Gliding Motility

Also found in: Encyclopedia, Wikipedia.

A twitching and translocating pattern of movement, typical of Capnocytophaga spp, in which the yellowish colonies display finger-like projections, that appear to glide over the primary isolation media—e.g., heart infusion agar; these gram-negative fusiform bacilli are indigenous to the oral cavity, are implicated in periodontal and oral infections and lack flagella

The identification of the isolated Flavobacterium strain was checked on the basis of the characteristic yellow-green colonies, with rhizoid edges that contained Gram negative rods exhibiting gliding motility (Shamsudin and Plumb, 1996).

Gliding motility was checked under a microscope (magnification, x 100) by using a hanging drop preparation of a 48 hours liquid medium culture.

The four strains isolated in this study were similar in size, shape and the gliding motility of bacteria.
