Biochemical characterization of SHV-55, an extended-spectrum class A beta-lactamase from Klebsiella pneumoniae.
We biochemically characterized the Klebsiella pneumoniae extended-spectrum SHV-55 enzyme carrying the amino acid substitutions Tyr73Phe (as in SHV-28) and Gly2383Ser and Glu2403Lys (both found in SHV-5) identified in a previous study (5). The SHV-55 extended-spectrum -lactamase differed from SHV-5 only in the signal peptide region (1). The blaSHV-55 gene was obtained as described by Mendonça et...

Objective: In this work we report the molecular characterization of ß-lactam antibiotics resistance conferred by genes contained in plasmids from enterobacteria producing extended-spectrum ß-lactamases (ESBL). Material and Methods: Fourteen enterobacterial clinical isolates selected from a group of strains obtained from seven different hospitals in Mexico during 1990-1992 and 1996-1998 were ana...

متن کاملIsolation from blood culture of a Leclercia adecarboxylata strain producing an SHV-12 extended-spectrum beta-lactamase.
We report on the first isolation of an extended-spectrum beta-lactamase-producing Leclercia adecarboxylata strain from the bloodstream in a 58-year-old man with acute myeloid leukemia. The strain, resistant to ceftazidime, cefotaxime, and aztreonam, produces the SHV-12 beta-lactamase, one of the most common variants found in Italian nosocomial isolates of Enterobacteriaceae.
متن کاملExtended-spectrum beta-lactamase genes of Klebsiella pneumoniae strains in Taiwan: recharacterization of shv-27, shv-41, and tem-116.
Klebsiella pneumoniae causing primary liver abscess (PLA) is emerging. This study identified the beta-lactamases genes of K. pneumoniae isolates in Taiwan. The susceptibilities of beta-lactam antibiotics of 30 K. pneumoniae strains associated with primary liver abscess and 30 noninvasive strains were analyzed. The beta-lactamase genes of randomly selected 24 strains from community-acquired infe...
