Bloodstream infections and antimicrobial sensitivity patterns in a tertiary care hospital of India.
BACKGROUND
Invasion of the bloodstream by microorganisms constitutes one of the most serious situations in infectious disease. Microorganisms present in circulating blood whether continuously, intermittently, or transiently are a threat to every organ in the body. Prevalence and antimicrobial susceptibility of microorganisms vary depending upon the geography and the use of antibiotics.


METHODS
A cross-sectional study to determine the prevalent organisms causing bloodstream infection was conducted. BACTEC BD 9050 system was used to identify the causative organism, and sub-cultures were done on MacConkey Agar and Blood Agar. Antibiotic susceptibility test (AST) was done using Kirby B Disk diffusion method.


RESULTS
A total of 170 patients were enrolled, and blood samples of 53 patients showed growth of organisms.Staphylococcus aureuswas the most commonly isolated organism. Most of the Gram-positive cocci (GPC) were susceptible to vancomycin and linezolid. Most of the Gram-negative bacilli (GNB) showed sensitivity to cefoperazone/sulbactam followed by imipenem.
