Prevalence of aerobic bacterial pathogens in sepsis cases at a tertiary hospital, Bangladesh

Abstract

Background: sepsis remains an important cause of morbidity and mortality in hospitals especially in developing countries like Bangladesh. It is one of the top 10 leading causes of death worldwide pose and great challenge in critical care. Still, it is a major health problem and creates a biggest challenge for the clinicians. Objectives: To isolate and identify aerobic bacteria in sepsis cases admitted in Rajshahi Medical College Hospital. Methods: A descriptive type of cross-sectional study was carried out in the Department of Microbiology, Medicine, Surgery and Obstetric & Gynae Dept. of Rajshahi Medical College and Hospital during January 2015 to December 2015 A total of 60 blood samples were collected from clinically diagnosed cases of sepsis and cultured on conventional method using brain heart infusion broth. Results: Culture had yielded growth of bacteria was 23(38.3%) cases, off which E. coli was 7(30.5%), Staphylococcus aureus was 6(26.1%), Staphylococcus epidermidis was 4(17.4%), Acinetobacter spp. was 3(13%), Klebsiella pneumoniae was 2(8.7%), pseudomonas aeruginosa was 1(4.3%). Out of 23(38.3%) culture positive cases 12(52.2%) were male and 11(47.8%) were female persons. Conclusion: A good number of patients of both sexes were suffering from sepsis and common aerobic bacteria were responsible for it. Another good number of cases may suffer from anaerobic bacteria which are not included in this study.
