A conjugative IncL/M plasmid (pSEM) conferring resistance to gentamicin, amikacin, kanamycin, sulfonamides, and expanded-spectrum cephalosporins was found in pathogenic strains of Salmonella enterica serotype Typhimurium. Resistance to aminoglycosides was encoded by a sul1-type class 1 integron (In-t3). An extended-spectrum beta-lactamase gene, bla(SHV-5), was identified 3. 5 kb downstream of t...

Super Hi-Vision’ (SHV) is promising as a future form of television. It is an ultra-high definition TV system that has 16 times the number of pixels of HDTV and employs a 22.2 multichannel sound system. It offers superior presence and gives the impression of reality. The information bitrates of the current prototypes range from 24 to 72 Gbit/s, and a fiber optic transmission system is needed to ...

Three families of chromosomally encoded beta-lactamases have been identified so far in Klebsiella pneumoniae clinical isolates: SHV (7), LEN (1), and very recently, OKP (5). These enzymes are closely related to OHIO-1 (10). We determined the sequences of the bla genes of nine isolates of K. pneumoniae producing a penicillinase with an isoelectric point different from 7.6, the pI of the most com...

background & objectives:extended-spectrum-b-lactamase (esbl)-producing strains of klebsiella pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. this study was performed to determine the prevalence of esbl-producing k. pneumonia and to evaluate the frequency o...
