A century later, in 2016, three independent publications renewed interest by reporting the first genetic sequences of ungulate <em>Plasmodium</em> from different host species and continents.

Conversely, in captive chimpanzees, precipitation was negatively associated with <em>Entamoeba</em> sp. and Strongylida fam. gen. Soil surface temperature was inversely correlated with the presence of <em>Balantioides coli</em>, <em>Entamoeba</em> sp., and <em>Mammomonogamus</em> sp. in the semi-captive group. No significant associations were detected between soil water content and parasite occurrence. A Spearman rank correlation analysis revealed a strong positive, though non-significant, relationship between parasite prevalence in soil samples and in captive chimpanzees (ρ = 0.82; p = 0.089).</div></div>","PeriodicalId":54278,"journal":{"name":"International Journal for Parasitology-Parasites and Wildlife","volume":"27 ","pages":"Article 101101"},"PeriodicalIF":2.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307988","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}
