Abstract
ABSTRACT
A total of 430 avian-derived fecal specimens were randomly collected from selected Western Australian commercial aviaries, poultry farms, hatcheries, wildlife parks, and the Perth Zoo and screened for the presence of
Cryptosporidium
by PCR. Of these, 27
Cryptosporidium
-positive isolates were detected, characterized, and compared with 11 avian-derived isolates from the Czech Republic at the 18S rRNA and actin gene loci. Sequence and phylogenetic analysis identified four genetically distinct genotypes, avian genotypes I to IV, from various avian hosts. In addition, the host range for
Cryptosporidium galli
was extended.
Cryptosporidium muris
and
Cryptosporidium andersoni
were also identified in a tawny frogmouth and a quail-crested wood partridge, respectively.
