Abstract:

Giardia duodenalis is a widespread intestinal protozoan that can infect humans and animals, both domestic and wild. Independent of host, infections present with the same symptoms. However, based on host specificity, Giardia isolates have been grouped into genotypes A to G. Parasites of assemblage A and B are known to infect humans, in addition to primates and a wide variety of mammals. To evaluate the genotypes of different Giardia present among other animals, fecal samples from humans, dogs, cats and southern brown howler monkeys (Alouattaclamitans) from the Southeast and South regions of the Brazil were characterized based on the β-giardin gene. The samples were analyzed by sequencing of the Nested-PCR products. The A1 and A2 subgenotypes were detected in human, dogs, cats and monkeys. Cysts of assemblage B, C and D have not been found in any isolates studied. 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. Therefore, these results highlight a potential public health problem due to the epidemiological and molecular evidence for anthropozoonotic transmission.
