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
travel-related carbapenemase-producing gram-negative bacteria in alberta, canada: the first 3 years.we describe here the characteristics of alberta, canada, patients with infections or colonizations with carbapenemase-producing gram-negative bacteria during 2010 to 2013 that were linked to recent travel outside canada. antimicrobial susceptibility was determined by broth microdilution, and isolates were characterized using pcr, sequencing, and multilocus sequencing typing. a broth mating study was used to assess the transferability of resistance plasmids, which were subsequently characterized. ...201424599977
