|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|
|New families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
