geographical variation in 18s rrna gene sequence of cryptosporidium parvum.	using 18s rrna as a probe, an ecor1 fragment containing 1507 nt of 18s rrna from c. parvum was identified, cloned and sequenced. comparison of this sequence with the partial sequence of the small subunit rrna of cryptosporidium published by johnson, fielke, lumb & baverstock (international journal for parasitology 20: 141-147, 1990) and 1516 bp of the 18s rrna nucleotide sequence of c. parvum published by cai, collins, mcdonald & thompson (biochimica et biophysica acta, 1131: 317-320, 1992) reve ...	1994	8026912
prevalence of giardia and cryptosporidium and characterization of cryptosporidium spp. isolated from wildlife, human, and agricultural sources in the north saskatchewan river basin in alberta, canada.	the environmental distribution of giardia spp. and cryptosporidium spp. is dependent upon human, agricultural, and wildlife sources. the significance of each source with regard to the presence of parasites in the environment is unknown. this 2-year study examined parasite prevalence in human sewage influent, wildlife, and agricultural sources associated with the north saskatchewan river basin in alberta, canada. fecal samples were collected from cow-calf, dairy, and hog operations in the watersh ...	2002	12166680
prevalence and infection pattern of naturally acquired giardiasis and cryptosporidiosis in range beef calves and their dams.	the prevalence and infection pattern of naturally acquired giardiasis and cryptosporidiosis in 20 ranch raised beef calves and their dams from birth to weaning was determined. rectal fecal samples were collected from calves at 3 days of age and weekly thereafter; cows' fecal samples were collected at the time of calving, 1 week later and four times during the summer grazing period. blood samples were collected from the calves at 3 days of age to determine igg(1) concentrations. giardia lamblia c ...	2003	12781473
