Abstract

Morro do Diabo State Park (MDSP) is a significant remnant of the Atlantic Rain Forest in Brazil and is surrounded by rural properties. In that area, wild and domestic animals and humans are in close contact, which facilitates the two-way flow of infectious diseases among them. We assessed endoparasites in domestic livestock from all rural properties surrounding MDSP. There were sampled 197 cattle, 37 horses, 11 sheep, 25 swine, 21 dogs, one cat and 62 groups of chickens from 10 large private properties and 75 rural settlements. Eimeria spp. was present in almost all hosts, excepted in horses, dogs and cats. Giardia cysts were present only in cattle. Nematodes were found in swine, ruminants and horses in high prevalence. Ancylostoma, Toxocara and Sarcocystis were found in dogs. Chickens were found with coccidia, Ascaridida and Capillaria spp.. These parasites can cause malnutrition and reproductive disorders for their hosts. Strategies to prevent and control the spread of endoparasites can improve wildlife, animal and human health in this area.

Highlights

Morro do Diabo State Park (MDSP) is the last significant remnant of the Atlantic Rain Forest in western São Paulo State, Brazil, where only 1.8% of the original natural vegetation remains
Fecal samples from domestic animals raised as pets or for subsistence were collected from all rural properties directly surrounding the MDSP border
These rural properties are divided into 10 large private properties and 75 small rural settlements and are all located around MDSP in Teodoro Sampaio Municipality of São Paulo State, Brazil (Figure 1)

Summary

Introduction

Morro do Diabo State Park (MDSP) is the last significant remnant of the Atlantic Rain Forest in western São Paulo State, Brazil, where only 1.8% of the original natural vegetation remains. The Atlantic Rain Forest is considered a biodiversity hotspot (GALETTI & SAZIMA, 2006) This forest is surrounded by rural properties, some of which are owned by low-income farmers (settlers) who survive on subsistence agriculture (SEVÁ et al, 2010). These properties make up a settlement that originated from the Landless Workers Movement. Some parasites can affect different host species. Endoparasites, such as worms and protozoans, have great impacts on public and animal health and wildlife conservation around the world, mainly in developing countries. Research has reported 11 previously unidentified endoparasite hosts in wild animals from different biomes in Brazil (RAMOS et al, 2016)
