Abstract

Non-diphtheritic Corynebacteria (NDC), originally considered contaminants in clinical samples, have now emerged as nosocomial pathogens, emphasising the importance of their identification and prompt reporting. 120 non-diphtheritic corynebacteria isolated from pus were chosen for examination. A battery of tests identified isolates and minimum inhibitory concentration (MIC) was detected by broth micro-dilution and interpreted as per Clinical & Laboratory Standards Institute (CLSI) and British Society for Antimicrobial Chemotherapy (BSAC) guidelines. C. amycolatum 28 (31%), followed by C. striatum 18 (20.5%) was the predominant isolate. Cephalosporins were least effective followed by Gentamycin. However, all isolates were sensitive to Vancomycin and Linezolid. Our research highlights the necessity of implementing clinical antimicrobial therapy protocols for Corynebacterium spp. Empirical treatment with vancomycin or linezolid is recommended until in vitro susceptibility results become accessible.
