Veterinary bacteriology: information about important bacteria
|Categories:||In the normal flora; primarily of interest in human medicin|
|Etymology:||Genus name: club-shaped bakterium (bacterium means small rod).|
Species epithet: confusing (beacase this bacterium may well be confused with other bacteria within this genus).
|Significance:||C. confusum has been detected in unpasteurized milk, but is probably not pathogenic to animals.
[Of minor importance]
|Type Strain:||DMMZ 2439 = CCUG 38267|
||The colonies are small (1-2 mm in diameter) whitish and glistening.|
|Micromorphology:||Club-shaped rods, which appear singly, in pairs or in small clusters.|
|Gram +/Gram -:|
|Metabolism:||Facultatively anaerobic, but the growth is weak under anaerobic conditions.|
|Other Enzymes:||Esculinase -, urease -|
|Fermentation of carbohydrates:||
Can also ferment ribose and fructose under acid production.
|Disease:||May cause infection in humans, but it is uncommon.
|16S rRNA Seq.:|
|Taxonomy/phylogeny:||176 species and 13 subspecies are described within the genus Corynebacterium. However, not all names have been approved yet and some species have been affiliated to another genus. The genus Corynebacterium is closely related to the genera Mycobacterium, Nocardia, Rhodococcus and Crossiella.|
|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...
