Bacterial Profiles Associated With Captive Non-Human Primates in Jos Zoo, Nigeria

Abstract

Non-human primates (NHPs) are distributed worldwide and have several unique features that may account for opportunistic and pathogenic zoonotic bacteria. Aim: To evaluate the incidence of enteric organisms with zoonotic and biohazard potential in captive NHPs in a zoo setting. Study Design: Descriptive study. Place and Duration of Study: This study was conducted in Jos, Plateau State, Nigeria between June-September, 2012. Methodology: We examined 33 clinically healthy young adult monkeys and apes over a three months interval. The animals were sampled at six weeks intervals by faecal culture. Samples were inoculated on appropriate media using specific selective culture methods. Suspect isolates potentially transmissible to humans were purified and identified based on their cultural and biochemical characteristics. Results: The survey revealed six (6) bacterial pathogens using API 20E, Escherichia coli (100.0%), Salmonella paratyphi A 31(93.9%), Proteus mirabilis 14(42.4%), Campylobacter species 6(18.2%), Citrobacter ferundii 7(21.2%), and Yersinia enterocolitica 3(9.1%). Conclusion: The incidence of infections during the period of study (first week and the twelfth week) indicated increased patterns of transmission between species of primates. Research among primate populations has the potential to predict which pathogens might enter human populations as human contact with these animals both in captivity and in the wild is on the increase.
