Bacteriological profile of pus infection and antibiotic susceptibility pattern – a population study of east godavari district, coastal Andhra Pradesh

Pus infections are one of the most common Nosocomial infections accounting for 38% of all infections in post surgical patients. Its antibiotic susceptibility pattern under sterile aseptic precautions, pus exudate was collected using 2 sterile cotton swabs for aerobic culture. It was inoculated onto blood and MacConkey agar and Nutrient agar media. The samples were processed as follows, direct microscopic examination of gram stained smear, preliminary identification by colony morphology, biochemical test for characterisation of species and antibiotic sensitivity testing. Out of 75 cases, 44 were male patients and 31 female patients with infection rate more in males. Culture positive were 52 and culture negative were 23. In the culture positive, all are aerobic . Among the aerobic isolate Staphylococcus, was the most common gram positive organism isolated and Pseudomonas aeruginosa was the most common gram negative organism isolated. Intervention aimed at reducing pus infection would provide cost savings and improve the efficiency of health care system.
