CARBAPENEM RESISTANCE DISSERTATION

Urinary tract infections cystitis, pyelonephritis etc. Even though, iutA gene region was reported in high incidence in complicated urinary tract infection compared to control group and acute cholangite. Journal of Microbiology ; In this study, when the carbapenem and virulence gene profiles are evaluated and 24 types of virulence profiles are identified Table 3. Although no statistically important relation found between carbapenem resistance and virulence factors in this study, the effect of beta-lactam resistance in virulence is known. Carbapenem resistance in Turkey: The primers used in this study are listed in Table 1.

Escherichia coli virulence factors. The genes encoding the MBLs are usually found on integrons, often embedded in functional transposons. Also, serotype O12 isolates from Greece harboring genes encoding different VIM-variants were found to belong to the same sequence type. OmpC and the sigma E regulatory pathway are involved in adhesion and invasion of the Crohn’s disease-associated Escherichia coli strain LF Klebsiella pneumoniae and Escherichia coli are pathogens belonging to the Enterobacteriaceae family. Marlen Adler ; Uppsala universitet. The results of the study appear to indicate that fimA and afa genes correlate with carbapenem susceptibility, the relations of fimA with urinary tract infections and pap with complicated urinary tract infections.

International Journal of Medical Microbiology ; DNA sequencing of oprD, pbp-2, pbp-3 and some of the efflux pump regulatory genes was conducted in selected isolates.

PFGE and RAPD did not cluster all isolates that were found to belong to the same clonal complex according to MLST, and the latter is therefore probably best suited for studies of international epidemiology.

Siderophores are the most important virulence factor supporting bacterial infection in tissues and blood, in case of there is iron deficiency. The primers used in this study are listed carbaprnem Table 2.

Down-regulation of OprD, which is the primary porin for carbapenem uptake, confers resistance to both imipenem and meropenem, although the latter is affected less.

Another virulence gene region found with high incidence in our study was fimA which is related to Type Diesertation fimbriae. Also, the frequency of virulence gene regions in E. International Journal of Antimicrobial Agents ;31, Search for dissertations about: Journal of Microbiology ; Although no statistically important relation found between carbapenem resistance and virulence factors in this study, the effect of beta-lactam resistance in virulence is known. Distribution of uropathogenic virulence genes in Escherichia coli isolated from patients with urinary tract infection.

In this study, when the carbapenem and virulence gene profiles are evaluated and 24 types of virulence profiles are identified Table 3. Siderophores in urinary tract infections are virulence factors frequently found in most pathogenic types of E.

Evaluation of a chromogenic agar medium for the detection of extended-spectrum beta-lactamase-producing Enterobacteriaceae. Klebsiella pneumoniae cwrbapenem Escherichia coli are pathogens belonging to the Enterobacteriaceae family.

Clinical Microbiology and Infection ; Klebsiella pneumoniae and Escherichia coli: Studies of transferable carbapenem resistance showed that the serotype O11 isolates from Italy and Greece belonged to the same clonal complex, according to MLST. Existing mechanisms are mainly due to acquired carbapenemases or the combination of ESBL-production and reduced outer membrane permeability.

Services on Demand Journal. S-fimbria-encoding determinant sfaI is located on pathogenicity island III of uropathogenic Escherichia coli strain ABSTRACT In this study, fifty Escherichia coli strains were analyzed by multiplex polymerase chain reaction for the genes expressed carbapenemase and virulence factors in order to determine the presence of carbapenemase and nine virulence factors and investigate the association between these two characteristics.

Carbapenem resistance in Pseudomonas aeruginosa. The least common virulence gene region among strains is hly gene region responsible for hemolysis. They can cause infections ranging from uncomplicated urinary tract infection to severe bloodstream infection BSI.

The aim of the study is to determine the presence of carbapenemase and virulence factors of E. The mix for the detection of other groups afa-sfa-fimA, hly-iroN-aer-cnf1-iutA was at the same concentrations.
