Autor: Heidi M. T. Kunttu, Anniina Runtuvuori-Salmela, Mathias Middelboe, Jason Clark, Lotta-Riina Sundberg

Publikováno v: Antibiotics, Vol 10, Iss 8, p 914 (2021)

Viruses of bacteria, bacteriophages, specifically infect their bacterial hosts with minimal effects on the surrounding microbiota. They have the potential to be used in the prevention and treatment of bacterial infections, including in the field of f

Publikováno v: Environmental Microbiology Reports. 4:398-402

Summary Flavobacterium columnare, causing columnaris disease, was isolated for the first time from free water and biofilms in the environment outside fish farms. Fourteen isolates were found from Central Finland from a river by a water intake of a sa

Publikováno v: Journal of Applied Microbiology. 111:1319-1326

Aims: Colony morphology variants of fish pathogenic Flavobacterium columnare were studied to clarify the role of colony morphology change in the virulence of the bacterium. Typical rhizoid colony (Rz) variants are virulent and moderately adherent, no

Autor: E. Ilmari Jokinen, Heidi M. T. Kunttu, L.-R. Suomalainen, E. Tellervo Valtonen

Publikováno v: Epidemics. 1:96-100

Fish farming creates conditions where disease transmission is enhanced and antibiotic treatments are commonly used to cure bacterial diseases to prevent severe losses due to infections. Ability to persist in such an environment has been suggested to
