Abstract
Health-care workers are presumably important in MRSA transmission, although, they more frequently act as vectors than the main sources of MRSA transmission. Asymptomatic methicillin-resistant Staphylococcus aureus (MRSA) carriage among Health care workers (HCWs) in the University of Port Harcourt Teaching Hospital, Nigeria was investigated. Hand and nasal swabs were collected from two hundred and twenty-two HCWs (111 males and 111 females). Following standard microbiological protocols, samples were processed for isolation of Staphylococcus aureus while detection of MRSA was done using the Disk diffusion method-performed with oxacillin(1μg) disk placed on Mueller-Hinton agar with 4% NaCl supplementation. Of the two hundred and twenty-two HCWs (111 males and 111 females) involved, Staphylococcus aureus were isolated in 78 subjects (35.1%) whereas 5 (2.3%) of the total subjects yielded MRSA. As regards gender, out of the 5 isolates of MRSA, females HCWs showed higher but non-significant carriage rate (6.67 %) of the methicillin-resistant Staphylococcus aureus than in their male counterparts (6.06 %). This study involved age groups 20 to 30, 31 to 40 and 41 to 50 which gave MRSA incidence rates of 2 (6.25%), 2 (8.0%) and 1 (4.76%) respectively suggesting there is no significant relationship between MRSA carriage and the age groups of the study population. Among the antibiotics used for susceptibility testing, vancomycin showed the highest susceptibility rate of 94 %, followed by ciprofloxacin (59 %) and the least being cloxacillin (21 %). Regular screening of HCWs and high hygiene standards are instructive in the prevention and control of MRSA transmission and for a robust infection control programme
