enzyme-linked immunosorbent assay for the detection of cryptosporidium parvum igg in the serum of cats.	the objective was to develop an enzyme-linked immunosorbent assay (elisa) for the detection of cryptosporidium parvum igg in the serum of cats. the elisa was an indirect elisa using soluble c. parvum oocyst antigens and a peroxidase-labeled anti-feline igg secondary antibody. sera from cats with toxocara felis, giardia spp., aelurostrongylus abstrusus, isospora felis, isospora rivolta, toxoplasma gondii, or taenia spp. infections were assayed in specificity studies. following optimization, the e ...	1997	9379309

prevalence of enteric pathogens in dogs of north-central colorado.	to evaluate the prevalence of enteric pathogens in dogs of north-central colorado, fecal samples were obtained from client-owned dogs presented to the veterinary teaching hospital at colorado state university for evaluation of acute small-bowel, large-bowel, or mixed-bowel diarrhea (n=71) and from age-matched, client-owned, healthy dogs (n=59). infectious agents potentially associated with gastrointestinal disease were detected in 34 of 130 (26.1%) fecal samples. agents with zoonotic potential w ...	2003	12549614
manufacturer's recall of rapid cartridge assay kits on the basis of false-positive cryptosporidium antigen tests--colorado, 2004.	the colorado department of public health and environment (cdphe) has determined that a fourfold increase in the number of reported cryptosporidiosis cases in colorado during january-february 2004 might be attributed primarily to false-positive test results. since january 1, 2004, a total of 13 in-state cases and one out-of-state case were reported to cdphe. during the previous 7 years, an average of three cases were reported during january-february. in eight of 14 patients, rapid testing was per ...	2004	15017377
environmental load of cryptosporidium parvum oocysts from cattle manure in feedlots from the central and western united states.	the first step in assessing the risk of water contamination by cryptosporidium parvum oocysts from feedlot cattle (bos taurus) production systems is to quantify the number of c. parvum oocysts present in the fecal material deposited by feedlot cattle. our primary objective for this project was to estimate the daily environmental load of c. parvum oocysts in fecal material deposited by feedlot cattle from across the central and western usa. our secondary goal was to genotype isolates of c. parvum ...	2006	16391291
baylisascaris procyonis in raccoons (procyon lotor) from eastern colorado, an area of undefined prevalence.	baylisascaris procyonis is a zoonotic parasite that has been documented in raccoons throughout much of the united states; however, no published information on its occurrence is available for the transition zone from the great plains to the rocky mountains. because this parasite can cause neural larva migrans and diffuse unilateral subacute neuroretinitis in humans (as well as other hosts), a more complete understanding of the distribution of this parasite seems warranted for public health reason ...	2011	22119387
