Abstract

ABSTRACT: Family Tayassuidae in the suborder Suina include two species of peccaries in Brazil: the white-lipped peccary (Tayassu pecari) and the collared peccary (Pecari tajacu). These animals share common pathogens with domestic swine (Sus scrofa); however, their role as potential carrier remains unclear. This study focused on detecting the prevalence of influenza A antibodies in Tayassu pecari and Pecari tajacu from commercial rearing farms from two states in Brazil. A set of 50 blood samples from Pecari tajacu and 55 from Tayassu pecari were analyzed using a commercial indirect ELISA in order to investigate anti influenza A antibodies. Pecari tajacu samples presented 22% (11/50) of seropositivity for the virus. Serological surveillance is an important tool to identify the presence and the spread of the influenza virus in feral pigs.

Highlights

RESUMO: A família Tayassuidae pertencente a subordem Suina e compreende duas espécies presentes no Brasil: Queixada (Tayassu pecari) e o Caititu (Pecari tajacu)
Previous studies reported the presence of Porcine Circovirus, Herpesvirus, Mycoplasma hyopneumoniae and Pasteurella multocida in Pecari tajacu and Tayassu pecari populations (CASTRO et al, 2014)
In Brazil, wild boars samples revealed a human-like H1N2 influenza virus, with genes derived from the H1N1 pdm09 (BIONDO et al, 2014)

Summary

Introduction

RESUMO: A família Tayassuidae pertencente a subordem Suina e compreende duas espécies presentes no Brasil: Queixada (Tayassu pecari) e o Caititu (Pecari tajacu). Peccaries and pigs are able to be infected by several common pathogens, once they diverged one million years ago from a common ancestor (COUTINHO et al, 2012) and previous studies detected peccaries as potential reservoirs of infectious diseases for domestic pigs and wild swine (Sus scrofa) (HERRERA et al 2008; COUTINHO et al 2012).
