New lytic and new temperate Staphylococcus hyicus phages.
A novel lytic phage with a broad host range was isolated from pig faeces and the complete genome was subsequently sequenced. The phage was found to lyse Staphylococcus hyicus, S. pseudintermedius, S. schleiferi and S. warneri, generating approximately 27 PFU per infected S. hyicus cell. The phage has an isometric head of 42 ± 2 nm in diameter and a noncontractile tail of 114 ± 9 nm long. The genome is 53,660 bp in size and consists of 79 predicted ORFs and one tRNAArg gene. The phage has been classified within the Caudoviricetes, specifically the Chaseviridae family. Its broad host range and absence of harmful genes make it suitable for use in phage therapy. In addition, a novel temperate phage was discovered that was spontaneously released from a S. hyicus isolate Pel11 from a pig with exudative epidermitis. This novel temperate phage differs from the known temperate phages in S. hyicus strains NCTC10350, MM2101 or 83/7-1B, representing a novel pathogenicity element in the S. hyicus genome.
期刊介绍：
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
