Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: a cloac. |
Species epithet: of a pig.
|Significance:||[Of minor importance]|
|Type Strain:||S45 = ATCC VR-1474.|
|Micromorphology:||Utanför värdcellen: infektiösa elementarkroppar (0,2-0,3 µm).
I värdcellen: icke-infektiösa retikulärkroppar (0,8-1,0 µm). C. trachomatis är orörlig.
|Gram +/Gram -:||G-, difficult to gram stain.|
|Metabolism:||Aerobic, but members of the family Chlamydiaceae have only limited resources to to synthesize their own ATP. Therefore, they can ingest ATP from the host cell.|
|16S rRNA Seq.:|
||Species within the family Chlamydiaceae were previously (1999) 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 (2015) to the genus Chlamydia. See the references below.|
|Comment:||Strictly intracellular. The cell envelope contains cystein rich proteins and only a small amount of peptidoglycans.|
|Reference(s):||No. 68, 140, 177|
|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...
