English Abstract Crohn's disease together with ulcerative colitis, is a type of inflammatory bowel disease (IBD) with increasing incidence and prevalence in developed countries. IBD is an immunologically mediated multifactorial disease and it's mechanism of action is still unknown. Current well- established treatment targets the inflammation with corticosteroids and immunosuppressive drugs. Apart from the intestinal inflammation, which is the primary target of the treatment, patients are characteristically afflicted with intestinal dysbiosis. Therefore, possible interventions might be an adjuvant or biological therapy. Adjuvant therapy directly aims the microbiota with probiotics, whereas the target of biological therapy is TNF-α, a pro- inflammatory cytokine excessively secreted by macrophages. The aim of this thesis is to evaluate intestinal microbiota composition changes in IBD patients with regard to courses of adjuvant and biological therapy. Bacterial diversity was analyzed using three different DNA extraction techniques. Rapid beat beating + column (RBB+C) was chosen for analyzing patient samples, as it showed the highest DNA yield and the highest DNA purity. Primarily the bacterial diversity was analyzed using degradation gradient gel electrophoresis (DGGE) with subsequent sequencing of bands of...
