|16S rRNA Seq.:|
||About 175 species have been described within genus Mycobacterium and this genus is closely related to Rhodococcus, Nocardia and Corynebacterium. M. tuberculosis, M. bovis and M. caprae are very closely related to each other and have sometimes been regarded as subspecies of M. tuberculosis.
It is common to use the term Mycobacterium tuberculosis complex (MTC or MTBC) or Mycobacterium tuberculosis clade for the following very closely related species: M. africanum, M. bovis, M. canetti, M. caprae and M. tuberculosis and some other species, which are less important.

|New families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
