|16S rRNA Seq.:|
||About 25 species have been described within in the genus Campylobacter and some of these are further divided into subspecies. This genus is closely related to the following genera: Sulfurospirillum, Arcobacter and Helicobacter. C. hyointestinalis is closely related to C. fetus and C. coli.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
