Antibiogram of klebsiella pneumoniae recovered from blood stream infection at tertiary care hospital, Baroda, Gujarat
Introduction: Antimicrobial abuse is a serious risk factor for the emergence of multi-drug-resistant (MDR) pathogens. Multidrug resistant (MDR) Klebsiella pneumoniae is an increasing cause of blood stream infections in India and in other developing countries.
Aim: This study was undertaken to determine the prevalence of Klebsiella pneumoniae in blood stream infections and their susceptibility pattern at S. S. G. Hospital, Baroda.
Material and Methods: 169 isolates of Klebsiella pneumoniae were obtained from blood culture samples from hospitalized patients. K.pneumoniae species were identified based on biochemical reactions. Their sensitivity pattern were checked by Kirby-bauer disc diffusion technique as per CLSI guideline. Antimicrobial discs used were Ceftazidime (30µg), Cefotaxime (30µg), Imipenem (10 µg), Levofloxacin (5 µg), Aztreonam (30 µg), Co-trimoxzole (25 µg), Ampicilin (10 µg), Gentamicin (10 µg), Amikacin (30 µg), Doxycycline (30 µg).
Results: 950 blood cultures were studied from suspected patients and the prevalence of K. pneumoniae among them was checked with its antimicrobial susceptibility at Department of Microbiology, Tertiary care hospital, Gujarat. Among 950 suspected patients in the study period, K.pneumoniae was found in 169 blood culture samples.
Conclusion: Infections with K.pneumoniae are increasing, particularly among paediatric patients. This pathogen is usually multidrug-resistant and there are limited treatment options available. This result warns us for implementation of infection control measures to limit intra-institutional spread of these organisms.
