New names of bacterial phyla![]() The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota. Published 2023-03-01. Read more... |
The taxonomy of chlamydias Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila.
