Abstract :
Introduction: Cutaneous bacterial infections may be divided into primary and secondary types. The majority of primary and secondary
pyodermas (cutaneous bacterial infections) are caused by either Staphylococcus aureus or group A Streptococcus. Changing trends are being noted
in the etiological aspect of primary pyodermas and the problem of emergence of drug resistant strains is an ever increasing one. Antibiotic
resistance has become a clinically important consideration in many infections, but methicillin resistant S. auerus (MRSA) which has been a
nosocomial problem for years, is now a common community acquired skin infection.
MATERIALS AND METHODS:
Study Design: Descriptive study. Duration of study: 1 year
Inclusion criteria: Clinically diagnosed cases of primary pyoderma of both sex and age between 1 to 12 years.
Exclusion criteria: Patients with primary pyoderma started on antibiotic therapy.
Sample collection: Smears made from the pus were stained with gram‘s stain. Pus was cultured on blood agar and Mackonkey‘s agar and incubated
aerobically at 370 C for 48 hours. Sensitivity of the organisms to antibiotics was tested on Mueller Hinton agar. Antibiotic sensitivity was tested by
disc diffusion technique using Kirby Bauer method.
Observation: Gram staining of the pus demonstrated organisms in 78% cases. Most common organism in gram staining was gram positive cocci.
Culture positivity in this study was 84%. The most common organism isolated in the present study was Staphylococcus aureus accounting for
80.95%, with low percentage of Streptococcus pyogenes (2.38%) and Escherichia coli (2.38%) but with a higher percentage of mixed organisms
(14.29%). The observation of methicillin resistant Staphylococcus aureus was observed in 9.52% of cases. Staphylococcus aureus showed
sensitivity to cloxacillin (100%) followed by first generation cephalosporin (94.11%) and amikacin (73.53%). Streptococcus pyogenes showed
sensitivity to penicillin and gentamicin in all the cases. MRSA was sensitive to amikacin, vancomycin and linezolid in all the cases.
Conclusion : The most common organism isolated in culture was Staphylococcus aureus. MRSA was isolated from 9.52% cases. Staphylococcus
aureus showed sensitivity to cloxacillin (100%) followed by first generation cephalosporin (94.11%) and amikacin (73.53%). MRSA was sensitive
to amikacin, vancomycin and linezolid in all the cases.
