Genomic Analysis of a New Freshwater Cyanophage Lbo240-yong1 Suggests a New Taxonomic Family of Bacteriophages.

A worldwide ecological issue, cyanobacterial blooms in marine and freshwater have caused enormous losses in both the economy and the environment. Virulent cyanophages-specifically, infecting and lysing cyanobacteria-are key ecological factors involved in limiting the overall extent of the population development of cyanobacteria. Over the past three decades, reports have mainly focused on marine and cyanophages, while information on freshwater cyanophages remained largely unknown.

Novel Phage Ahy-Yong1 and Its Protective Effects against in Brocade Carp ( Koi).

is a zoonotic pathogen and an important fish pathogen. A new lytic phage, Ahy-yong1, against multi-antibiotic-resistant pathogen was isolated, identified, and tentatively used in therapy. Ahy-yong1 possesses a head of approximately 66 nm in diameter and a short tail of approximately 26 nm in length and 32 nm in width.

is a major harmful cyanobacterium causing water bloom worldwide. Cyanophage has been proposed as a promising tool for cyanobacterial bloom. In this study, FACHB-1326 was used as an indicator host to isolate cyanophage from Lake Taihu.

Genome sequence of the novel freshwater Microcystis cyanophage Mwe-Yong1112-1.

The freshwater cyanophage Mwe-Yong1112-1 was isolated using Microcystis wesenbergii as a host and found to have an icosahedral head, about 45 nm in diameter, and a flexible tail, approximately 133 nm in length and 4.5 nm in width. The complete genome of the cyanophage is 39,679 bp in length with a G+C content of 66.

A Novel Freshwater Cyanophage, Mae-Yong924-1, Reveals a New Family.

Cyanobacterial blooms are a worldwide ecological issue. Cyanophages are aquatic viruses specifically infecting cyanobacteria. Little is known about freshwater cyanophages.

First Characterization of a Phage Reveals Extraordinarily Large Burst Size and Unusual Plaque Polymorphism.

A unique lytic phage infecting was isolated and identified. phage Ca belongs to the family Autographiviridae, possessing an icosahedral head with a diameter of 55 nm and a short non-contractile tail. Unusually, the burst size of phage Ca of 10,292 ± 1,097 plaque-forming units (PFUs)/cell is much larger than other dsDNA phages reported before.
