We investigated the antimicrobial resistance profile and the occurrence of Klebsiella pneumoniae carbapenemase (KPC)-producing Gram-negative rods in sewage samples obtained from a Brazilian teaching(More)
The emergence of metallo-beta-lactamase (MBL)-producing isolates is a challenge to routine microbiology laboratories, since there are no standardized methods for detecting such isolates. The aim of(More)
The mechanisms involved in the uncommon resistance phenotype, carbapenem resistance and broad-spectrum cephalosporin susceptibility, were investigated in 25 Pseudomonas aeruginosa clinical isolates(More)
The combined disk assay has been used for detection of metallo-beta-lactamase-producing isolates. We have observed that the size of inhibition zones produced by many(More)
OBJECTIVE The main objective of this study was to comparatively evaluate the performance of M.I.C.E. and Etest methodologies to that of agar dilution for determining the antimicrobial susceptibility(More)
