Objective: To check the Bacterial Co-infections and Susceptibility patterns among admitted COVID-19 patients during 3rd wave of pandemic. Study Design: Descriptive Cross Sectional study. Setting: Department of Microbiology, Combined Military Hospital Lahore Pakistan. Period: May 2021 to August 2021. Material & Methods: Six hundred and twelve COVID-19 positive patients having positive bacterial cultures were processed, Antibiotic susceptibility testing was done by Kirby-Bauer diffusion technique, all antibiotics were reported using breakpoints recommended in clinical and laboratory standards institute (CLSI 2021). Results: Out of 612 patients, 348 (56.9%) were male and 264 (43.2%) were female. Mean age of the patients was 57.2 ± 14.4 years with a range of 22 to 89 years. Bacterial coinfection was present in 70.4% of the patients. Gram negative bacteria (94.4%) were more prevalent in COVID-19 patients as compared to gram positive isolates (5.6%). Antibiotic sensitivity pattern of Staphylococcus aureus showed a high resistance against penicillin, ampicillin, tetracycline and doxycycline. Conclusion: Our study reported a high prevalence of bacterial coinfections in COVID-19 patients infected during the third wave of pandemic. A high percentage of gram negative species were identified in our study population, this could be due to the suppression in the immunity of individuals due to severity of COVID-19 infection and already present Antimicrobial resistance.
