Abstract

A total of 289 pig faecal samples were collected from pre-weaned and post-weaned piglets and sows from 1 indoor and 3 outdoor piggeries located in the south-west region of Western Australia and screened at the 18S rRNA locus for the presence of Cryptosporidium. An overall prevalence of 22.1% (64/289) was identified. Cryptosporidium was more prevalent in post-weaned animals (p < 0.05); 32.7% (51/156) versus 10.6% (13/123) for pre-weaned animals. Sequence analysis identified Cryptosporidium suis in all pre-weaned isolates genotyped (7/13). In post-weaned pigs that were genotyped (n = 38), the non-zoonotic Cryptosporidium species, pig genotype II was identified in 32 samples and C. suis in 6 samples. The zoonotic species Cryptosporidium parvum was not detected, suggesting that domestic pigs do not pose a significant public health risk. Pig genotype II was significantly (p < 0.05) associated with 'normal' stools, indicating an asymptomatic nature in the porcine host.
