Toxoplasma gondii in a Remote Subsistence Hunting-Based Indigenous Community of the Peruvian Amazon Menajovsky, María Fernanda Espunyes, Johan Ulloa, Gabriela Calderon, Maritza Diestra, Andrea Malaga, Edith Muñoz, Carmen Montero, Stephanie Lescano, Andres G. Santolalla, Meddly L. Cabezon, Oscar Mayor, Pedro Producció Animal Sanitat Animal Toxoplasma gondii is a ubiquitous zoonotic protozoan parasite that infects a wide variety range of warm-blooded animals. This study describes the epidemiological scenario of T. gondii in an indigenous community that relies on subsistence hunting in a well-conserved and isolated area of the Peruvian Amazon. The high seropositivity against T. gondii in humans (83.3% IgG and 6.1% IgM), wild mammals (30.45%, 17 species), peri-domestic rodents (10.0% Rattus sp.), and domestic animals (94.1% dogs and 100% cats) indicates the existence of a sylvatic cycle in the community under study. Individual age was found to be positively associated with IgG detection against T. gondii but not with IgM. It is estimated that each family consumed 5.67 infected animals per year with terrestrial species having higher infective rates than arboreal species. The main risk factors included improper handling and cooking of wild meat, poor hygiene practices, and feeding uncooked offal to domestic animals. This scenario results in a continuous process of infection and reinfection within the indigenous community with cats, dogs, and peri-domestic animals becoming infected through the ingestion of infected raw viscera. Our results emphasize the need to promote safe food handling practices and disposal of waste materials from hunted animals in such communities. 2025-10-22T11:18:13Z 2025-10-22T11:18:13Z 2025-10-22T11:18:13Z 2024-04-26 info:eu-repo/semantics/article Menajovsky, María Fernanda, Johan Espunyes, Gabriela Ulloa, Maritza Calderon, Andrea Diestra, Edith Malaga, Carmen Muñoz, Stephanie Montero, Andres G.
