- W2912160260 abstract "Metallo-beta-lactamase-producing Acinetobacter spp. is a major challenge for therapeutic treatment of nosocomial infections. This study is aimed at determining the prevalence of MBL-producing Acinetobacter spp. among 87 clinical isolates of Acinetobacter spp. from the Korle-Bu Teaching Hospital, Accra, between August 2014 and July 2015. Acinetobacter spp. was identified by standard bacteriological method, and resistance to different antibiotics was assessed with the Kirby–Bauer disc diffusion method. Meropenem-resistant Acinetobacter isolates were screened for enzyme activity using the modified Hodge test (MHT) and combined disc test (CDT). Additionally, multiplex PCR was used to determine MBL genes presence ( bla VIM , bla IMP, and bla NDM). All Acinetobacter isolates showed high resistance to cefotaxime (90.8%), ceftazidime (75.9%), cotrimoxazole (70.1%), ciprofloxacin (64.4%), gentamicin (72.4%), levofloxacin (67.8%), and meropenem (59.8%). A total of 54 (62.1%) of Acinetobacter isolates were multidrug-resistant. Out of 52 (59.8%) meropenem-resistant Acinetobacter , 3 (5.8%) were carbapenemase producers by MHT, whilst, 23 (44.2%) were CDT positive. There was no significant difference between the resistance pattern of amikacin, ceftazidime, cotrimoxazole, ciprofloxacin, and meropenem amongst CDT-positive and CDT-negative isolates (<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=M1><mml:mi>p</mml:mi><mml:mo>></mml:mo><mml:mn>0.05</mml:mn></mml:math>). A total of 7/87 (8.1%) CDT-positive Acinetobacter isolates harboured bla NDM; of these, 4 (57.1%) were from wound swabs, urine (<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=M2><mml:mi>n</mml:mi><mml:mo>=</mml:mo><mml:mn>2</mml:mn></mml:math>) (28.6%), and ear swab (<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=M3><mml:mi>n</mml:mi><mml:mo>=</mml:mo><mml:mn>1</mml:mn></mml:math>) (14.3%). The study revealed that less than 9% of Acinetobacter spp. contained bla NDM encoding genes. Strict antibiotics usage plan and infection control measures are required to prevent the spread of these resistance genes." @default.
