Apart from a single record in a shark, there have been no published studies conducted on Giardia genotypes in fish. The present study investigated the prevalence of Giardia in cultured fingerlings (n=227), wild freshwater (n=227) and wild marine/estuarine species (n=255) of fish in Western Australia by PCR amplification at the 18S rRNA, glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi) and beta-giardin (bg) loci. Results revealed a low prevalence of Giardia, 3.8% (27/709), in fish hosts. The zoonotic Giardia species, Giardia duodenalis assemblages A, B as well as G. duodenalis assemblage E and Giardia microti were detected. The identification of zoonotic species of Giardia highlights the public health importance of investigating parasites within fish host species.
