Extended – Spectrum Βeta-Lactamase producing strains among clinical isolates has been steadily increasing over the past years. Microorganisms responsible for UTIs such as Escherichia coli and klebsiella 5pp have the ability to produce ESBLs in large quantities. All the strains of klebsiella species in this study were collected from routine clinical samples confirmed by biochemical and other tes...

Klebsiella is one of the pathogens able to form biofilm and then to produce Catheter Associated Infections (CAI). The capability to form biofilm can be considered as a virulence factor. Lactobacilli are included into the potential protective microorganisms to be used for bacteriotherapy to prevent CAI and Urinary tract Infections (UTI). The aim of this work was to isolate Klebsiella strains fro...

2,3-Butanediol (2,3-BDO) has immense industrial applications. Recently, microbial fermentation has emerged as an alternative way to produce this industrially important chemical. Although 2,3-BDO is produced by several microorganisms, the Klebsiella genera has an excellent production compared with other 2,3-BDO-producing microorganisms. In order to produce 2,3- BDO on a large scale, the challeng...

Presence of Bush class C enzymes in uropathogenic strains of Klebsiellapneumoniae & E.coli resistant to extended spectrum cephalosporins is anemerging threat to clinical therapeutics. These resistant strains result inconsiderable treatment failure and cannot be detected by routine antibioticsensitivity screening methods. An effort was therefore made to study AmpC βlactamase ...

BL-S640, a new oral cephalosporin analogue, was evaluated in vitro against 102 gram-negative and 80 gram-positive bacteria. The antimicrobial spectrum was similar to that of previous cephalosporin analogues. Good antimicrobial activity against strains of Escherichia coli, Klebsiella, staphylococci, and streptococci was demonstrated. Relatively poor activity and/or resistance was noted among mos...

Epidemiological analysis of isolates from nosocomial infections caused by Klebsiella pneumoniae was improved by the use of bacteriocins in addition to capsular serotyping. Screening for bacteriocins produced by 77 reference strains for capsular serotyping identified 39 strains, and 8 of these strains were selected as a typing set. Using this set, we found that 241 to 259 (91%) nonepidemic clini...

Many bacteria produce extra cellular polysaccharide (EPS) and in genera such as Klebsiella, Rhizobium, Bacillus and Streptococcus they[Delete] have been well characterized for a number of species and strains. Polysaccharides from plant sources material and their modified forms are important additives in the food industry. The EPS is the use of xanthan in oil industry. The most significant biome...

This study aimed to decolourise different dyes using two Klebsiella strains (Bz4 and Rz7) in different concentrations and incubation conditions. Azo (Evans blue (EB)) and triphenylmethane (brilliant green (BG)) dyes were used individually and in mixture. The toxicity of the biotransformation products was estimated. Both strains had a significant potential to decolourise the dyes in the fluorone...

Fifty-three clinical isolates of Klebsiella and fifty-one clinical isolates of Pseudomonas aeruginosa, twenty-six of which were carbenicillin-(CARB) resistant, were tested for susceptibility to mezlocillin (MEZ), azlocillin (AZL), and piperacillin (PIP), both alone and in combination with tobramycin (TOB) using the microtiter broth diluent method and an inoculum density of 10(6) CFU/ml. The Kle...

The antibacterial interactions of temocillin with other beta-lactams were tested by checkerboard combination in Mueller-Hinton agar against 146 strains of members of the family Enterobacteriaceae, 35 Pseudomonas aeruginosa strains, and 35 Staphylococcus aureus strains. Most combinations showed a moderate degree of synergism. In only one Klebsiella strain was minor antagonism observed between te...
