The city, which previously provided only chlorination for their surface \nwater sources added filtration in addition to chlorination. To assess whether <jats:italic>Cryptosporidium<\/jats:italic> \ninfections rates declined following filtration, we tested serological responses to 15\/17-kDa and \n27-kDa <jats:italic>Cryptosporidium<\/jats:italic> antigens among 107 community college students 1 month before and \n225 students 5 months after filtration. Results suggest that levels of <jats:italic>Cryptosporidium<\/jats:italic> infections \ndid not decline following water filtration. However, seasonal changes in other exposures may \nhave confounded the findings. Swimming in a lake, stream or public pool and drinking \nuntreated water from a lake or stream predicted a more intense response to one or both \nmarkers. Residence in the city, not drinking city tap water or drinking bottled water, gender, \ntravel or exposure to pets, young pets, diapers or a household child in day care were not found \nto be predictive of more or less intense serological responses for either the 15\/17-kDa and \n27-kDa antigen.<\/jats:p>","DOI":"10.1017\/s0950268899004148","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:23:42Z","timestamp":1027776222000},"page":"87-92","source":"Crossref","is-referenced-by-count":11,"title":["A serological survey of college students for antibody to \n<i>Cryptosporidium<\/i> before and after the introduction of a new \nwater filtration plant"],"prefix":"10.1017","volume":"125","author":[{"given":"F.
