RESUMO
Infection rates with Giardia duodenalis and Cryptosporidium spp. were compared among dogs living under different conditions. Stool samples (n = 433) collected from dogs of different ages, gender, living conditions and origin were analyzed using three techniques, i.e., centrifugal flotation in zinc sulfate solution, centrifugal flotation in sucrose solution, and methylene blue gram safranin staining. Eighty-nine of the samples were from stay dogs living in shelters run by animal protection societies, 199 were from kennels and 122 from households. A total of 119 (29.0%) had G. duodenalis cysts and six (1.4%) were positive for Cryptosporidium spp. oocysts. Dogs from kennels were most frequently affected by G. duodenalis (49.7%) while those from shelters showed a higher prevalence of Cryptosporidium spp. (2.2%). A significant difference (p < or = 0.05) was observed between immature dogs and adults only with respect to Giardia infection. There was no significant difference between the gender with regard to the presence of either protozoan.

One hundred fecal samples from male and female dogs of several ages and breeds were collected in kennels of Uberlândia in Minas Gerais, Brazil. These samples were analyzed to determine the frequency of Giardia spp. using two different diagnostic methods: zinc sulfate flotation technique and merthiolate-iodine-formaldehyde concentration (MIFC). The frequency of giardiasis was 41 percent. Dogs, which were less than 12 months of age, were the most parasitized (68.4 percent). No difference between male and female frequency of giardiasis (31.4 percent and 46.1 percent, respectively) was observed. MIFC detected 38 percent of positive samples and zinc sulfate flotation technique 29 percent. Giardia spp. is present in dogs of Uberlândia's kennels in a high frequency
