Flavobacterium columnare in common carp (Cyprinus carpio) and rainbow trout (Oncorhynchus mykiss): antimicrobial susceptibility and interplay with its host

StressChron Framework:

Project code 043
Acronym CORTPATH
Role Co-coordinator
Research area Unravelling the impact of chronic stress across vertebrates
Research topic Microbial endocrinology, interaction between bacteria, glucocorticoids and the stress level in fish
Vertebrate Fish
Species Bacteria Flavobacterium columnare

Abstract:

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.
