Cryptosporidium parvum was detected and genotyped among 2,446 children of whom 1,779 (72.7%) had diarrhea, and 667 (27.3%) were age- and sex-matched controls. Of the 1,779 children with diarrhea, 532 (29.9%) had persistent (&gt; 14 days) diarrhea and 1,247 (70.1%) had acute diarrhea. Overall, 444 (25.0%) of the 1,779 children with diarrhea had C. parvum, compared with only 57 (8.5%) of the 667 children without diarrhea (chi2 = 80.2, P &lt; or = 0.0001). Within this group of infected children, 72.8% were infected with genotype 1, 18.4% with genotype 2, and 4.1% with a mixture of both genotypes, and 4.1% isolates were either unclassified or C. meleagridis. The prevalence was highest during the rainy months of April to June. Of the 532 children with persistent diarrhea, 166 (31.2%) had C. parvum compared with 278 (22.3%) of the 1,247 children with acute diarrhea (chi2 = 15.8, P &lt; or = 0.0001). There was a significant association between C. parvum and malnutrition including stunting, being underweight, and wasting. Unfavorable outcome (death or failure to resolve within 14 days) occurred in 139 (72.8%) of the 191 children with C. parvum, and in only 65.1% of the 545 without (odds ratio = 1.117, 95% confidence interval = 1.005-1.243, P = 0.05), Of the 191 children with C. parvum, 24 (12.6%) died, compared with 34 (6.2%) of the 545 without C. parvum (P = 0.005). Mortality rates were higher among children with severe dehydration and persistent diarrhea, and in stunted or underweight children infected with C. parvum. Among Ugandan children, cryptosporidiosis, which remains untreatable, is frequently associated with diarrhea and other serious and unfavorable consequences.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12887032?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Okhuysen, Pablo C</style></author><author><style face="normal" font="default" size="100%">Rich, Stephen M</style></author><author><style face="normal" font="default" size="100%">Chappell, Cynthia L</style></author><author><style face="normal" font="default" size="100%">Grimes, Kevin A</style></author><author><style face="normal" font="default" size="100%">Widmer, Giovanni</style></author><author><style face="normal" font="default" size="100%">Feng, Xiaochuan</style></author><author><style face="normal" font="default" size="100%">Tzipori, Saul</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Infectivity of a Cryptosporidium parvum isolate of cervine origin for healthy adults and interferon-gamma knockout mice.</style></title><secondary-title><style face="normal" font="default" size="100%">J Infect Dis</style></secondary-title><alt-title><style face="normal" font="default" size="100%">J.

After exposure to 100-3000 oocysts, 16 volunteers recorded, for a duration of 6 weeks, the number and form of stools that they passed and any symptoms that they experienced. Oocyst excretion was assessed by enzyme-linked immunosorbent assay and direct immunofluorescence assay. Eleven subjects (69%) became ill, and 8 subjects (50%) shed oocysts in stool. The median duration of illness was 169 h, and the median number of unformed stools passed was 24. The duration and intensity of symptoms were more severe than were those associated with previously studied isolates. The median infectious dose was estimated to be 300 oocysts for humans and 1 oocyst for the GKO mouse model. The Moredun isolate was more pathogenic than the reference GCH-1 isolate. The GKO mouse model of cryptosporidiosis is useful for discerning isolate-specific differences in pathogenicity.</style></abstract><issue><style face="normal" font="default" size="100%">9</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12001050?dopt=Abstract</style></custom1></record></records></xml>
