Explaining microbial population genomics through phage predation [PDF]

, 2009
The remarkable diversity of genes within the pool of prokaryotic genomes belonging to the same species or pan-genome is difficult to reconcile with the widely accepted paradigm which asserts that periodic selection within bacterial populations would ...

Isolation of Marine Bacteriophages from Sea Water

NIPPON SUISAN GAKKAISHI, 1971
The author carried out the isolation of marine bacteriophages from sea water and deter-mined the morphological character of five of them. The host bacteria isolated belong to Pseudomonas (2 strains), Vibrio (2), and Flavobacterium (1). The isolated phages are highly specific to the original host and are virulent.

Pseudoalteromonas spp. phages, a significant group of marine bacteriophages in the North Sea [PDF]

Aquatic Microbial Ecology, 2002
The occurrence and distribution of specific bacteriophages of marine Pseudoaltero- monas spp. in the North Sea (North Sea phages) and their genetic relationship to several previously isolated marine phage species from waters of the Helgoland Roads (German Bight, Helgoland phages) were investigated.

Characterization of a cold-active bacteriophage on two psychrophilic marine hosts [PDF]

Aquatic Microbial Ecology, 2006
A cold-active bacteriophage designated 9A was isolated against Colwellia psychrery- thraea Strain 34H at near in situ temperature (-1°C) by enrichment of seawater from an Arctic nepheloid layer, using a newly developed isothermal overlay technique. Phage 9A is classified as a Siphoviridae with a genome size of 80 to 90 kb.

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Fixed points and limit cycles in the population dynamics of lysogenic viruses and their hosts

, 2010
Starting with stochastic rate equations for the fundamental interactions between microbes and their viruses, we derive a mean field theory for the population dynamics of microbe-virus systems, including the effects of lysogeny. In the absence of lysogeny,

Effects of Increased Water Salinity and Temperature on the Development of Rainbow Trout Fry Syndrome (RTFS) Caused by Flavobacterium psychrophilum

Journal of Fish Diseases, Volume 49, Issue 2, February 2026.
ABSTRACT Flavobacterium psychrophilum, the etiological agent of Rainbow Trout Fry Syndrome (RTFS) and Bacterial Coldwater Disease (BCWD), causes varying degrees of disease and mortality in salmonid aquaculture worldwide. Because its treatment relies on the use of antimicrobials, alternative interventions are of environmental and economic interest.

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified
