Background: S. aureus, coagulase negative staphylococci, enterococci, a variety of gram-negative bacilli, and Candida spp. are responsible for the vast majority of infections. Coagulase negative staphylococcal infections have increased dramatically in past 2 decades, almost entirely because of increase in the frequency of blood stream infections caused by these organisms.
Methods: Appropriate microbiological samples were taken from the site of infection from all the patients included in the study. Whenever necessary, required serological examinations are sent.
Results: Of 30 episodes of nosocomial infections from which any pathogen was isolated, three episodes were polymicrobial. Gram-negative organisms were more frequently (76.67%) isolated than gram-positive organisms (20%), and fungi (3.33%).
Conclusions: Almost all gram-negative bacteria showed 100% sensitivity to Imipenem. Pseudomonas isolates showed sensitivity of 100% to Imipenem, 83.33% to Piperacillin+Tazobactum. Klebsiella showed sensitivity of 83.33% to Ciprofloxacin and Amikacin.
