reevaluating practice changes: return to standard precautions after an outbreak of multidrug-resistant klebsiella oxytoca.	change in medical practice is usually made to solve immediate problems. the continued use of these changes should then be reevaluated. following an outbreak of k. oxytoca in our neonatal intensive care unit (nicu), glove use for all patient contact was mandated. we evaluated the need for continued glove use after resolution of the outbreak. no change in colonization patterns was seen after returning to standard precautions, and, as a secondary benefit, financial savings resulting from decreased ...	2000	10646301
epidemiology of conjugative plasmid-mediated ampc beta-lactamases in the united states.	a sample of 752 resistant klebsiella pneumoniae, klebsiella oxytoca, and escherichia coli strains from 70 sites in 25 u.s. states and the district of columbia was examined for transmissibility of resistance to ceftazidime and the nature of the plasmid-mediated beta-lactamase involved. fifty-nine percent of the k. pneumoniae, 24% of the k. oxytoca, and 44% of the e. coli isolates transferred resistance to ceftazidime. plasmids encoding ampc-type beta-lactamase were found in 8.5% of the k. pneumon ...	2004	14742206
emergence of serine carbapenemases (kpc and sme) among clinical strains of enterobacteriaceae isolated in the united states medical centers: report from the mystic program (1999-2005).	among 8885 enterobacteriaceae tested in the 1999 to 2005 period as part of the usa meropenem yearly susceptibility test information collection (mystic) program, 51 strains with increased imipenem and meropenem mic values (> or =2 microg/ml) were detected. bla(kpc) was identified from 28 klebsiella pneumoniae from 3 medical centers in the new york city area (8 ribotypes), 2 klebsiella oxytoca from arkansas (same ribotype), 7 citrobacter freundii (6 from new york [5 ribotypes] and 1 from delaware) ...	2006	17020798
genetic organization of transposase regions surrounding blakpc carbapenemase genes on plasmids from klebsiella strains isolated in a new york city hospital.	carbapenem-resistant klebsiella strains carrying klebsiella pneumoniae carbapenemases (kpc) are endemic to new york city and are spreading across the united states and internationally. recent studies have indicated that the kpc structural gene is located on a 10-kb plasmid-borne element designated tn4401. fourteen klebsiella pneumoniae strains and one klebsiella oxytoca strain isolated at a new york city hospital in 2005 carrying either bla(kpc-2) or bla(kpc-3) were examined for isoforms of tn44 ...	2009	19258268
complete nucleotide sequence of the incn plasmid pkox105 encoding vim-1, qnrs1 and shv-12 proteins in enterobacteriaceae from bolzano, italy compared with incn plasmids encoding kpc enzymes in the usa.	we determined the complete nucleotide sequence of pkox105, a 54 641 bp plasmid from a klebsiella oxytoca strain that was isolated from a resident of a long-term-care facility in bolzano, italy.	2010	20656680
sources of klebsiella and raoultella species on dairy farms: be careful where you walk.	klebsiella spp. are a common cause of mastitis, milk loss, and culling on dairy farms. control of klebsiella mastitis is largely based on prevention of exposure of the udder to the pathogen. to identify critical control points for mastitis prevention, potential klebsiella sources and transmission cycles in the farm environment were investigated, including oro-fecal transmission, transmission via the indoor environment, and transmission via the outdoor environment. a total of 305 samples was coll ...	2011	21257074
