Giardiasis in urban and rural Amazonas, Brazil is driven by zoonotic and cosmopolitan A and B assemblages.

ABSTRACT:

Background

Giardia duodenalis is a protozoan parasite that infects humans and other mammals and causes giardiasis worldwide. Giardia is genotyped into eight assemblages (A-H), with assemblages A and B considered zoonotic.

Objectives

The aim of this study was to determine the assemblages of G. duodenalis from individuals living in rural and urban areas of the Amazonas State.

Methods

103 human faecal specimens microscopically positive for the presence of Giardia obtained from four municipalities in Amazonas and four animal faecal specimens were genotyped based on the sequences of two genes, triosephosphate isomerase (TPI) and β-giardin (BG).

Findings

In humans, assemblage A was the most represented with the identification of sub-assemblages AI, AII and AIII based
