Flavobacterium columnare in common carp (Cyprinus carpio) and rainbow trout (Oncorhynchus mykiss): antimicrobial susceptibility and interplay with its host
|Research area||Unravelling the impact of chronic stress across vertebrates|
|Research topic||Microbial endocrinology, interaction between bacteria, glucocorticoids and|
the stress level in fish
|Species||Bacteria Flavobacterium columnare|
The research goal is to use scale cortisol as a reflection of the fish’s exposure to chronic stress using a bacterial infection with the fish pathogen Flavobacterium columnare eliciting skin and gill disease as a stressor as well as contribute to the elucidation of the enigma of the interplay between bacterial pathogens, glucocorticoids and the hypothalamic-pituitary-interrenal (HPI) axis. The engendered data will provide fundamental research insights into the bacterial pathogen acting as a stressor and will facilitate the nowadays imperative sustainable development of aquaculture.
