The Human-Animal Health Barrier: The Role of Livestock-Associated Methicillin-Resistant Staphylococcus Aureus (MRSA) Under Pastoralist and Sedentary Farming Systems In Kenya

The project is using One Health approach in investigating the emergence and spread of Methicillin Associated Staphylococcus aureus (MRSA) and other antibiotic resistant bacteria at the human-animal interface in Kajiado and Kiambu Counties in Kenya. The study is a continuation of Kagira's work on surveillance of antimicrobial resistance (AMR) in livestock in Kenya. Preliminary work by Kagira and a team of researchers have shown high prevalence of AMR in bacteria isolated from ruminants having mastitis. Consumption of milk/milk products contaminated with resistant bacteria as well as close interaction between livestock and people is a critical entry point of these microorganisms into the food chain. Indeed, recent studies in Kenya have shown high prevalence (>84%) of MRSA at human hospital settings leading to increased morbidity, mortality, and financial constraints. The current project is geared towards using modern molecular tests such as genetic typing to provide the much needed evidence that livestock associated-MRSA and other resistant bacteria are able to breach the livestock-human barrier and cause severe disease in man. Results of the project will be used in informing One Health policies on surveillance and management of AMR where veterinary and medical authorities work together in managing the menace.
