About Isak Demirel

My PhD studies, which I finished May 2014 were focused on characterising the host-pathogen interaction of uropathogenic Escherichia coli (UPEC) during a urinary tract infection. During the latter part of my studies, the aim was to investigate if the immune response evoked by extended spectrum beta lactamase (ESBL) isolates differs from non-ESBL-producing uropathogenic E. coli. My research aimed to characterize the virulence patterns of ESBL isolates and to identify new novel treatment options to cope with the globally increased antibiotic resistance. In 2015, I was awarded a position as a post doctorate fellow in iRiSC (Inflammatory Response and Infection Susceptibility Centre) at Örebro University. I will continue to study host-pathogen interactions during my postdoc with focus on UPECs ability to induce/subvert the inflammasomes.
