The prevalence of and risk factors associated with the shedding of cryptosporidial oocysts were determined for domestic cats in northeastern Mississippi and northwestern Alabama. Cryptosporidial oocysts were found in a single fecal samples from 30 of 250 cats using a centrifugal concentration technique followed by an immunofluorescent assay. The odds of a cat shedding oocysts were increased when another cat shedding oocysts was present in the household. Logistic regression analysis showed only concurrent shedding of Giardia cysts to be significantly associated with the presence of Cryptosporidium oocysts in the feces. Oocysts from 12 cats were successfully genotyped, based on sequencing of a fragment of the 18S rRNA gene, all isolates were Cryptosporidium felis.
