Bacteriological profile and antibiotic sensitivity pattern of blood culture isolates from tertiary care level teaching hospital of Vijayapura district

Raveendra D. Totad, Praveen Ganganahalli

Abstract


Background: Blood stream infections, ranging from self-limiting bacteraemia to life threatening septicaemia, remain one of the most important cause of morbidity and mortality worldwide. Sepsis is a systemic illness caused by microbial invasion of normally sterile parts of the body. Bacteria isolated from blood stream infections are numerous and diseases related to them need urgent treatment with antimicrobial drugs. Aim was to study the bacteriological profile of positive blood cultures and to find their antibiotic sensitivity pattern

Methods: A retrospective analysis of positive blood culture reports was done in the microbiology laboratory of present tertiary care teaching hospital (Al-Ameen Medical College, Vijayapura) for the consecutive year 2017, 2018 and 2019.

Results: Total 21% samples found positive on blood culture shows Staphylococcus aureus as most common organism followed by Klebseilla and E.Coli antibiotic sensitivity pattern shows maximum sensitive to gentamicin (92%) and vancomycin (92%) as maximum resistance to penicillin (55%). Gram-positive organisms show more resistance to penicillin and least to vancomycin whereas gram-negative organisms show more resistance to cephalosporin group of antibiotics and least resistance to ciprofloxacin/gentamicin.

Conclusions: Resistance pattern of organisms to some commonly used drugs has given warning signal to clinicians to search for alternate effective antibiotics and hospital authorities to formulate antibiotic policy for rationale use of antibiotics to prevent drug resistance.
