Antibiotic Susceptibility Patterns of Staphylococcus Aureus and Coagulase-Negative Staphylococci in Dental Professionals

Abstract

Introduction: The occurrence of multidrug-resistant S.aureus strains is a substantial problem in healthcare sector across the globe. The World Health Organization (WHO) highlights the widespread prevalence of MRSA, resistant to multiple antibiotics, across various healthcare settings globally. According to WHO and CDC to over 100,000 deaths in 2019. The objective of this study was to determine the frequency of methicillin-resistant S. aureus (MRSA) and methicillin-resistant Coagulase-negative Staphylococci (MRCoNS) among dental students and healthcare workers, as well as their patterns of drug resistance.

Materials and Methods: The present study involved 36 healthcare workers from Sree Balaji Dental College & Hospital, located in Chennai, India. Nasal swabs were collected from the participants for microbiological examination. identification and antimicrobial susceptibility testing done by the standard procedures.

Results: Out of all the patients, 25% were found to have S. aureus contaminants with a prevalence of MRSA at 22.2%. Inaddition36.1% of the participants were identified with CoNS, including 19.4% with MRCoNS. Compared to Male workers a higher incidence observed among females. The analysis of antibiotic resistance profiles observed different susceptibility patterns among the isolates, following Resistant was observed significantly against cefoxitin, gentamicin, and erythromycin.

Conclusion: This study emphasises the significance of monitoring and implementing steps to reduce the spread of antibiotic-resistant staphylococcal infections in healthcare facilities
