| Aquaspirillum | A genus of motile, nonsporeforming, aerobic bacteria (family Spirillaceae) containing Gram-negative, rigid, helical or helically curved cells which are 0.2 to 1.5 um in diameter. Motile cells contain fascicles of flagella at one or both poles. Some species can grow anaerobically with nitrate instead of oxygen as the terminal electron acceptor. These organisms are chemoorganotrophic, possessing a strictly respiratory metabolism. They do not ferment carbohydrates; a few species can oxidise a limited variety of carbohydrates. The habitat of these organisms is fresh water. The type species is Aquaspirillum serpens. Origin: L. Aqua, water, + spirillum, coil (05 Mar 2000) |

| aquagenic pruritus |
pruritus and other skin sensations, such as burning, lasting for 30 minutes to two hours, after contact with water, without the overt skin changes seen in aquagenic urticaria. The etiology is usually unknown, although it is sometimes seen accompanying polycythemia vera and in other cases it may be familial. A similar condition is seen in elderly women but lasts only 10 to 20 minutes and is relieved by emollients.
