Gastrointestinal and respiratory parasites in captive mammals at Rabat zoo, with the first record of Capillaria spp. in the Fennec fox (Vulpes zerda).

The aim of the present study was to broaden the understanding of parasitism in captive wild mammals in Morocco. For this purpose, an investigation on gastrointestinal and respiratory parasites in African mammals from Rabat Zoo was carried out. A total of 47 fecal samples were collected from 30 species from November 2021 to March 2022 and examined macroscopically and microscopically. Parasites were detected in 21 species at a prevalence of 70%, with a parasite positivity rate of 89% in artiodactyls, 50% in perissodactyls, 67% in both carnivores and primates. No parasitic infection was detected in proboscideans. The most frequent infection was by nematodes with a percentage of 50%, followed by both protozoa and mixed infection with a prevalence of 10%. In conclusion, the results demonstrated that parasite prevalence remains high, even in enclosed spaces like zoos. Therefore, in order to ensure animal welfare and staff safety, sanitary measures should be implemented in such facilities, including routine diagnostic tests followed by appropriate treatment.
