occurrence of giardia and cryptosporidium in pigs on prince edward island, canada.	in a cross-sectional study of 633 pigs from 21 herds on prince edward island, canada (pei), the prevalence of infection with cryptosporidium and giardia, and the genotypes and species of isolates were determined in order to establish the zoonotic potential of pigs in this region. as determined by direct immunofluorescence microscopy (dfa), 18 herds (86%) and 163 animals (26%; 95% ci: 22-29%) tested positive for cryptosporidium, while just 3 herds (14%) and 6 animals (1%; 95% ci: 0.4-2%) tested p ...	2011	21868167
occurrence of cryptosporidium and giardia on beef farms and water sources within the vicinity of the farms on prince edward island, canada.	the objectives of this study were to determine the prevalence and assemblages of giardia and species of cryptosporidium on beef farms in prince edward island (pei), canada, including the water sources associated with the farms, and to determine risk factors for infection of cattle with these parasites. twenty beef farms were selected based on the presence of surface water<500m from the barn. prevalence was determined by direct immunofluorescence microscopy, while genotyping and species determina ...	2011	22112978
prevalence and genotypes of giardia duodenalis in dairy and beef cattle in farms around charlottetown, prince edward island, canada.	prevalence of giardia duodenalis in dairy and beef cattle on farms around charlottetown, prince edward island (canada) was determined by analyzing feces using direct immunofluorescence antibody microscopy. genotypes were determined by 16s-rrna sequencing. fecal samples (n = 892) were collected from adult cattle in dairy tie-stall, dairy free-stall, and beef herds (10 herds each), and from calves (n = 183) from 11 dairy farms. prevalence rates were 38% and 51% in cows and calves, respectively. gi ...	2011	22379195
