Introduction: Microorganisms present in circulating blood are a threat to the every organ of the body. Blood stream infections can have serious consequences and timely detection and identification of blood stream pathogen is one of the most important functions of microbiology laboratory. Positive blood culture helps in providing a specific etiological diagnosis and antimicrobial susceptibility pattern.
The present study was undertaken to find the pattern of etiological agents of BSI & their antimicrobial susceptibility.
Materials and Methods: A study was carried out from July 2016 to December 2017 at a tertiary care hospital, Udaipur, Rajasthan, India using conventional blood culture method. Organisms were identified by standard microbiological procedures and antibiotic sensitivity was performed using the kirby-bauer disk diffusion method.
Result and Discussion: A total of 800 samples of suspected blood stream infections (BSI) were included during the study period. Bacterial growth was obtained in 299 samples (37.37%). Gram-positive cocci accounted for 53.16% and Gram negative for 46.50% and candida species as 0.33% of positive cultures. Coagulase negative staphylococcus (38.12%), Staphylococcus aureus (13.04%), Pseudomonas species (13.71%) and Klebsiella species were predominant organisms. The antimicrobial susceptibility pattern of blood isolates showed high resistance to routinely used antimicrobial agents.
Conclusion: This emphasizes the importance of institutional antibiotic policy, stringent infection control practices and judicious use of antibiotics.
