Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after K. Glässer who first described the disease in pigs. |
Species epithet: (Haemophilus) suis-liknande.
|Alternative Species Name(s):||Haemophilus parasuis|
|Type Strain:||ATCC 19417 = CCUG 3712 = NCTC 4557|
|Micromorphology:||Small non-motile rods|
|Gram +/Gram -:||G-|
|Other Enzymes:||Esculinase -, tryptophanase -, urease -.|
|Biochemical Tests:||Hydrogen sulphide (H2S) V.|
|Fermentation of carbohydrates:||
Other carbohydrates: Adonitol -, dulcitol -, D-galactose +, inositol V, melezitose -, melibiose -, sorbose -, xylitol -.
|16S rRNA Seq.:|
||About 2 species have been described within genus Glaesserella, but the relationship between members within the closely related genera Actinobacillus, Glaesserella, Haemophilus, Mannheimia and Pasteurella is very uncertain since only few of these genera forms monophyletic clusters.
Note that the name of this bacterium is still Haemophilus parasuis in the phylogenetic tree.
|Comment:||The V-factor is required for growth, but not the X-factor.|
|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...
