Cats play a significant role in environmental contamination and the transmission of parasites. The goal of the present study was to investigate the prevalence of Toxoplasma gondii (T. gondii) and Toxocara spp. infection among stray cats at Ahvaz Jundishapur University of Medical Sciences campus. The current descriptive study began with the collection of 170 fresh cat faecal samples from various sites in the Ahvaz Jundishapur University of Medical Sciences area. Sheather's sugar flotation method was applied to all specimens, and parasites were identified and examined microscopically. Next, a nested-PCR assay, sequencing, and real-time PCR with high-resolution melting curve (HRM) analysis were performed. In this study, out of 170 cat faecal samples microscopically evaluated, 8 (4.70%) and 37 (21.76%) were infected with T. gondii oocysts and Toxocara eggs, respectively. Using nested PCR, 8 out of 170 samples (4.70%) were found to be infected with T. gondii. HRM analysis showed that all isolates could be classified into three genetic lineages. Considerable prevalence, exceeding 50% for Toxocara and surpassing 25% for Toxoplasma in certain instances, along with genetic diversity, was observed in the present study. Hence, it is suggested that all individuals, including kindergarten children, students, employees, workers, and pregnant women who are in contact with their surroundings, take the necessary precautions.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"70 2","pages":"101-111"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to its effects on mycobacterial diseases, the information has shown the protection effect of BCG in helminthic diseases. In the current review, the role of BCG vaccine in non-specific protection helminthic infection is reviewed. In human alveolar echinococcosis (AE), treatment with BCG enhances host's innate immune response against the parasite via the number and activation of monocytes. In cysticercosis, despite the enhancement of Th1-biased immune responses by coadministration of rcC1 plus BCG-DNA, the level of induced protection did not increase compared to immunization with rcC1 antigen alone. Also, pretreatment of mice with live BCG vaccine induced a high level of protection against subsequent parasite infection with Taenia taeniaeformis. The reduction of the parasite burden in mice infected with Mesocestoides corti that received two doses of BCG post-infection demonstrated the therapeutic effect of BCG. The protective potential of the schistosomula/BCG vaccine against Schistosoma japonicum in sheep study showed a reduction in the number of adult worms and mean faecal egg counts post-challenge. In trichinellosis, BCG can induce hyperplasia of the reticuloendothelial system and activation of macrophages in mice. Therefore, these data revealed that BCG vaccination can exert non-specific protective effects for the prevention of diseases other than tuberculosis. Medicinal doses of BCG may be considered a new approach to the treatment of helminth infections.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139229990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present report describes the finding of a worm in the toilet bowl by a patient from Brazil, who thought he had expelled it in his feces. The gross analyses in a clinical laboratory reveal the worm was different from other macroscopic organisms routinely identified, and the laboratory staff requested assistance in an academic laboratory specialized in helminthology. After preliminary analysis in a stereomicroscope, the supposed human worm was identified as an oligochaete annelid (earthworm). The patient was contacted to investigate a possible case of pseudoparasitism. However, we were informed that the organism had been collected in a toilet bowl from a rural environment where the untreated water comes from a cistern indicating our finding was circumstantial. The methodology revisited herein allowed a quick microscopic analysis of easy-to-view morphological structures, which are useful to separate oligochaete annelids from helminths and can prevent misdiagnosis in similar situations. We discuss the overly restricted view on human parasites by health professionals in collecting clinical history and laboratory analysis, providing some epistemological insights on the necessary interdisciplinarity between parasitology and other basic knowledge with health practice.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"69 1","pages":"31-36"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41102425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being one of the main components of the diet of various fish species, it plays an important role in the circulation of different parasite species, including the nematodes of the Anisakidae. Capelin is also extensively caught and used for human food, and has become increasingly available to consumers in Poland. Thirty six capelin specimens, smoked fish bought at a store in Gdynia, were examined for the presence of Anisakidae. Ten specimens of nematode (Anisakis simplex, Contracaecum sp.) were found in eight fish. The overall prevalence for the fish was 22.2%, with a mean intensity of 1.3 (range 1-3). Despite its widespread acquisition and use, capelin has been the subject of few parasitological analyses. Our findings indicate that it is a typical host of Anisakidae nematodes, a species of great zoonotic importance. While dead nematode specimens found in smoked fish do not pose a direct threat to humans as parasites per se, they can cause food allergies. It seems, therefore, that fish intended for consumption should be the subject of constant parasitological monitoring, linked to food quality control.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"69 1","pages":"43-47"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41102255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
