[mod.L. (W. Migula 1897, in Arbeiten aus dem Bakteriol. Inst. der Technischen Hochschule zu Karlsruhe I. 237), f. pseudo- + Gr. µονάς unit.]
A bacterium of the genus Pseudomonas, which comprises aerobic Gram-negative species that occur chiefly in soil and water, are generally rod-shaped, frequently produce soluble pigments, and include many plant pathogens but few animal pathogens. Freq. attrib.
1917Jrnl. Bacteriol. II. 174 The vibrios are..closely akin to the fluorescent (or pseudomonas) bacteria. 1950C. J. Witton Microbiol. xxvi. 366 Pseudomonas intestinal infections of infants and pseudomonas bronchopneumonias have also been reported. 1961Lancet 22 July 179 Recurrence of Pseudomonas infection while on i.m. polymixin after sterile culture for 16 days. 1966New Scientist 21 July 150/1 Currently, research is centred on fish bacteria which cause disease, such as vibrio and pseudomonas. 1977Time 24 Jan. 55/3 These have sharply reduced infection from pseudomonas bacteria, which once killed nearly a third of all burn victims.
So pseudoˈmonad, a bacterium of the genus Pseudomonas, or one of the family Pseudomonadaceæ that includes it, or one of the order Pseudomonadales that includes the family.
1921R. E. Buchanan Agric. & Industr. Bacteriol. xxxiv. 407 The organism is a typical yellow pseudomonad in morphology, culture and physiology. 1958Pelczar & Reid Microbiol. xii. 125/1 Many Pseudomonas species, or ‘pseudomonads’, produce water-soluble pigments. 1966McGraw-Hill Encycl. Sci. & Technol. XI. 63/1 Pseudomonads, as members of the genus are familiarly known. Ibid. 64/1 Aeromonas is composed of pseudomonads which physiologically resemble bacteria of the genus Aerobacter. 1973J. Levy et al. Introd. Microbiol. xiii. 334 Order Pseudomonadales... The pseudomonads are ubiquitous in nature, are largely free-living.., and have achieved economic importance in that they are the most common cause of food spoilage. 1975Nature 24 Apr. 671/1 The most striking metabolic capability of pseudomonad organisms is their versatile utilisation of organic compounds as sole sources of carbon, nitrogen and energy. |
