|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: a small spindle. |
Species epithet: blood-dissolving, hemolytic.
|Significance:||Is not important in Sweden, but in the USA and in South America.
[Of minor importance]
|Alternative Species Name(s):||Clostridium novyi typ D|
|Type Strain:||ATCC 9650 = NCTC 13022|
||Form small colonies (1-3 mm i diameter), which can easily float together to form a continuous carpet on the plate (the bacteria "swarm"). Give strong hemolysis on blood agar.|
|Micromorphology:||Large motile rods (0.6-1.6 x 1.9-17.3 µm), which have peritrichous flagella. Form oval subterminal spores, which result in swollen cells.|
|Gram +/Gram -:||G+, but it is difficult to get good result upon gram staining of old cultures.|
|Other Enzymes:||Esculinase -, lecithinase +, tryptophanase +|
|Fermentation of carbohydrates:||
|Spec. Char.:||Optimal growth temperature: 37°C.|
|Disease:||Bacillary haemoglobinuria in cattle (= redwater).
|Hosts:||Cattle and other ruminants|
|Clinical Picture:||Abdominal pain, anemia, dehydration, fever.|
|16S rRNA Seq.:|
||About 180 differens species have been descibed within genus Clostridium. C. haemolyticum is very closely related (phylogenetically) to C. botulinum group III and C. novyi.|
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
