Abstract
Sixteen percent of California ground squirrels (Spermophilus beecheyi) were found to be shedding an average of 53,875 Cryptosporidium parvum oocysts/g of feces. Male squirrels had a higher prevalence and higher intensity of s hedding than did female squirrels. The majority of C, parvum isolates match ed a bovine-murine genotype, with a few isolates resembling a porcine genot ype, Higher intensities of shedding by males may enhance dissemination and genotypic mixing of this protozoa given males' proclivity to disperse to no nnatal colonies.
