Background: Primary pyodermas are one of the most common dermatological diseases. Staphylococcus aureus (S. aureus) is frequently isolated. It has developed resistance to many antimicrobials and Methicillin Resistant Staphylococcus aureus (MRSA) is a major problem. The precipitous usage of topical antimicrobials especially Mupirocin and Fusidic acid has increased the development of multi-resistant strains of S. aureus and in India, few studies have shown susceptibility profile to these drugs. Aim: This study aimed at the clinical and bacteriological profile in primary pyoderma patients, prevalence of MRSA and the resistance pattern of S. aureus to Mupirocin and Fusidic acid. Materials and methods: Patients with primary pyodermas from community were recruited. Gram stain and culture sensitivity was done with swabs taken from the lesions. Antibiotic susceptibility for S. aureus was tested using VITEK- 2. Mupirocin and Fusidic acid susceptibility was determined by E-strip method. Observations: A total of 107 patients of primary pyodermas were included. Pyoderma were common in young age group (P = 0.001). Poor hygiene was the main predisposing factor. Furunculosis (45.8%) was the most common pyoderma followed by impetigo and folliculitis (16.8% each). Culture was positive in all except 3. S. aureus was isolated in 61.7% and polymicrobial flora in 13.1%. Prevalence of MRSA was 39.5% (P= 0.066). All strains of S. aureus demonstrated 100% susceptibility to Mupirocin and Fusidic acid. Conclusions: Furunculosis still has the highest incidence in adult population with a high prevalence of MRSA (39.5%). Despite extensive usage of Mupirocin and Fusidic acid, no resistance was found in this part of India.
