Molecular characterization of a new class 3 integron in Klebsiella pneumoniae.
Klebsiella pneumoniae FFUL 22K was isolated in April 1999 from the urine of an intensive care unit patient in Portugal. The strain showed an extended-spectrum cephalosporin resistance profile. A typical synergistic effect between cefotaxime or cefepime and clavulanic acid was observed. An Escherichia coli transformant displayed a similar resistance phenotype and harbored a ca. 9.4-kb plasmid (p...
متن کاملPrevalence of Class 1 Integron in Klebsiella Pneumoniae Isolates from Hospitals of Sanandaj, Iran
Background and Aims: Integrons as mobile genetic elements are located on the chromosome or on a plasmid in bacteria. Integrons play a main role in the dissemination of antibiotic resistance genes among different families of bacteria. The aim of this study was to identify the prevalence of class 1 integron in Klebsiella pneumoniae isolates from hospitals of Sanandaj, Kurdistan province, Iran. M...
متن کاملIsolation and partial characterization of a new strain of Klebsiella pneumoniae capable of high 1,3 propanediol production from glycerol
Glycerol is a promising feedstock for microbial cultivation and production of 1,3 propanediol (1,3 PDO). Here we report a newly isolated bacterial strain BA11 from soil, capable of fermenting glycerol to 1,3 PDO, and has been identified to be a strain of Klebsiella pneumoniae. Strain BA11 was fast growing showing peak 1,3 PDO production in 6 h of cultivation with productivity of 1.2 g/...
متن کاملMolecular characterization of multidrug-resistant Klebsiella pneumoniae isolates
Klebsiella pneumoniae is an important cause of healthcare-associated infections worldwide. Selective pressure, the extensive use of antibiotics, and the conjugational transmission of antibiotic resistance genes across bacterial species and genera facilitate the emergence of multidrug-resistant (MDR) K. pneumoniae. Here, we examined the occurrence, phenotypes and genetic features of MDR K. pneum...
متن کاملMolecular characterization of the type 3 (MR/K) fimbriae of Klebsiella pneumoniae.
The expression of type 3 (MR/K) fimbriae by Klebsiella pneumoniae requires the production of at least four polypeptides with molecular masses of 20.5, 25, 34, and 78 kilodaltons. The genes encoding these polypeptides are located on a gene cluster 5,500 base pairs in length. The nucleotide sequence of the major fimbrial structural gene was determined, and its transcription was shown to initiate ...
