The Predominance of Giardia duodenalis AII sub-assemblage in young children from Salvador, Bahia, Brazil.

ABSTRACT:

Introduction

Giardia duodenalis is an intestinal protozoan with a high prevalence in children of developing countries. Molecular studies revealed a great genetic diversity of G. duodenalis, with assemblages A and B found mainly in humans. Despite its importance, the information on the molecular epidemiology of human giardiasis is still limited in Brazil.

Objective

To characterize G. duodenalis molecular isolates in children from Salvador, Bahia, Brazil.

Materials and methods

Giardia duodenalis positive fecal samples were obtained from 71 children from two day care centers and 39 users of a clinical analysis laboratory. Samples were analyzed by PCR-RFLP of the glutamate dehydrogenase (gdh) and beta-giardin genes and by the sequencing of beta-giardin.
