Todos tienen en comun las caracteristicas siguientes. Proteus mirabilis urinary tract infection and bacteremia. These infections may be accompanied by urolithiasis. Although other ureasepositive bacterial species are associated with catheter associated uti, only p.
Over time the stones may grow large enough to cause obstruction and renal failure. Mahadi hassan mahmoud bsc, msc, mibms microbiology 2. P mirabilis and p vulgaris account for most clinical. Microscopical morphology colony morphology diagnostic methods of proteus spp. They are opportunistic pathogens, commonly responsible for urinary and septic infections, often nosocomial. The bacteria can be found throughout the kidney and bladder stones, and can reinitiate infection after antibiotic treatment. Proteus mirabilis is a member of the enterobacteriaceae family and is a highly motile bacterium. Proteus bacilli are widely distributed in nature as saprophytes, being found in decomposing animal matter, sewage, manure soil, the mammalian intestine, and human and animal feces. Currently, the genus proteus consists of five species. Proteus mirabilis is wellknown in clinical laboratories and microbiology survey courses as the species that swarms across agar surfaces, overtaking any other species present in the process.
Urease production and robust swarming motility are the two hallmarks of this organism. Proteus vulgaris especialidades medicas medicina clinica. However, when transferred onto solid media these short rods change into elongated 2080 m in length, hyperflagellated. Proteus can also cause wound infections, septicemia, and pneumonias, mostly in hospitalized patients. Proteus are dimorphic bacteria, which in liquid media are motile, peritrichously flagellated short rods 1. This species can be identified as a gramnegative rod that is motile, ureasepositive, lactose. Proteus bacteria inhabit the environment and are also present in the intestines of humans and animals. Proteus is a ureaseforming bacterium and may be associated with urinary tract infections. Proteus mirabilis, a gramnegative rodshaped bacterium most noted for its swarming motility and urease activity, frequently causes catheterassociated urinary tract infections cautis that are often polymicrobial. The genus is currently composed of proteus mirabilis, proteus vulgaris, proteus penneri, proteus hauseri, proteus terrae, and proteus cibarius. Sharq elneil collegeschool of medical laboratory sciences department of microbiologymedical bacteriology course proteeae u. Currently, the genus is divided into proteus mirabilis, proteus vulgaris, proteus penneri, proteus hauseri, and three unnamed genomospecies 4, 5, and 6 and consists of 80 oantigenic serogroups. Proteus mirabilis y proteus vulgaris y comparte con ellos. The first isolates were reported and characterized by hauser in the late 19th century.
