Clinicobacteriological study of pyoderma with special reference to community acquired methicillin resistant staphylococcus aureus.

ABSTRACT

Background: Although prevalence of MRSA strains is reported to be increasing, there are scanty studies of their prevalence in community acquired pyoderma in western India. Aims: This study aimed at determining clinicobacteriological profile & prevalence of Methicillin Resistant Staphylococcus aureus (MRSA) infections in community acquired pyoderma. Materials and methods: Prospective study was carried out in tertiary care hospital in Baroda.100 patients with pyoderma, visiting outpatient department of dermatology, were studied clinically and microbiologically. Sensitivity testing was done for gram positive & gram negative organisms by disc diffusion method. MRSA were detected by Agar dilution method. Result: Primary pyoderma accounts for 64% of cases with highest number of cases were of Impetigo (26%). The culture positive rate was 83% with Staphylococcus aureus being the major pathogen. (78.82%) Out of these 10.45% strains of Staphylococcus aureus were Methicillin Resistant Staphylococcus aureus. (MRSA) Conclusion: MRSA as a cause of pyoderma is a reality albeit in present study group. All the MRSA isolated were sensitive to Vancomycin. Sensitivity to Amoxyclav, Fluoroquinolones & Macrolides is quite good, which can be used for treatment.
