conclusions ctx-m was the most prevalent esbl genotype in uropathogenic e. coli (upec) isolated from uti. in addition, a high frequency of qnr genes among esbl-producing e. coli was identified in this study. in order to avoid treatment failures, we recommend using phenotypic and molecular methods to diagnose these enzymes and qnr genes. results the highest sensitivity was seen to imipenem (96.7...

conclusions the impact of sugars and other factors on biofilm formation can vary depending on the type of bacteria present. results results showed that the presence of sugars has no effect on the bacterial growth rate; all three concentrations of sugars were hydrophilic and demonstrated a high affinity toward binding to the surfaces. background bacteria utilize various methods in order to live ...

conclusions our present study shows that sugar beet molasses is a source of plp and l-ser; and hence, suggests the general application of the approach to produce l-trp more economically. results consequently, the potassium phosphate buffer system was considered as the suitably buffered reaction medium. the concentration of l-trp produced in reaction medium was 0.3 mm and 0.12 mm for glucose and...

conclusions reteplase was expressed in e. coli top 10 after activation of pbad/giiia promoter region by arabinose and optimized. results the obtained recombinant plasmid was sequenced to confirm the presence and correct framing of reteplase gene regarding the expression of reteplase. maximum production of this enzyme was obtained under the following condition: 0.0002% l-arabinose at 37°c for 2 ...

background development of antibiotic resistance among pathogenic bacteria motivates the researchers to search for newer antimicrobial agents. objectives in the present study, antibacterial effects of cuminum cyminum linn. essential oil against multidrug resistant (mdr) escherichia coli strains isolated from urinary tract infections were studied, using microdilution method. materials and methods...
