Cysts of Entamoeba coli were the most frequently found in this study (50%), followed by Hymenolepis diminuta eggs (27.6%), Iodamoeba butschllii cysts (5.6%), Ascaris lumbricoides eggs (5.6%), Taenia species eggs (5.6%) and hookworm eggs (5.6%). The highest positivity rates were found in the samples drawn from the cafeteria's eating table.

https://pubmed.ncbi.nlm.nih.gov/29972467/ > The aim of this study was to establish the prevalence of Schistosoma mansoni in indigenous Maxakali villages, evaluating the TF-Test® performance for diagnosis compared to the Kato-Katz technique. Stool samples from 545 individuals were processed by the TF-Test® (1 sample) and Kato-Katz (1 slide). The positivity rate for S. mansoni by Kato-Katz was 45.7%. The rate by the TF-Test® was 33.2%, and 51.9% by the combined parasitological techniques. The amplitude of parasite load was 24 to 4,056 eggs per gram of feces (epg), with a geometric mean of 139 epg.
