Bacterial world has seen to consist three major classes i.e. Eubacteria, Spirochaetae and Myxobacteria. Myxobacterium is one of the remarkable bacteria that has special distinctive property of multicellular and macroscopic features that are called fruiting bodies. Unlike other motile prokaryotes, myxobacterium does not have visible organelles of locomotion however, some of them show gliding motility. This signifies the complex life cycles of myxobacterium that come along with the diverse physiological characteristics.
FRUITING MYXOBACTERIA
TAXONOMY
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
-
Myxobacteria are heterotrophs, aerobes and gram negative rod-shaped bacteria
-
Myxobacteria were grouped together under the order myxococcales
-
Myxobacteria were then further divided into different suborder and family based on their shape of vegetative cell, myxospores and the colonies formed
-
As a whole, there are three suborders, five families, 17 genera and about 50 species of myxobacteria were known today (Dworkin, et al., 2006)

-
Later and modern studies which analyse the sequences of their 16S rRNA/DNA shown that myxobacteria are phylogenetically falls among the δ-proteobacteria division together with bdellovibrio and desulfovibrio (Yan, et al., 2003)
-
Unlike desulfovibrio, both bdellovibrio and myxobacteria are aerobes which suggest that these two evolve aerobic properties from their anaerobic sulphur- sulphate-reducing bacteria (Shimkets & Woese, 1992).
