The aim of this study was to determine the seroprevalence of the Toxoplasma gondii parasite in goats from the department of Piura, Peru. In total, 362 serum samples were evaluated using a commercial indirect ELISA kit, which reveals the presence of IgG anti-T. gondii antibodies. The real seroprevalence was 26.29% (95% CI: 21.74 - 30.84%). The confidence intervals (95% CI) evidenced a significant difference (p<0.05) in the seropositive goats in relation to the altitudinal floor variable (0-500 vs 500-2500 m), while no significant difference was evidenced regarding the age group variable (<1, 1-3 and >3 years). The Odds Ratio (OR) between the sero-reactor animals and the altitudinal floor variable yielded a value of 0.37 (95% CI: 0.20 - 0.69), indicating that the altitude 0-500 m was a protective factor for toxoplasmosis infection in relation to 500-2500 m.

The study aimed to determine the prevalence of zoonotic liver helminths and their histopathological characterization in rodents (Rattus spp.) from a zoo, pig farms and food markets in Lima, Perú. The morphometric parameters of each rodent were recorded to determine the age and identify the species, computing a total of 267 animals. The handling and the capture methodology were carried out according to the biosafety standards established by the Center for Infectious Diseases and Prevention of Atlanta. Livers were macroscopically evaluated for lesions. For diagnostic confirmation by histopathology, samples were taken from the right lateral lobe of all the livers together with other areas that showed damage in search of tissue lesions and inflammatory response related to the presence of the parasites. The pathological analysis determined a prevalence of 3.74% of Cysticercus fasciolaris in ...
