Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the American bacteriologist W.H. Burkholder.|
Species epithet: false glanders (glanders is "malleus" in latin).
|Alternative Species Name(s):||Pseudomonas pseudomallei|
|Type Strain:||WRAIR 286 = ATCC 23343 = NCTC 12939.|
|Macromorphology (smell):||Cream coulored colonies with characteristic odour (like soil).|
|Micromorphology:||Small, motile rods, which have several polar flagella. This bacterium can also move inside a host cell by actin-based motility.|
|Gram +/Gram -:||G-|
|Metabolism:||Facultatively anaerobic (because it kan can utilize NO3- as final electron acceptor in the absence of oxygen).|
|Fermentation of carbohydrates:||Burkholderia spp. do not ferment carbohydrates.|
|Disease:||Melioidosis (similar to glanders), which is a zoonosis.
|Virulence Factors:||Capsule, secretion system av typ III och IV as well as a siderophore (malleobactin).|
|16S rRNA Seq.:|
||About 100 species have been described within genus Burkholderia, which is related to genus Taylorella. The two species of genus Burkholderia, which have beebn included in VetBact, are very closely related.|
|Legislation:||Burkholderia pseudomallei belongs to category B as a potential bioterrorism agent according to NIAID.|
|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...
