Abstract

A total of forty two resident animals representing eighteen wildlife species at the Federal University of Agriculture (FUNAAB) Zoo Park were screened for nematode helminths between May and June 2013. Freshly voided faeces from the animals were subjected to basic coprology tests (Direct Microscopic Examination and Concentration Techniques). Trichuris specie. was the most prevalent nematode in primate species. Prevalence of 14.3% and 28.6% were recorded for Capillaria specie and Strongyles in the primates respectively. A prevalence of 100% infection with nematodes in screened fourteen (14) primates was recorded. Mona and Vervet monkeys have the highest points for parasite richness count of 2 out of 3 detected nematodes amongst the primates. Wild birds at the park recorded the lowest prevalence for any type of nematodes with 7 out of 8 species without any nematode detected. Ascaridae was only detected in carnivorous reptiles and birds. In terms of feeding category, carnivorous species namely the (Aquila spilogaster) and Royal python (P. regius) have the highest species richness count of parasites. Non-nematode helminths detected include protozoons (Isospora and Eimeria) and Cestodes segments suspected to be Echinococcus proglotids. Knowledge of the helminth parasites in wild animals is vital in formulating preventative veterinary protocols in captive exhibits. This is the first documented account of nematode helminths of resident wild animals at the FUNAAB Zoo Park, Abeokuta.
