Introduction: Pyoderma is one of the common skin condition seen in dermatological OPD. Pyoderma are purulent infections of skin and its appendages mainly caused by various bacteria. Pyoderma could be primary or secondary to other conditions such as impetigo, carbuncle, folliculitis & others.
Materials and Methods: Two sterile swabs collected from the lesions each for Gram staining and culture. Culture done on sheep blood agar and MacConkey agar & incubated at 37C. Identification done by colony morphology, repeat gram staining & biochemical tests. Antibiotic sensitivity testing of Isolates done by Kirby bauer disc diffusion testing following CLSI guidelines.
Discussion: Of 315 cases diagnosed clinically as Pyoderma only 295 were culture positive. 59% of cases were primary type and impetigo was the most common type. Males were affected more than females in ratio 1.56:1. was found to be the most common cause of Pyoderma followed by and streptococcus pyogenes in gram positive bacteria. In gram negative bacteria is most common followed by The major associated risk factors for causation of Pyoderma were found to be Malnutrition (35%) followed by Diabetes (16.5%), Hypertension (6.3%) & multiple comorbidities found in 12.6% of cases. However in 94 cases (30%) no associated factors detected.
Conclusion: Pyoderma mainly affects males than females with 10-30yrs being the most common age group affected. is the most common causative agent. Antibiotic sensitivity testing is mandatory to treat effectively & control drug resistance.
