|Hosts:||Dog? cat? and humans?|
|Diagnostics:||Direct culture on selective media or culture after selective enrichment. Confirmation by MALDI-TOF, PCR or other molecular methods. Biochemical tests can also be used for confirmation.|
|16S rRNA Seq.:|
||About 40 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 Helcobacter. C. upsaliensis is closely related to C. helveticus and C. avium.|
In Sweden, human campylobacteriosis is notifiable to the Public Health Agency of Sweden.
|The revised taxonomy of the mollicutes (mycoplasmas)|
About 2 years ago, the taxonomy of mycoplasmas was revised at VetBact, because a research group had proposed that 5 new genera should be included together with the genus Mycoplasma. This also had consequences for higher taxa within the phylum, which was then called Tenericutes. Now another group of researchers has suggested that the new names should be rejected.Published 2023-10-03. Read more...
