The assemblage of 37 Giardia intestinalis samples was determined, 19 obtained from puppy feces, 12 from stools of different human subjects under 3 years of age and 6 from axenic culture. The assemblages were classified according to the restriction pattern of beta-giardin gene with Hae III enzyme. Results showed that dog assemblages were grouped AI (52.6%) and AII (47.4%), while 41.7% human samples belonged to genotype AI and 58.3% to genotype AII. All axenic cultures belonged to assemblage AI; types AI and AII were both found in dog and human feces by Hae III restriction enzyme assay, suggesting a similarity between human and dog parasites. These results suggest that domestic animals infected with Giardia could produce cysts potentially infective for humans.
