Giardia infection in animals in Poznań Zoo

One hundred and eighty-four faecal samples from 170 animals of 82 different species in Poznań Zoo were examined with direct wet mounts in physiological saline and permanent smears stained with iron-haematoxylin. Giardia spp. cysts were found in one chimpanzee, four marmosets, two North American porcupines, a European wild cat and a serval. The infection in the porcupines was very intense and resistant to metronidazole treatment.
