RESUMO
Parasitologic evaluations of 112 fecal specimens from 292 mammals from the Santiago National Zoo (36 specimens were pooled specimens from greater than or equal to 2 animals) indicated that 51 mammals had protozoa or helminths in their feces. Most of the parasites in the herbivorous species were trichurids and strongylids, whereas most of the parasites in the carnivorous species were ascarids. Coccidia spp and Giardia spp were the most frequently detected protozoans in the mammals evaluated. Of 127 captive mammals serologically evaluated for antibodies against Toxoplasma gondii (indirect hemagglutination test), 35 (27.5%) were positive for T gondii: 7 (46.6%) of 15 carnivores, 24 (25.2%) of 95 artyodactyls, and 4 (22.5%) of 17 nonhuman primates. Antibodies against T gondii also were found in 8 of 10 domestic cats captured within the zoo and in 6 of 13 volunteer zookeepers.
