A new temperate phage of streptomyces venezuelae: morphology, DNA molecular weight and host range of SV2. 1981

C Stuttard, and M Dwyer

A new, narrow host range temperate phage, SV2, was isolated from soil. It lysogenized and lysed strains of Streptomyces venezuelae and seemed to be specific for this species. In general morphology, the virions were typically lambdoid, but had unusually ringed tails similar to those of some rare phages isolated from hosts belonging to different bacterial genera. The molecular weight of double-stranded linear SV2 DNA, estimated at about 24 X 10(6), was lower than the published values for other Streptomyces phages.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D004279	DNA, Viral	Deoxyribonucleic acid that makes up the genetic material of viruses.	Viral DNA
D001435	Bacteriophages	Viruses whose hosts are bacterial cells.	Phages,Bacteriophage,Phage
D012988	Soil Microbiology	The presence of bacteria, viruses, and fungi in the soil. This term is not restricted to pathogenic organisms.	Microbiology, Soil
D013302	Streptomyces	A genus of bacteria that form a nonfragmented aerial mycelium. Many species have been identified with some being pathogenic. This genus is responsible for producing a majority of the ANTI-BACTERIAL AGENTS of practical value.
