Epidemiology and Antibiotic Resistance of Gram Positive Cocci Isolated from Infected Swabs and Blood Specimens

BACITRACIN, INTERMEDIATE, WOUND SWAB, STAPH AUREUSAbstract
Resistance to antimicrobial drugs is a significant health problem affecting the world. Bacitracin A is an efficient growth inhibitor for many Gram-positive bacterial species, but it has little impact on Gram-negative microorganisms. This study aimed to estimate the antibacterial activity of bacitracin against Gram-negative bacterial infections which isolated from clinical specimens. A cross-sectional quantitative study involving bacteriological analysis was conducted at Al Saleem medical laboratory from January 2021 and August 2022. In general, blood, fluid and swabs specimens are collected from the wounds suspected to be infected and were sent for culture to the Microbiology Department. A total of 51 (68.9%) Staph aureus isolates was obtained from wound swabs, followed by 5 (6.7%) Strep pneumonia. Gender does not appear to have any effect on the presence and prevalence of the different identified gener.. In the present study, Somewhat, Gram-positive bacteria were intermediately susceptible to bacitracin antibiotic. In staph aureus isolates, 10.8% were resistant to the Bacitracin antibiotic. 9.4% of Strep pneumonia showed intermediate susceptibility to it. Bacitracin is a broad-spectrum antibiotic that can be used to prepare a variety of therapeutic formulations such as infections, wounds and microbiological infections.
