Being a new institute, antibiotic policy is still not in place. We have made an effort to set the empiric treatment for Gram positive cocci and Gram negative bacilli causing aerobic pyogenic infections. Material and Methods: The total of 134 pus samples received at the bacteriological section were inoculated onto Blood agar and MacConkey agar media and incubated at 37°C for 24 hours and identification of bacteria from positive cultures was done with standard microbiological technique. The antimicrobial susceptibility tests (AST) were done by Kirby–Bauer’s disk diffusion method on Mueller–Hinton agar and interpreted as per Clinical Laboratory Standard Institution guidelines. Observation and Result: The most common organism was Staphylococcus aureus 53.84%, followed by Escherichia coli 20.87% and Pseudomonas species 5.49%. Conclusion: This study concludes by proposing Gentamycin and Ceftriaxone as empirical treatment for Gram positive cocci and Gram negative bacilli.
