Abstract
Bacterial infections are very common and diagnosis takes a minimum of three days. It is essential to treat patient empirically before report arrives as sometimes it may assert fatal consequences on the patient. 14891 clinical specimens of various infection sites were studied and cultured with the help of routine streak plate method or BacTec9050 machine, especially for blood and body fluids. If growth observed then identification was carried out using MicroScan autoScan4. 4990 specimens shown growth of either bacteria or Candida species. Stool culture shows highest positivity 84.2, followed by Pus 49.9%, Urine 46.3%, Tracheal aspirate 38.6%, Sputum 26.9%, Body fluids 9.2% and Blood shows lowest 4.8% positivity.64 different organisms were identified from this study. Gram-negative organisms dominated over Gram-positive and Candida species. E. coli was the most isolated organism with the share of 48.4% followed by K. pneumoniae (13.6%), P. aeruginosa (11.6%), A. baumannii (5.7%), S. aureus (5.0%) and C. albicans (2.0%). By assuming the causative agent before starting empirical treatment can act as lifesaving in critical situations. It also helps to choose the most suitable antibiotic from the pool instead of haphazard use.
