Summary: The swarming of is inhibited on a heated blood-agar medium containing 0·1 % (w/v) boric acid. This boric acid concentration does not inhibit the growth of many organisms having more exacting metabolic requirements. The medium is equally successful in controlling certain swarming strains of This inhibition of swarming is possibly due to the formation of a boron-polysaccharide complex, resinous in character, the formation of which is associated with flagellar disintegration.
