neutralization-sensitive epitopes are conserved among geographically diverse isolates of cryptosporidium parvum.isolates of cryptosporidium parvum from new york, florida, brazil, mexico, and peru were examined for the presence of two sporozoite surface epitopes originally identified in an iowa isolate by neutralizing monoclonal antibodies (mabs) 18.44 and 17.41. immunofluorescence microscopy and immunoblotting demonstrated the presence of both epitopes on all isolates. incubation of deae-cellulose-purified sporozoites of the new york, florida, brazil, and mexico isolates with mab 18.44 or 17.41 significan ...19921372299
outbreak of cryptosporidiosis at a day camp--florida, july-august 1995.on july 27, 1995, the alachua county public health unit (acphu) in central florida was notified of an outbreak of gastroenteritis among children and counselors at a day camp on the grounds of a public elementary school. this report summarizes the outbreak investigation, which implicated cryptosporidium parvum as the causative agent and underscores the role of contaminated water as a vehicle for transmission of this organism.19968618545

prevalence of cryptosporidium species and genotypes in mature dairy cattle on farms in eastern united states compared with younger cattle from the same locations.feces collected from 541 milking cows on two dairy farms each in vermont, new york, pennsylvania, maryland, virginia, north carolina, and florida were examined for the presence of cryptosporidium oocysts. oocysts were concentrated from 15 g of feces from each cow and dna was extracted. a two-step nested pcr protocol was used to amplify an 830 base pair fragment of the ssurrna gene. pcr-positive products were purified and sequenced. pcr-positive findings were obtained from cows in all seven state ...200717287086
