recovery of cryptosporidium oocysts and giardia cysts from source water concentrates using immunomagnetic separation.immunomagnetic separation (ims) procedures for the simultaneous isolation of cryptosporidium oocysts and giardia cysts have recently become available. we validated dynal's gc-combo ims kit using source water at three turbidity levels (5000, 500 and 50 nephelometric turbidity units [ntu]) obtained from different geographical locations and spiked with approximately 9--11 (oo)cysts per ml. mean recoveries of cryptosporidium oocysts and giardia cysts in deionized water were 62% and 69%, respectively ...200111311391
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 ...200616391291
