Distribution of Blastocystis subtypes isolated from humans from an urban community in Rio de Janeiro, Brazil.

ABSTRACT:

Background

Blastocystis is a cosmopolitan protist parasite found in the human gastrointestinal tract and is highly prevalent in developing countries. Recent molecular studies have revealed extensive genetic diversity, which has been classified into different subtypes (STs) based on sequence analysis of small subunit ribosomal RNA gene. Blastocystis is one of the most common fecal parasites in Brazil, but the diversity of subtypes remains unknown in the country. This study aimed to determine the distribution of Blastocystis STs in an urban community in Duque de Caxias, Rio de Janeiro, Brazil.

Methods

A total of 64 stool samples positive for Blastocystis in Pavlova's medium were subtyped by PCR and sequenced using primers targeting the small subunit rRNA gene, in addition to p
