P. mirabilis (most common, both community-acquired and nosocomial) P. vulgaris (nosocomial) urease-positive, oxidase-negative, and non-lactose fermenting gram-negative bacillus; causes urinary tract infections (UTI) Epidemiology incidence very common; demographics women > men; risk factors urinary catheter; urinary tract obstruction bacteria were first described in 1885 by Gustav Hauser, who had revealed their feature of intensive swarming growth. Washington, DC 20036 Proteus organisms are easily recovered through routine laboratory cultures. Swarming appears macroscopically as concentric rings of growth emanating from a single colony or inoculum. Inhibition ofGrowthand SwarmingofProteus mirabilis and Proteus vulgaris byTriclosan BURTOND. Swarming motility by the urinary tract pathogen Proteus mirabilis has been a long-studied but little understood phenomenon. TEDx Talks Recommended for you vulgaris and is one of the leading pathogens of the human urinary tract. Swarming is a hallmark of Proteus mirabilis, whether common gram-negative bacilli affect the swarming of P. mirabilis is still unclear. With this model, promethazine, 7-hydroxy-chlorpromazine, imipramine, 7,8-dioxochlorpromazine and acridine orange were shown to exert significant motility and swarming inhibitory action onProteus vulgaris strains at subinhibitory concentrations. Sodium azide, barbitone, and sulfonamide also inhibit Proteus swarming (1). Summary.
