Abstract
Objective
In order to evaluate the potential zoonotic transmission of Giardia duodenalis, isolates from humans and dogs in the Northwestern region of the São Paulo State, Brazil were characterized based on the β-giardin gene.
MethodsThe samples were analyzed by sequencing of the Nested-PCR products.
ResultsThe A1 and A2 subgenotypes were detected in human and dogs. Cysts of assemblage B, C and D have not been found in any isolates studied.
ConclusionsThese results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity.
