|Virulence Factors:||G. anatis has a large RTX-like toxin (GtxA), which induces a strong leukotoxic effect on avian macrophages. Furthermore, this bacterium also has a capsule and fimbriae.|
|16S rRNA Seq.:|
||Four species have been described within genus Gallibacterium, which are relatively close to members of the genus Avibacterium.|
|Comment:||There are two biovars: anatis and haemolytica.|
|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...
