Type of Research Project
- Clinical Project with Laboratory work
What is the background of the project?
Aquired resistance to b-lactams (mainly carbapenems) among Gram negative pathogens especially Klebsiella pneumoniae and Pseudomonas aeruginosa in hospitals is a growing problem worldwide limiting the clinical utility of several antimicrobials including carbapenems. Of carbapenemases, two major types have been reported up to now, the molecular class B metallo-β-lactamases (MBLs) and the molecular class A K. pneumoniae carbapenemases (KPCs) Accurate detection of these pathogens is necessary to control and prevent their nosocomial transmission. The aim of the present project is to determine the spread of different b-lactamase especially extended spectrum and carbapenemases among b-lactamase-nonsusceptible Gram negative pathogens who are isolated from clinical isolates in AHEPA University Hospital, Thessaloniki, Greece.

All clinical isolates found resistant to b-lactams of 3rd and fourth generation of cephalosporins and/or carbapenems will be phenotypically screened for ESBL and carbapenemase (MBL, KPC, MBL/KPC) production with a combined disk test using meropenem disks without and with EDTA, phenyl-boronic acid (PBA) or both inhibitors. Additionally, in order to detect extended-spectrum-β-lactamases (ESBLs) among cabapenemase-producing strains, the modified CLSI ESBL confirmatory test will be performed using cefotaxime and ceftazidime disks Where necessary, Hodge test will also be applied.

1
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a scientific report
- The student will prepare an abstract
- No specific outcome is expected
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Some experience in basic laboratory techniques (use of micropipettes, bacteriological loops) would be well-come. No legal limitations. There will be theoretical and practical teaching (lectures and by the bench)
Are there any legal limitations in the student’s involvement
No
