Prevalence and molecular characterisation of Cryptosporidium and Giardia species in pre-weaned sheep in Australia.

Molecular characterization of Cryptosporidium and Giardia in pre-weaned calves in Western Australia and New South Wales.

A total of 364 fecal specimens from randomly selected pre-weaned calves, aged up to 4 months, from 5 different farms in the south of Western Australia and 1 farm from New South Wales were screened for the presence of Cryptosporidium and Giardia using PCR. There were substantial differences in prevalence between the farms and the overall prevalence was 22.3% (81/364) and 26.9% (98/364) respectiv...

Molecular characterization of Cryptosporidium and Giardia in pre - weaned calves 1 in Western Australia and New South Wales

Prevalence and molecular characterization of Cryptosporidium and Giardia species and genotypes in sheep in Maryland.

In the United Kingdom and Australia sheep have been implicated as sources of Cryptosporidium and Giardia that infect humans, but no such studies have been conducted in North America. Therefore, a study was undertaken to investigate the prevalence of these parasites in sheep on a farm in Maryland. Feces were collected from 32 pregnant ewes 1, 2, and 3 days after parturition and from each of thei...

Molecular characterisation of Cryptosporidium and Giardia in cats (Felis catus) in Western Australia.

Little is known of the prevalence of Cryptosporidium and Giardia in domestic cats in Western Australia and their potential role as zoonotic reservoirs for human infection. In the present study, a total of 345 faecal samples from four different sources were screened for the presence of Cryptosporidium and Giardia by PCR and genotyped by sequence analysis. Oocyst numbers and cyst numbers for Cryp...

Giardia genotypes in pigs in Western Australia: prevalence and association with diarrhea.

Little is known of the prevalence of Giardia species and genotypes in pre- and post-weaned domestic pigs. In the present study, a total of 297 pig faecal samples were screened for the presence of Giardia by PCR and genotyped. An overall prevalence of 31.1% (90/289) (25.8, 36.5 CI) was detected. Giardia was detected in 17% (23/123) (11.8-25.6 CI) of pre-weaned piglet faecal samples and 41% (64/1...
