Species/Subspecies: Burkholderia pseudomallei
Categories: Zoonotic; motile
Etymology: Genus name: named after the American bacteriologist W.H. Burkholder.
Species epithet: false glanders (glanders is "malleus" in latin).
Significance:  [Important]   
Alternative Species Name(s):Pseudomonas pseudomallei
Taxonomy:
Phylum
Proteobacteria
Class
Betaproteobacteria
Order
Burkholderiales
Family
Burkholderiaceae 
Genus
Burkholderia
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).
Catalase/Oxidase:+/+
Fermentation of carbohydrates: Burkholderia spp. do not ferment carbohydrates.
Spec. Char.:
Disease:Melioidosis (similar to glanders), which is a zoonosis.
Hosts: Horse etc.
Clinical Picture:
Virulence Factors: Capsule, secretion system av typ III och IV as well as a siderophore (malleobactin).
Genome Sequence:
Acc-noStrainSize (bp)Genome
NC_006350 and NC_006351 K96243 7 247 547 2c + 0 
Chrom. I (4 074 542 bp) and Chrom. II (3 173 005 bp), respectively.

16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
DQ108392 (T) 1488 
Three rRNA genes in chrom. I and one in chrom. II.

Taxonomy/phylogeny:
   
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.

The revised taxonomy of the mollicutes

The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.
