title: Prevalence and genotype of Giardia duodenalis in dairy cattle from Northern and Northeastern part of Thailand.
abstract: The aims of this study were to determine prevalence and genotype of Giardia duodenalis in feces of dairy cattle from the northern part and the northeastern part of Thailand. A total of 900 fecal samples were collected directly from rectum and examined by using zinc sulphate centrifugal flotation technique and polymerase chain reaction (PCR). The overall prevalence of G. duodenalis in dairy cows was 5.0 % (45/900) by zinc sulphate centrifugal flotation and 6.0 % (54/900) by PCR. Genotypes of G. duodenalis found in this study were Assemblage AI and E. The results indicated that dairy cattle may act as a potential risk of Giardia transmission among animals and humans (especially Assemblage AI).
