Detection of Antimicrobial Susceptibility Pattern of Staphylococcus aureus among Clinical Samples Received in Department of Microbiology in Integral Institute of Medical Sciences and Research, Lucknow, Uttar Pradesh: A Retrospective Analysis

Background: Staphylococcus aureus is the most significant species of staphylococci which has been recognized as an important cause of human disease for more than 100 years. It produces infections which range from localized pyogenic infections to life threatening systemic infections in man. Material & Methods: A retrospective study was done over a period of 12 months from April 2018- March 2019 in the Department of Microbiology at Integral Institute of Medical Sciences and Research, Hospital, Lucknow, India. The study was approved by the Ethical Research Committee (ERC) of the Institute. Data entry and statistical analysis were performed using the Microsoft Excel. Result: Total samples were 3, 322 out of which 306 (9.2%) were positive culture of staphylococcus aureus. In this study, females 164 (53.6%) were more affected than male 142 (46.4%). Maximum number of patients belong to age group 0-9 (27.8%) followed by 30-39 age group (19.9%). Conclusions: Out of 306 positive staphylococcus aureus, 33 were MRSA which was followed by 25 of CoNS. The Antimicrobial susceptibility pattern shows that s. aureus was susceptible to Vancomycin (VA), Teicoplanin (TEI) & linezolid (LZ) (100%) followed by Tobramycin (TOB) 98.8% andAmikacin (AK, 97.6%).
