First Report of Biofilm-forming, Multidrug-resistant Coagulase-negative Staphylococci from Butcher Tables in Enugu, Nigeria: A Public Health Awareness

Benjamin Onyebuchi Osuji, Chidinma Stacy Iroha, Ismaila Danjuma Mohammed, Ikechukwu Jude Ebenyi, Oforbuike Okeh, Ikemesit Udeme Peter & Ifeanyichukwu Romanus Iroha · International Journal of Pathogen Research · 2026

Background: Coagulase-negative Staphylococci (CoNS) have evolved from commensals to significant opportunistic pathogens, primarily due to their capacity for biofilm formation and the acquisition of multidrug resistance (MDR) genes. In low-resource settings, meat processing surfac...
