Kuttervirus
genus of bacteriophages
Kuttervirus is a genus of bacteriophages in the family Ackermannviridae. The genus contains 40 species.
Characterization
The heads of these phages are icosahedral in nature. Their tails are composed of a collared neck (similar in structure to that of a T4 phage), “a sheath surrounding a tail tube or core, a thin base plate, and an adsorption structure” Notably, a series of unique protrusions can be found stemming from the base plate of these organisms. 3 to 4 thick, rounded prongs (located at the bottom of the base plate) and an equal number of thinner, star-like protrusions (attached to the sides of the baseplate via a stalk) have been observed in members of the genus.
Members of the genus are similar in terms of genomics. All species in the genus showed above a 75% commonality in protein composition. While “the gene order is strongly conserved in all seven phages…various functional regions are randomly distributed throughout the genome…”. Functional clustering, as observed in other genera of phages, is uniquely absent from Kuttervirus, and proves to be a defining quality of the genus.
Due to the diversity in tail-spike filaments, researchers have suggested that these phages may be capable of infecting a wider range of hosts.
“Kuttervirus” enters the record as genus of bacteriophages. Crown Archives preserves that source wording while asking what Kuttervirus, genus and bacteriophages can confirm, complicate or overturn.
Why this record matters
“Kuttervirus” is worth following because a concise public description often conceals a longer documentary argument. Here, Kuttervirus, genus and bacteriophages provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 30, 2026. The linked authority identifier is Q18395606. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
