Acinetobacter septicemia in neonates admitted to intensive care units

Abstract

Background: Acinetobacter species are gaining importance as potential pathogens in neonatal septicemia because of their frequent isolation and multidrug resistance. Aims and Objectives: The aim of the present study was to evaluate the role of Acinetobacter spp. as important pathogens in neonatal blood stream infection, to identify the associated risk factors, and to evaluate the drug sensitivity pattern. Materials and Methods: Blood samples of infected neonates were studied bacteriologically. Cases of Acinetobacter septicemia were identified. Speciation of Acinetobacter species was done. Various risk factors were identified. The drug-sensitivity test was done. Results: A total of 26 Acinetobacter septicemia cases were identified by blood culture. Acb complex strains predominated. Institutional birth and preterm birth were identified as the most frequent significant risk factors. 11.3% mortality rate was recorded. Acb complex strains exhibited a multi-drug resistant pattern. No carbapenem resistance was observed. Conclusion: Acinetobacter should be added to the list of organisms causing severe nosocomial infection in neonatal intensive care units. Continuous bacteriological surveillance, implementation of infection control policies, careful disinfection of intensive care equipment, and rational antibiotic use are required for control of such infections.
