'''''Zindervirus''''' (synonym ''SP6-like viruses'', ''Sp6likevirus'') is a genus of [[Biology:Virus|virus]]es in the family ''[[Biology:Autographiviridae|Autographiviridae]]'', within the subfamily ''Molineuxvirinae''. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently three species in this genus, including the type species ''Salmonella virus SP6''.<ref name=ViralZone>{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/viralzone/all_by_species/708.html|publisher=ExPASy|access-date=17 February 2015}}</ref><ref name=ICTV /><ref name=NCBI />

==Taxonomy==
The following species are recognized:<ref name=ICTV />
*''Escherichia virus UAB78''
*''Salmonella virus BP12B''
*''Salmonella virus SP6''

==Structure==
Zinderviruses are [[Biology:Viral envelope|non-enveloped]], with a head and tail. The head is approximately 60 to 65&nbsp;nm in diameter. The tail is non-contractile and has six prominent spikes.<ref name=ViralZone />

==Genome==
Four of the five viruses' genomes have been fully sequenced and are available on NCBI's website (only Enterobacteria phage K5 is unavailable). They range between 43k and 46k nucleotides, with 52 to 62 proteins. All four complete genomes, as well as several additional "unclassified" virus genomes, are available [https://www.ncbi.nlm.nih.gov/genomes/GenomesGroup.cgi?opt=phage&taxid=542837 here]<ref name=NCBI>{{cite web|last1=NCBI|title=Sp6linkevirus Complete Genomes|url=https://www.ncbi.nlm.nih.gov/genomes/GenomesGroup.cgi?opt=phage&taxid=542837|access-date=17 February 2015}}</ref>

==Life cycle==
Viral replication is cytoplasmic. The virus attaches to the host cell using its tail fibers, and ejects the viral DNA into the host periplasm. Once the viral genes have been replicated, new virions are assembled in the cell cytoplasm. Mature virions are released via lysis. Transmission route is passive diffusion.<ref name=ViralZone />

==History==
According to [[Organization:International Committee on Taxonomy of Viruses|ICTV]]'s 2009 report, the genus ''SP6likevirus'' was first accepted under the name ''SP6-like viruses'' in the family ''[[Biology:Podoviridae|Podoviridae]]'', sub-family ''Autographivirinae''. The genus name was changed to ''Sp6likevirus'' in 2012. It was moved into the subfamily ''[[Biology:Peduovirinae|Peduovirinae]]'' upon its inception in 2010–11. The following year (2012), the genus was renamed to ''P2likevirus''. These reports are available through ICTV here: [http://ictvonline.org/proposals/2007.115-9B.v2.SP6-like%20genus.pdf 2009], [http://ictvonline.org/proposals/2011.010aB.A.v2.Caudovirales_genus-ren.pdf 2012].
<ref name=ICTV>{{cite web|last1=ICTV|title=Virus Taxonomy: 2013 Release|url=http://ictvonline.org/virusTaxonomy.asp|access-date=17 February 2015}}</ref> The genus was later renamed to '''''Zindervirus''''' in the newly established family ''[[Biology:Autographiviridae|Autographiviridae]]''.
