Bacteriophage IKe: A species of filamentous phage in the genus INOVIRUS, family INOVIRIDAE. They are specific for enterobacteria that contain an IncN plasmid.Bacteriophages: Viruses whose hosts are bacterial cells.Cyclonic Storms: Non-frontal low-pressure systems over tropical or sub-tropical waters with organized convection and definite pattern of surface wind circulation.Bacteriophage T4: Virulent bacteriophage and type species of the genus T4-like phages, in the family MYOVIRIDAE. It infects E. coli and is the best known of the T-even phages. Its virion contains linear double-stranded DNA, terminally redundant and circularly permuted.Coliphages: Viruses whose host is Escherichia coli.Bacteriophage lambda: A temperate inducible phage and type species of the genus lambda-like viruses, in the family SIPHOVIRIDAE. Its natural host is E. coli K12. Its VIRION contains linear double-stranded DNA with single-stranded 12-base 5' sticky ends. The DNA circularizes on infection.
