Prevalence of Methicillin Resistance Staphylococcus aureus in Community Cases of Pyoderma

Aim: To determine the susceptibility pattern of Methicillin-Resistant Staphylococcus aureus (MRSA) isolates pyoderma cases. Study design: Cross-sectional. Place and duration: Research was conducted in department Microbiology collaboration with Department Dermatology, Jinnah Postgraduate Medical Centre, Karachi, during period 1.8.2022 to 25.11.2022.

Isolates identified by routine assay antimicrobial determined disc diffusion method. Results: Out 232 specimens, 196 (84.5%) culture positive; 170(86.7%) Gram-positive, 25(12.7%) Gram-negative 1(0.6%) Candida sp. S.aureus prevalent offender (119; 51.2%), followed S.pyogenes (51; 22%) S.epidermidis (3; 1.3%). showed 73(61.3%) MRSA. The highest rate resistance among all S. recorded for, penicillin, cefoxitin ciprofloxacin, 89; 74.7% 73; 61.3% 72; 60.5% respectively. Conclusion: is a significant number Therefore it mandatory for dermatologist start treatment after sensitivity testing failure recurrences. Keywords: aureus, Pyoderma, aureus,Streptococcus pyogenes.
