Documenting the extent of soil contamination by T. gondii oocysts is necessary to prevent infection caused by this protozoan. The aim of our study is to determine the occurrence of T. gondii oocysts in urban soil in Marrakesh, Morocco. A total of 42 soil samples were collected from 9 sites in the urban area of Marrakesh. Oocysts were extracted by the flotation method, and detected by microscopy using both bright-field and UV. The frequency and spatial distribution of T. gondii in soil were analyzed considering the factors that could affect the mode of contamination, such as the presence of cats and the survival conditions of oocysts. All analyzed soil samples from Marrakesh were negative. The results of the present study are correlated to the sensitivity of our detection method as well as the presence of cats, the main reservoir of this parasite. In addition, temperature, moisture, and soil composition can significantly influence oocysts survival, and consequently affect the probability of human contamination through food.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"87 1","pages":"99 - 102"},"PeriodicalIF":0.5,"publicationDate":"2020-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45146877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparison of mean relative positions and intestinal segment use of all 3 helminths revealed no negative interactions among the 3 species. Paulisentis missouriensis appeared entirely unaffected by the presence of either R. canadensis or A. lobatum. Each of the latter 2 species, however, appeared to exhibit some shift toward, rather than away from, the location of P. missouriensis in co-infected hosts. However, the effect size in both cases was small and therefore could be spurious. At higher intensities of co-infecting P. missouriensis, worms of A. lobatum were either distributed far to the anterior or far to the posterior of the intestinal locations occupied by P. missouriensis. This constituted the only evidence in the present investigation for negative interspecific interactions among these 3 frequently co-occurring helminths in this system.","PeriodicalId":50655,"journal":{"name":"Comparative Parasitology","volume":"87 1","pages":"95 - 98"},"PeriodicalIF":0.5,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46025607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
