Abstract

Objective Carriage of Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA) is a problem within healthcare organizationsand in the community. The aim of the study was to screen S. aureus carriage and their susceptibility to cefoxitin and oxacillin amongmedical students.Methods A total of 100 nasal swabs were collected. Isolation and identification of the isolate as S. aureus was done using Gram stain,coagulase test and catalase test. S. aureus isolates were confirmed as MRSA using cefoxitin (30 μg) disc and oxacillin (30 μg) disc by Kirby-Bauer disc diffusion method on Mueller-Hinton agar. From 100 nasal swabs, 76 were coagulase negative Staphylococci and 20 werecoagulase positive Staphylococci.Results From 100 nasal swabs, 76 were coagulase negative Staphylococci and 20 were coagulase positive Staphylococci. From these, 60%and 40% were oxacillin- and cefoxitin-resistant isolates, respectively. The data obtained from this study revealed that there were carriers ofMRSA among the medical students.
