Lysogeny (bacteria containing inducible prophages) and lytic viral infection (bacteria in a lytic stage of infection) were investigated at the community level in contrasting marine environments such as estuarine versus offshore waters, surface versus deep waters, and oxic versus anoxic waters in the Mediterranean and Baltic Seas. The frequency of lysogenic cells (FLC) in bacterioplankton communities ranged from not detectable to 84% as estimated by prophage induction due to mitomycin C, and…

Virioplankton distribution and activity in a tropical eutrophicated bay

Moderate Seasonal Dynamics Indicate an Important Role for Lysogeny in the Red Sea

Despite the fact that the Red Sea might be perceived as stable, warm and saline, relatively modest changes in seasonal conditions were associated with large swings in the prevalence of lysogeny, and no induction was measurable in spring when bacterial abundances were highest.

Virus-Bacterium Interactions in Water and Sediment of West African Inland Aquatic Systems

The results support the paradigm that aquatic viruses are ubiquitous and may have moved between the two compartments of the shallow systems examined and indicates that the intensity of virus-bacterium interactions in benthic habitats may lower than the intensity in the adjacent bodies of water.

Low effect of viruses on bacteria in deep anoxic water and sediment of a productive freshwater reservoir

There was a remarkably low viral influence on heterotrophic bacteria in the anoxic waters and overlying sediments of Lake Grangent, where recurrent shift from summer planktonic to winter benthic phases in cyanobacterial blooms is typical.

Ocean acidification and viral replication cycles: Frequency of lytically infected and lysogenic cells during a mesocosm experiment in the NW Mediterranean Sea

Viral activities and life cycles in deep subseafloor sediments.

Viruses are highly abundant in marine subsurface sediments and can even exceed the number of prokaryotes. However, their activity and quantitative impact on microbial populations are still poorly…

To kill or not to kill: The balance between lytic and lysogenic viral infection is driven by trophic status

Investigation of spatiotemporal patterns in lytic and lysogenic viral infection using water samples collected on the Canadian Arctic Shelf demonstrated the important role of viruses in bacterial mortality and carbon cycling in the Arctic Ocean, and showed how their effect is influenced by trophic status.

Effect of viruses on marine stramenopile (MAST) communities in an oligotrophic coastal marine system

It is indicated that viruses can negatively affect the HF community either directly via lysis of protists or indirectly viaLysis of bacteria, and highlight the interactions between, virus, bacteria and protists.

Genetic richness of vibriophages isolated in a coastal environment.

The VpV population within the Strait of Georgia is a highly diverse mixture of phenotypes and genotypes, and the major determinant of phenotypic (host-range) and genetic richness (by the DP-RAPD assay) was not geography, but the source environment from which the VpVs originated.

Enhanced viral production and virus-mediated mortality of bacterioplankton in a natural iron-fertilized bloom event above the Kerguelen Plateau

The present study suggests viruses to be more important for bacterial mortality within the bloom and dominate over grazing of heterotrophic nanoflagellates (HNFs) during the late bloom phase.

Distribution of viruses and their potential effect on bacterioplankton in an oligotrophic marine system

The percent of total bacterial mortality due to viral lysis in the oligotrophic northwestern Mediterranean was low, certainly much lower than 20%.

Potential significance of lysogeny to bacteriophage production and bacterial mortality in coastal waters of the gulf of Mexico

If mitomycin C induces all or the majority of lysogenized cells, the results imply that lysogenic phage production is generally not an important source ofphage production or bacterial mortality in the coastal waters of the western Gulf of Mexico.

Significance of Lysogeny in the Marine Environment: Studies with Isolates and a Model of Lysogenic Phage Production

A mathematical model based on viral and bacterial abundance and production rates suggests that, under normal conditions, lysogenic viral production contributes less than 0.02% of total viral production, suggesting that lysogens in the marine environment may serve as a source of viruses and only contribute significantly to viral production during natural induction events.

Seasonal and Diel Abundance of Viruses and Occurrence of Lysogeny/Bacteriocinogeny in the Marine Environment

The results indicated that the viral population in Tampa Bay had a strong seasonal pattern with the highest concentrations in the summer and lowest in the winter, and dissolved DNA concentrations displayed diel rhythmicity, suggesting that viruses were not the main source of dissolved DNA.

Significance of Viral Lysis and Flagellate Grazing as Factors Controlling Bacterioplankton Production in a Eutrophic Lake

The high mortality of bacterioplankton due to viral lysis in anoxic water indicates that a significant portion of bacterial production in the metalimnion and hypolimnions is cycled in the bacterium-virus-DOM loop, which has major implications for the fate and cycling of organic nutrients in lakes.

Viruses and protists cause similar bacterial mortality in coastal seawater

It is believed the loss of bacteria to viruses reflects a significant dissipation of energy in this ecosystem and that viruses and protists contribute similarly to bacterial mortality.

Virioplankton: Viruses in Aquatic Ecosystems

Novel applications of molecular genetic techniques have provided good evidence that viral infection can significantly influence the composition and diversity of aquatic microbial communities, supporting the hypothesis that viruses play a significant role in microbial food webs.

Abundance and production of bacteria and viruses in the Bering and Chukchi Seas

The distribution, abundance, and production of viruses and bactena were investigated during an August to September 1992 cruise aboard the RV 'Alpha Helix' in the Bering and Chukchi Seas and suggest viruses to be a ubiquitous and dynamic feature and a significant source of bacterial mortality in Arct~c marine microbial communities.

Distribution of Viruses and Dissolved DNA along a Coastal Trophic Gradient in the Northern Adriatic Sea

The distribution of viral and other microbial abundances as well as the concentrations of dissolved DNA along a trophic gradient in the northern Adriatic Sea were determined and some kind of interaction between heterotrophic nanoflagellates and viruses is proposed, concluding that viral activity may play a significant role in food web structure under changing trophIC conditions.
