Pseudo-outbreak of imipenem-resistant Acinetobacter baumannii resulting from false susceptibility testing by a rapid automated system.
Introduction of the Vitek GNS-506 susceptibility testing cards in the Hippokration General Hospital, Thessaloniki, Greece, resulted in an apparently high prevalence of imipenem-resistant Acinetobacter baumannii. When 35 of these isolates were further tested by disk diffusion, broth microdilution, and agar dilution assays, 32 were imipenem sensitive by all tests and three were sensitive or inter...
متن کاملRapid and overnight microdilution antibiotic susceptibility testing with the Sensititre Breakpoint Autoreader system.
The Sensititre Breakpoint Autoreader system (SBAS) is a broth microdilution method with one to three concentrations of each antibiotic and innovative fluorescence technology to define inhibitory endpoints. We tested 248 gram-negative bacilli and 80 gram-positive cocci using both the rapid (5 h) and overnight (18 h) SBAS procedures. Inhibitory endpoints were also determined by visual inspection ...
متن کاملComparison of Disc Diffusion, Broth Microdilution and Modified Hodge Test Susceptibility Testing Of Escherichia coli Isolates to Beta-Lactam Antibiotics
ABSTRACT Background and Objective: One of the main tasks of clinical microbiology laboratories is to determine antibiotic resistance profiles in common pathogens and ensure the selection of effective antibiotics for certain infections. The aim of this study was to compare the methods of disk diffusion, broth microdilution and modified Hodge test i...
متن کاملEvaluation of the Sceptor microdilution antibiotic susceptibility testing system: a collaborative investigation.
A multiwell, dried antimicrobial agent susceptibility test system, Sceptor (BBL Microbiology Systems, Cockeysville, Md.), was tested. The system was compared directly with a reference microdilution method by using two collections of stock cultures and 305 fresh clinical isolates. Sceptor was found to be in agreement (+/- log2 dilution) with the reference microdilution method in 96.9 to 98.3% of...
متن کاملMicrodilution technique for antimicrobial susceptibility testing of anaerobic bacteria.
A microdilution technique using commercially available media and materials was developed and used to determine the minimal inhibitory concentrations (MICs) of clindamycin, chloramphenicol, tetracycline, minocycline, ampicillin, carbenicillin, cephalothin, and gentamicin for 101 anaerobic isolates. Representative strains of Bacteroides, Clostridium, Fusobacterium, Peptococcus, and Peptostreptoco...
