Giardia trophozoites have both highly dynamic and highly stable MT organelles, including the ventral disc, eight flagella, the median body and the funis. The ventral disc, an elaborate MT organelle, is essential for the parasite's attachment to the intestinal villi to avoid peristalsis. Giardia's four flagellar pairs enable swimming motility and may also promote attachment. They are maintained at different equilibrium lengths and are distinguished by their long cytoplasmic regions and novel extra-axonemal structures. The functions of the median body and funis, MT organelles unique to Giardia, remain less understood. In addition to conserved MT-associated proteins, the genome is enriched in ankyrins, NEKs, and novel hypothetical proteins that also associate with the MT cytoskeleton. High-resolution ultrastructural imaging and a current inventory of more than 300 proteins associated with Giardia's MT cytoskeleton lay the groundwork for future mechanistic analyses of parasite attachment to the host, motility, cell division, and encystation/excystation. Giardia's unique MT organelles exemplify the capacity of MT polymers to generate intricate structures that are diverse in both form and function. Thus, beyond its relevance to pathogenesis, the study of Giardia's MT cytoskeleton informs basic cytoskeletal biology and cellular evolution. With the availability of new molecular genetic tools to disrupt gene function, we anticipate a new era of cytoskeletal discovery in Giardia.","PeriodicalId":50854,"journal":{"name":"Advances in Parasitology","volume":"107 ","pages":"25-96"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.apar.2019.11.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37697561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A review of the published literature indicated that prevalence of both parasites is declining in more recent studies (post 2000), likely due to changes in animal husbandry as well as use of anthelmintics. Geographically, prevalence was higher in the east (Atlantic), and in more southerly locations, possibly due to more favourable climate conditions for egg survival and development. At northern latitudes and in wild felids and canids in general, the non-zoonotic ascarid Toxascaris leonina appears to outcompete Toxocara spp.; however, T. leonina is rare in domestic cats in Canada. Prevalence of Toxocara spp. was higher in cats than dogs, shelter/rural/remote/feral/stray vs owned animals, and young vs adult animals, as has been observed in many other studies and regions of the world. While the regional prevalences in this review should be interpreted carefully in light of variation in diagnostic methods and study populations, they generally follow the same trends observed in a recent national study of shelter animals. This review is a timely summary of the state of the published knowledge on prevalence of Toxocara spp. in Canada, and highlights knowledge gaps to be addressed, including the northern distributional limits of these species in Canada, the potential for transmission to and from wildlife hosts, and the public health significance of the parasite in the mainstream Canadian population.","PeriodicalId":50854,"journal":{"name":"Advances in Parasitology","volume":"109 ","pages":"641-653"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.apar.2020.01.026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37911901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toxocariasis is the most common helminth infection in many countries. Disease caused by Toxocara can be classified into five clinical forms: generalised, neurological, ocular, covert, and asymptomatic. The clinical pathology of toxocariasis largely depends on the form of infection, the intensity of the infection, the larvae localisation, and the age of the host. Because histological and molecular examination of toxocariasis is limited by difficulties in obtaining material to analyse, clinical diagnosis is often based on nonspecific tests, such as the detection of eosinophilia and hyperimmunoglobulinemia E (Hyper-IgE). Specific analysis uses an initial ELISA test to detect anti-Toxocara IgG and requires confirmation for all positive results via Western blot. This strategy does not distinguish between actual and recent infections, making the monitoring of disease a challenge for clinicians. Additional research will be required to distinguish active disease from the presence of recent infection.","PeriodicalId":50854,"journal":{"name":"Advances in Parasitology","volume":"109 ","pages":"153-163"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.apar.2020.01.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37913131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
