Current knowledge on the prevalence and genotypes of Cryptosporidium in fishes is still
limited. This study investigated the prevalence of Cryptosporidium species in 171
ornamental fishes, belonging to 33 species, collected from 8 commercial aquariums around
Perth, Western Australia. All samples were screened by nested PCR targeting the 18S rRNA
locus. A total of 6 positives were identified by PCR at the 18S locus from 4 different species
of fishes (red eye tetra, Moenkhausia sanctaefilomenae; gold gourami, Trichogaster …
