The aim of this study was to identify gastrointestinal parasites present in wild yellow-tailed woolly monkey (Lagothrix flavicauda) in the Corosha district, Amazonas department, Peru. Twenty fecal samples were collected immediately after defecation. Each sample was separated into two portions to be fixed in 10% formalin at 65 ºC and in polyvinyl alcohol (PVA). The samples were analyzed using the Direct, Ritchie, Sheather Sugar, Gomori trichrome staining and modified Ziehl-Neelsen staining methods. The gastrointestinal parasites found were four nematodes (Capillaria sp, Ancylostoma sp, Strongyloides cebus, Strongyloides sp), one cestode (Paratriotaenia oedipomidatis), one acantocephalus (Prosthenorchis elegans) and three protozoa (Entamoeba coli, Cryptosporidium sp, Coccidia sp. Coccidia sp is a new genus reported for Lagothrix flavicauda.

Las ranas del género Telmatobius están entre las especies de fauna silvestre más traficadas en Perú debido a que son colectadas para ser usadas como fuente alimenticia o porque les atribuyen propiedades medicinales. Entre 2012 y 2013, el Laboratorio de Vida Silvestre de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad Peruana Cayetano Heredia recibió y mantuvo cerca de 400 ranas altoandinas (Telmatobius culeus) de decomisos hechos en el Mercado de La Parada en La Victoria, Lima, por la Administración Técnica Forestal y de Fauna Silvestre de Lima. En este estudio se recopila información producto del trabajo en la rehabilitación y mantenimiento en cautiverio de estos ejemplares.
