Potential significance of lysogeny to bacteriophage production and bacterial mortality in coastal waters of the Gulf of Mexico
Article Abstract:
The induction of lysogenic bacteria is unlikely to be the major cause of marine bacterial mortality or phage production in the coastal waters of the western Gulf of Mexico. The addition of mitomycin C causes greater phage production than induction by UV C. Phage production and bacterial mortality are due to the lytic pathway of viral infection rather than induction of lysogenic bacteria. Lysogenic phage production will be an important contributor to total phage production only when the majority of lysogenic cells are induced and lytic production is low.

Genetic diversity in marine algal virus communities as revealed by sequence analysis of DNA polymerase genes
Article Abstract:
Marine virus communities include various groups of MpV-like viruses and also other unknown members of the family Phycodnaviridae. Five genotypes or operational taxonomic units of viruses from the Gulf of Mexico were characterized for their genetic make up. Their restriction fragment length polymorphism banding patterns indicate that all of them come under the family Phycodnaviridae. The combination of ultrafiltration with polymerase chain reaction is useful in amplifying DNA pol genes.

Virus attachment to transparent exopolymeric particles along trophic gradients in the southwestern lagoon of New Caledonia
Article Abstract:
The percentage of viruses associated with transparent exopolymeric particles (TEP) is quantified along trophic gradients in the southwestern lagoon of New Caledonia. The data suggest that the fraction of viruses attached to TEP is highest in areas characterized by a low renewal rate of the water mass and can constitute at times a significant fraction of total virus abundance.
