Resum
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.
