Acinetobacter spp. in the patients and environment of University Hospital of Yopougon, Cte dIvoire, from 2007 to 2011

The objective of this work was to study the epidemiology and antibiotic resistance of strains of Acinetobacter spp. in the University Hospital of Yopougon Abidjan. This work studied the Acinetobacter strains isolated from humans and environment of the hospital; they were preserved in the culture collection of the Laboratory of Bacteriology from January 2007 to December 2011. Isolation and identification were made by conventional bacteriological methods, and antibiotic susceptibility was studied by the method of agar diffusion. Interpretation was made according to the standards of the CA-SFM. 110 strains of Acinetobacter spp. have been studied (61% of human strains and 39% of strains isolated from the hospital environment). Acinetobacter baumannii was the most isolated in 66% of cases. 52. 8% of strains were resistant to ceftazidime; 5.6% to imipenem; 21.2% to gentamicin and 35.2% to ciprofloxacin. 12.5% of human strains of A. baumannii were multi-resistant bacteria. Acinetobacters spp. are present in the hospital environment and patients with a predominance of A. baumannii species. The presence of imipenem-resistant strains is a major public health problem because their disclosure could lead to therapeutic impasse in hospital. Key words: Acinetobacter spp., epidemiology, antibiotic resistance.
