Abstract

This study was carried out in order to determine the prevalence of Staphylococcus aureus on door handles and the antibiotic susceptibility of the organism to some commonly used antibiotics in Nasarawa State University, Keffi, Nigeria. A total of 100 door samples were obtained, 20 each from the five faculties within the university’s main campus. These were cultured and identified using appropriate protocols. A total of 26(26.0%) isolates were identified as Staphylococcus aureus. Faculties of Administration and Arts jointly accounted for the highest prevalence with 40%. The antibiotics susceptibility test revealed that Gentamicin was the most effective of all the test antibiotics against the Staphylococcus aureus isolated. The multidrug resistant S. aureus isolates 12(46.2%) were observed to have produced beta lactamase enzymes implicated in beta lactam antibiotics resistance. Observation from this study showed that there is a high level of antibiotics abuse or misuse with resultant multidrug-resistant S. aureus isolates in the study area.
