molecular characterization of klebsiella pneumoniae carbapenemase (kpc)-producing enterobacteriaceae in ontario, canada, 2008-2011.due to the lack of detailed reports of klebsiella pneumoniae carbapenemase (kpc)-producing enterobacteria in ontario, canada, we perform a molecular characterization of kpc-producing enterobacteriaceae submitted to the provincial reference laboratory from 2008 to 2011. susceptibility profiles were accessed by e-test. molecular types of isolates were determined by pulse-field gel electrophoresis (pfge) and multilocus sequence typing. screening of ß-lactamase genes was performed by multiplex pcr a ...201425549365
occurrence and characterization of resistance to extended-spectrum cephalosporins mediated by beta-lactamase cmy-2 in salmonella isolated from food-producing animals in canada.resistance of salmonella to extended-spectrum cephalosporins (escs) is being reported with increasing frequency. in humans, infections with salmonella resistant to escs threaten the efficacy of ceftriaxone, the drug of choice for treating salmonellosis in children. to determine the occurrence of resistance to escs, we examined 8426 strains isolated from food-producing animals in canada in 1994-99 for reduced susceptibility or resistance to ceftriaxone. of the 8 such strains identified (7 from tu ...200212146884
