Prevalence of Acinetobacter Infection in Hospital Environment and their Antimicrobial Sensitivity Pattern in North-East Region of Bangladesh

Acinetobacter species are the most important nosocomial and opportunistic pathogens. In South-Asian countries including Bangladesh, prevalence of Acinetobacter infection in hospital environment and their resistance to antimicrobial agents is significantly high. In this study, the prevalence of Acinetobacter infection from various hospitals and its correlation with patient's age, sex, hospital units, and different season were evaluated. In addition, the sensitivity patterns of Acinetobacter to different 23 antimicrobial agents were also assessed .Comparatively higher infection rate by Acinetobacter species was found in patients with lung infection, urinary tract infection and abscess. Interestingly, significantly higher infection by Acinetobacter was also seen at rainy season in intensive care unit (ICU), and medicine unit. Remarkably, antibiotic colistin was found with highest susceptibility (96.4%) followed by tigecyline (89.6%), iImipenem (57.7%) and meropenem (51.4%). Rest of the 19 antibiotics showed less than 50% susceptibility. Therefore, this hospital based study on Acinetobacter infection suggesting to implement a strict antibiotic management policy of its spread among the patients
