Occurrence of blastocystis spp. In domestic animals in triângulo mineiro area of Brazil

Abstract

Introduction: Currently, there are few studies regarding Blastocystis epidemiology. This study aimed to evaluate the occurrence of Blastocystis in animals in Uberaba, Brazil. Methods: Fecal samples were examined by parasitological methods and screened for Blastocystis by polymerase chain reaction. Results: Blastocystis spp. were observed in pigs, sheep, cattle, and dogs. Blastocystis polymerase chain reaction was positive in 14/22 samples positive by parasitological methods. Conclusions: The occurrence of Blastocystis in animals is high, with a predominance of subtype 1 in the region. This is the first study conducted in Brazil showing the genetic profile of Blastocystis isolated from animals.
