Abstract :
Background: Staphylococcus aureus is a common health problem occuring as an important nosocomial pathogen, causing urinary tract infection, surgical site, blood stream and soft tissue infection. The aim of this research was conducted to determine MRSA and VRSA from the pus samples of admitted patients.
Aim & Objective: The aim and objective of study was to isolate the resistance pattern of Staphylococcus aureus in pus samples and their AST.
Materials and Methods: A total of 158 positive culture Staph aureus were taken from pus samples for the study during December 2019 - October 2020. Samples were cultured on Blood and MacConkey agar then incubated at 37C for 24 hours. The modified Kirby Bauer's disc diffusion method was used to test antibiotic sensitivity of staphylococcus isolates.
Result: In total of 158 positive culture of Staphylococcus aureus, 66 (41.7%) were found to be MRSA and 4 (2.5%) were found to be VRSA. Out of 158 Staph aureus, 146 (92.4%) were resistant to Penicillin, followed by Amoxycillin 140 (88.6%), Ampicillin 139 (87.9%), Erythromycin 91 (57.5%), Cefoxitin 66 (41.7%), Gentamycin 56 (35.4%), Amikacin 52 (32.9%) and Teicoplanin 37 (23.4%).
Conclusion : An antibiotic policy and screening of susceptibility patterns of MRSA may help in reducing the prevalence rate of MRSA and antibiotic resistance. To stop its spread to the population, it is very important to eliminate MRSA colonization in patients and health care workers. Accurate treatment helps to reduce the rate of morbidity and improvement of patient’s outcome.
