| first isolation of a vim-producing klebsiella pneumoniae from a seven-year-old child in venezuela. | vim-type metallo-betalactamases (mbls) exhibit hydrolytic activity against most betalactam antibiotics, including carbapenems. so far, vim-type-producing klebsiella pneumoniae isolates had not been reported in latin america. | 2008 | 19738358 |
| frequency and diversity of ctx-m enzymes among extended-spectrum beta-lactamase-producing enterobacteriaceae isolates from caracas, venezuela. | ctx-m-type extended-spectrum beta-lactamase (esbl)-producing enterobacteriaceae have been previously reported in venezuela. we assessed the frequency and diversity of ctx-m enzymes among 97 esbl-producing enterobacteriaceae isolates as well as to establish the genetic relationship among ctx-m producers collected from six hospitals in caracas. polymerase chain reaction (pcr) assays identified the bla(ctx-m) genes in 42 isolates (43.3%). the bla(ctx-m-1) group was the most common in escherichia co ... | 2013 | 23067200 |
| molecular characterization of kpc-producing klebsiella pneumoniae isolated from patients in a public hospital in caracas, venezuela. | klebsiella pneumoniae carbapenemase (kpc)-producing bacteria are amongst the most important causative agents of nosocomial infections worldwide. isolates of this bacterium have been identified in venezuela but little is known about their local spread. the aim of this study was to perform the molecular characterization of kpc-producing strains isolated from 2012 to 2013 in a public hospital in caracas, venezuela. | 2017 | 28291671 |
