaling, carrying important information related to biological and pathogenic processes, as well as pharmacological responses to therapeutic intervention, and are therefore important indicators for determining disease onset, progression, and drug treatment effectiveness. In connection with this, proteins could serve as promising biomarkers for antigen-antibody detection, as well as vaccine candidates. This article is aimed at providing a comprehensive overview of proteins, serological, molecular, inflammatory, volatile, and hormonal biomarkers associated with giardiasis and their potential for diagnostics and therapeutics.

Abstract
Strongyloidiasis is a parasitic disease, very rare in countries like Spain, caused by the Strongyloides stercoralis nematode. We present a case of a 5-year-old patient from Ecuador who came to the Emergency Department due to fever, colicky abdominal pain, watery diarrhea, and occasional vomiting of several days of evolution. In laboratory studies, a marked leukocytosis with eosinophilia stands out, for which reason a microscopic study of the stool was carried out where larval forms compatible with Strongyloides stercoralis were observed. The diagnostic strategy of parasitic infection in developed countries is highly influenced by the low prevalence and diversity of the parasitic species, causing the diagnosis, on many occasions, to be a challenge. In the presence of eosinophilia and abdominal symptoms, it is recommended to orient the diagnosis towards a possible infection of parasitic origin to make an early diagnosis of the infection and avoid possible serious complications.

Abstract
MicroRNAs (miRNAs), a subclass of small regulatory RNAs that present from ancient unicellular protozoans to parasitic helminths and parasitic arthropods. MiRNAs' mode of action has attracted wide attention as a result of their unique functional importance. MiRNAs play a role in diverse physiological and pathological processes ranging from organ development, immune function to apoptosis and cancer at the post-transcription gene expression. Thus, miRNAs are known to be targets for clinical treatment and therapy. The discovery of the high stability of circulating miRNA in various types of host body fluids, such as whole blood, serum, plasma, saliva, and urine has increased great interest among researchers in the potential of circulating miRNA as a prognosis/diagnosis of infectious. Some circulating miRNAs biomarkers advanced to clinical applications related to human diseases. However, this idea starts to come only in the fields of infectious disease. The goal of this review is to enhance the current understanding of these molecules and their applicability in the field of medicine. A detailed review of the available literature consulting tools performed in online repositories such as NCBI, PubMed, Medline, ScienceDirect, and UpToDate. This review summarizes an overview of preclinical studies using circulating miRNAs biomarkers against infectious diseases affecting humans. The use of miRNA as a safe and potential tool is encouraging news, considering that until now, guidelines for the use of miRNA in clinical practice are still lacking.

Role of Polymerase Chain Reaction in Stool and Duodenal Biopsy for Diagnosis of Giardiasis in Patients with Persistent/Chronic Diarrhea. Dig Dis Sci 2020; 65:2345-2353. [PMID: 31955285 DOI: 10.1007/s10620-019-06042-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Accepted: 12/31/2019] [Indexed: 12/09/2022]
Abstract
BACKGROUND Giardia duodenalis is a common cause of chronic diarrhea especially in tropical countries. Diagnosis is based on microscopy (three stool samples) for trophozoites/cysts. Role of stool or duodenal biopsy PCR as a diagnostic method needs to be defined. We conducted a prospective study to determine the diagnostic characteristics of G. duodenalis stool and duodenal biopsy PCR in comparison to stool microscopy (reference standard). Later, we compared other techniques with stool PCR, considering it as new reference standard and characterized the type of Giardia assemblage. METHODS G. duodenalis stool nested PCR was first evaluated using 40 positive controls and 50 negative controls considering stool microscopy as reference standard. Patients with chronic diarrhea (n = 100) were evaluated by stool microscopy and nested PCR. In 30 patients in whom upper gastrointestinal endoscopy was performed, duodenal biopsy samples were obtained and evaluated by histopathology, imprint cytology, and nested PCR. The type of Giardia assemblage was detected by assemblage-specific PCR. RESULTS Stool nested PCR was found to have sensitivity and specificity of 100% and 94%, respectively, compared to stool microscopy. In patients with chronic diarrhea, 48% had evidence of Giardia infection. Stool microscopy detected 65%, stool PCR detected an additional 27%, and duodenal biopsy PCR detected an additional 8% of cases. The commonest assemblage found was assemblage B. Clinical and demographic characteristics were similar in patients harboring either assemblage A or B. CONCLUSION Stool PCR is more sensitive than stool microscopy. By utilizing stool microscopy, stool nested PCR, and duodenal biopsy PCR in sequential manner, diagnostic yield can be increased.
