title: Effect of age and sex on the prevalence of intestinal parasitism in cats.
abstract: The effects of age, sex, and neutering on the prevalence of feline intestinal parasitism were evaluated by fecal examination of 1,294 cats admitted to the University of Missouri Veterinary Teaching Hospital for the 3-year period, 1974 to 1976. Approximately 37% of the cats examined had 1 or more parasite species. Ascarids were the most commonly encountered parasites (24.4%), with coccidia (6.7%), hookworms (6.4%), tapeworms (5.2%), and trichurids (2.6%) being less frequently observed. Most parasitisms were monospecific. Considering age categories from birth to 5 years, patent ascarid infections were less prevalent in cats greater than 6 months old, whereas hookworm infections were most prevalent in cats 1 to 5 years old; trichurids (whipworms and capillarids) were most often found in cats greater than 6 months old; and coccidia were found with uniform frequency in cats of all age categories. Sex seemed to have no effect on prevalence of parasitism, and the only effect of neutering was on the occurrence of ascarid infection, with spayed females having a prevalance of 14.3%, castrated males, 17.8%, and their intact counterparts, 26%.
