Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: a helix shaped rod. |
Species epithet: named after the German scientist Hugo Salomon, who was one of the first workers to describe three spiral shaped, but morphologically distinct bacteria from the canine gastric mucosa.
|Significance:||[Of minor importance]|
|Type Strain:||Inkinen = CCUG 37845|
|Micromorphology:||Loosely helical or curved rods(0.8-1.2 x 5-7 µm) that have 10-23 bipolar flagella.|
|Gram +/Gram -:||G-|
|Other Enzymes:||Urease +|
|Fermentation of carbohydrates:||Helicobacter spp. can neither ferment nor oxidize carbohydrates. Exception: H. pylori, which can oxidize glucose to acetate.|
|Disease:||H. salomonis has been isolated from the gastric mucosa of healthy dogs. Pathogenicity not known.
|16S rRNA Seq.:|
||About 35 species have been described within the genus Helicobacter, and this genus is most closely related to Campylobacter, Arcobacter and Sulfurospirillum. H. salomonis is closely related to H. felis and H. bizzozeroni.|
|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...
