A fecal parasitological study of the population performing artisanal fishing of Terminal Pesquero de Chorrillos (Fishing Terminal of Chorrillos), Province of Lima, Peru, was conducted aiming at determining the prevalence of endoparasites and their relationship with fishing activity. Fecal samples were examined by the Ritchie's Method and the Spontaneous Sedimentation in Tube Technique. The prevalence of endoparasites was 68%. The only pathogenic protozoa found was Giardia intestinalis (syn. G. lamblia) (Lambl, 1859) Kofoid & Christiansen, 1915 with a 16% prevalence. The helminth parasites found included Hymenolepis nana (Culbertson, 1940) and Ascaris lumbricoides (Linnaeus, 1758), both with a 4% prevalence. Commensal parasites found included Endolimax nana (Wenyon & O´Connor, 1917) at a prevalence reaching 40%, followed by Entamoeba coli (Grassi, 1879) with 28% and finally Iod...

The aim of the present work was to determine the predictors of the parasitic ecology of Centrocestus formosanus (Trematoda: Heterophyidae) on Melanoides tuberculata (Caenogastropoda: Thiaridae) in the coastal wetland Los Pantanos de Villa (HCLPV), Lima, Peru. In total, 2532 specimens of M. tuberculata were evaluated in three lagoons: “Las Delicias”, “Mayor”, and “Marvilla”, with different levels of disturbance recorded as “high”, “medium”, and “low”, respectively, during 2009 to 2011. The largest total length (TL) of M. tuberculata occurred in Marvilla. The prevalence of C. formosanus was in sporocyst-redia (18.25%) and cercaria (24.64%). The decreasing order of prevalence for sporocyst-redia and cercaria for the lagoons was Mayor > Marvilla > Las Delicias. The sporocyst-redia presented the highest value in summer and the cercaria recorded it in the spring. ...

The objective of this work was to evaluate the contamination of public parks in the district of Huánuco, Perú with eggs of Toxocara canis. 32 soil samples were taken in each of 11 parks for a total of 352 samples in May and June of 2014. Parks were selected at random. In each park, 2-3 kg soil was collected according to the double “W” method. Flotation with a saturated sugar solution was used. Samples were considered positive when at least one egg of T. canis was found. Of the 11 parks sampled, T. canis eggs were found in 90.9%. Seven parasites were found along with T. canis in the soil. The sequence of parasite prevalence was in the following descending order: T. canis> Strongylus type eggs of Ancylostoma caninum > A. caninum larvae = Blastocystis hominis > Trichuris vulpis= Entamoeba sp. > Capillaria sp. = Balantidium coli. Parasite richness was 2.45 ± 1.21 (1-4) par...
