Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: a curved rod. |
Species epithet: from Switzerland (where it was first isolated.
|Significance:||[Of minor importance]|
|Type Strain:||ATCC 51209= CCUG 30682 = NCTC 12470.|
|Macromorphology (smell):||Translucent and flat colonies, which are pinpoint to 0.5 mm in diameter on blood agar after 48 h.|
|Micromorphology:||Curved (seagull wing shaped) or spiral shaped small motile rods (0.2 x 1.5-3 µm) with two bipolar flagella. The motility is darting and rapid.|
|Gram +/Gram -:||G -|
|Other Enzymes:||Hippuricase - (hippurate -), urease -.|
|Biochemical Tests:||Hydrogen sulfide (H2S) -|
|Fermentation of carbohydrates:||Campylobacter spp. can neither ferment nor oxidize carbohydrates.|
|Reservoir:||Domestic cats, but also dogs.|
|16S rRNA Seq.:|
||About 40 species have been described within in the genus Campylobacter and some of these are further divided into subspecies. This genus is closely related to the following genera: Sulfurospirillum, Arcobacter and Helicobacter. C. helveticus is closely related to C. upsaliensis and C. avium.|
|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...
|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...
