H. Bello et al., ACTIVITY OF SELECTED BETA-LACTAMS, CIPROFLOXACIN, AND AMIKACIN AGAINST DIFFERENT ACINETOBACTER-BAUMANNII BIOTYPES FROM CHILEAN HOSPITALS, Diagnostic microbiology and infectious disease, 28(4), 1997, pp. 183-186
The activity of some third generation cephalosporins, aztreonam, imipe
nem, ciprofloxacin, and amikacin against isolates of Acinetobacter bau
mannii of various biotypes has been studied. The isolates, independent
ly of the biotype, exhibited a broad multiresistance against cephalosp
orins. Ceftazidime was the most active and cefoperazone tile least act
ive compound. Aztreonam also showed low activity and no imipenem-resis
tant strains were found. Ciprofloxacin and amikacin were somewhat move
active than cephalosporins, but resistant isolates were also frequent
. Isolates of Biotypes 9 and 8 exhibited broader multiresistance than
those of Biotype 6 and ''other.'' (C) 1997 Elsevier Science Inc.
