Veterinary bacteriology: information about important bacteria
|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: a small spindle. |
Species epithet: refers to the most sensitive host, the quail.
|Significance:||Important in USA, because the mortality in quails is high (up to 100%).
[Of minor importance]
|Type Strain:||72042 = ATCC 27770 = CCUG 21927.|
|Macromorphology (smell):||C. colinum forms verey small colonies on bloodagar (pinpoint to 0.5 mm in diameter). The colonies are greyish white to colourless and most strains are α-hemolytic.|
|Micromorphology:||Motile and peritrichous rods (1 x 3-4 µm), which appear singly or in pairs. C. colinum has ovala and subterminal spores.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Eskulinase +, lecithinase -, tryptophanase - (= indol -).|
|Disease:||Enteritis (inflammation of the small intestine). In quails, the disease is simply called quail disease.
|Hosts:||Quails, turkeys, pheasants, grouse and chicken.|
|Clinical Picture:||Intestinal ulceration and sometimes liver nekrosis.|

|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...
