New Vista into Origins of Viruses from a Prototypic ssDNA Phage

N. Kejzar, E. Laanto, I. Rissanen, V. Abrishami, M. Selvaraj, S. Moineau, J. Ravantti, L.-R. Sundberg, J. T. Huiskonen

The paper characterizes a lipid-containing ssDNA phage, {Phi}CjT23, and suggests it represents a model for the last common ancestor of ssDNA and dsDNA viruses in the Bamfordvirae.

Rich resource environment of fish farms facilitates phenotypic variation and virulence in an opportunistic fish pathogen

K. Pulkkinen, T. Ketola, J. Laakso, J. Mappes, L.-R. Sundberg

The paper shows that fish farm environments promote phenotypic variation and virulence in Flavobacterium columnare, with rough morphotypes growing faster and reversing to rhizoid types in contact with fish.

Mucin induces CRISPR-Cas defence in an opportunistic pathogen

G. M. Almeida, V. Hoikkala, J. J. Ravantti, N. Rantanen, L.-R. Sundberg

The paper shows that mucin enhances CRISPR spacer acquisition in Flavobacterium columnare during phage infection, especially under low nutrient conditions and in the presence of competitor bacteria.

Bacteriophage Resistance Affects Flavobacterium columnare Virulence Partly via Mutations in Genes Related to Gliding Motility and Type IX Secretion System

H. M. Kunttu, A. Runtuvuori-Salmela, K. Sundell, T. Wiklund, M. Middelboe, L. Landor, R. Ashrafi, V. Hoikkala, L.-R. Sundberg

This study shows that phage resistance in Flavobacterium columnare reduces virulence, making phage therapy viable for treating columnaris disease in aquaculture.

Prevalence of genetically similar Flavobacterium columnare phages across aquaculture environments reveals a strong potential for pathogen control

A. Runtuvuori-Salmela, H. M. Kunttu, E. Laanto, G. M. Almeida, K. Makela, M. Middelboe, L.-R. Sundberg

The paper characterizes Flavobacterium columnare phages from aquaculture environments, showing genetic similarity across locations and potential for phage therapy.

Cooperation between CRISPR-Cas types enables adaptation in an RNA-targeting system

V. Hoikkala, J. J. Ravantti, C. Diez-Villasenor, M. Tiirola, R. Conrad, M. J. McBride, L.-R. Sundberg

The paper shows that an RNA-targeting CRISPR-Cas subtype VI-B locus can acquire spacers using machinery from a DNA-targeting II-C locus in the same bacterium.

Bacteriophage adherence to mucus mediates preventive protection against pathogenic bacteria

G. M. Almeida, E. Laanto, R. Ashrafi, L.-R. Sundberg

This study shows bacteriophages can bind to mucus and protect fish from bacterial infections, suggesting mucus interactions are important for phage-bacteria dynamics and potential phage therapy.
