Veterinary bacteriology: information about important bacteria
|Categories:||Zoonotic; motile; primarily of interest in human medicin|
|Etymology:||Genus name: named after the Peruvian scientist Alberto L. Barton (1870-1950), who described this species in 1909.|
Species epithet: named after Diane M. Hensel, who isolated many of the original strains.
|Significance:||[Of minor importance]|
|Alternative Species Name(s):||Rochalimaea henselae|
|Type Strain:||Houston-1 = G5436 = ATCC 49882 = CCUG 30454|
||Heterogenic colonies, small regular to irregular larger forms (0.2-1 mm in diameter). No hemolysis on blood agar.|
|Micromorphology:||Small (0.5-0.6 x 1.0 µm), motile (twitching), slightly bent rods, but lacks flagella.|
|Gram +/Gram -:||G- (weakly stained)|
|Other Enzymes:||Tryptophanase -, urease -|
|Biochemical Tests:||Voges-Proskauer -|
|Fermentation of carbohydrates:||Bartonella spp. do not produce acid by fermentation of carbohydrates.|
|Spec. Char.:||Optimal temperature: 35-37°C. Very fastidious in culture.|
|Vector:||Cat flea (Ctenocephalides felis)|
|Disease:||Cat scratch disease in humans
|16S rRNA Seq.:|
||More than 30 species have been described within genus Bartonella, which is relatively closely related to genus Brucella.|
|Comment:||Zoonotic, vector-borne (lice and possibly ticks)|
|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...
