|Etymology:||Genus name: named after the Swiss bacteriologist Jacques Nicolet, who has studied the family Pasteurellaceae in his research. |
Species epithet: semolina (the colonies look like semolinas).
|Significance:||Is regularly isolated from Swedish horses with respiratory problems, but it does not necessarily prove that N. semolina is the causative agent
|Type Strain:||CCUG 43639.|
||Small white colonies (0.5-2 mm in diameter), which are similar to semolinas. The colonies can be moved on the agar surface with a plastic loop without losing the shape. Give no hemolysis at blood agar.|
|Micromorphology:||Short, non-motile and pleomorphic rods.|
|Gram +/Gram -:||G-|
|Other Enzymes:||Eskulinase (= beta-glucosidase) (-), ornithine decarboxylase -, tryptophanase (indole) -, urease +|
|Biochemical Tests:||Citrate -, hydrogen sulphide -.|
|Fermentation of carbohydrates:||
|16S rRNA Seq.:|
||There is only one species described within the genus Nicoletella. which is relatively close to Histophilus somni, which also is a single species within its genus.|
|Reference(s):||No. 1, 51|
|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...
