title: Giardiasis as zoonosis: between proof of principle and paradigm in the Northwestern region of São Paulo State, Brazil.
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.
  
  
  METHODS
  The samples were analyzed by sequencing of the Nested-PCR products.
  
  
  RESULTS
  The 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.
  
  
  CONCLUSIONS
  These results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity.
