Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the German microbiologist Norbert Weiss, who has worked with taxonomy of lactic acid bacteria.|
Species epithet: refers to Korea, where the bacterium was first isolated.

|16S rRNA Seq.:|
|Comment:||W. koreensis is the dominating bacterial species during fermentation at low temperature. This bacterium also contributes flavour of the product.|
|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. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
