Cellulitis is a microbial infection involving the skin. It usually involves the dermis and connective tissue fat, presenting with expanding erythema, warmth, tenderness and swelling. To study the Bacteriological profile of Cellulitis patients, and their antibiogram. A total of 100 Patients having skin infections with Cellulitis were included in the present study . Pus samples were collected with a sterile swab after cleaning the adjoining area following standard procedures. They were processed by Gram’s staining and was inoculated on to MacConkeys agar and Blood agar. Isolates were identified according to standard bacteriological techniques. Antibiotic susceptibility testing done by using Kirby Bauer disc diffusion technique on Muller Hiltons agar. Male Patients had higher susceptibility to skin infections associated with Cellulitis. Among the total collected 100 samples, pathogenic organism were isolated from 91 samples while  only commensals  grown in 9 samples. Most common organism isolated was Pseudomonas species 25 (27%), followed by Klebsiella 17 (18%), Escherichia coli 15 (16 %), Citrobacter species 15(16%]) Proteus species 11(12%), Staphylococcus  aureus 5 (5.4 %) and Acinetobacter species 2(2.1 %). Most of the Gram negative bacilli were sensitive to meropenem (90%), aminoglycosides (40%)  and cephalosporins (10%). Gram positive cocci were sensitive to aminoglycosides(60%) and cephalosporins (50%). Cellulitis is one of the important affliction of skin involving multidrug resistant microbes.  In our study most common organism isolated was Pseudomonas species, Mostly sensitive to carbapenems ,  and resistant to most of the other drugs.
