چکیده سابقه و هدف: مطالعات کمی در مورد فاکتورهای ویرولانس باکتری در شرایط و بیماری های مزمنی مثل سیستیک فیبروزیس انجام شده است. بنابراین خلط بیماران مبتلا سیستیک فیبروزیس که از مهر ماه 1390 تا مهرماه 1391 به بیمارستان مفید مراجعه کرده بودند در رابطه با تعیین ژن های مرتبط با سیستم ترشحی نوع 3(exot، exos، exou ) مورد بررسی قرار گرفتند. روش بررسی: در این تحقیق توصیفی، بر روی سودوموناس آئروژینوزا ...
Recombinant ExoU (rExoU) and yeast extract were used to optimize an in vitro phospholipase assay as a basis for identifying the mechanism for enzyme activation and substrate specificity. Our results support a model in which a eukaryotic protein cofactor or complex facilitates the interaction of rExoU with phospholipid substrates.
Pseudomonas aeruginosa is an opportunistic pathogen that typically infects patients with a compromised immune defense. Here, we present the improved 6.5-Mb draft genome of strain WS136, an ExoS-positive and ExoU-negative highly cytotoxic chronic wound isolate recovered from pyoderma gangrenosum of a patient who received bone marrow transplantation.
Abstract Background: Pseudomonas aeruginosalung infection is a major cause of morbidity and mortality in patients with cystic fibrosis (CF). The type III secretion system is an important and identified virulence determinant of P. aeruginosa that delivers effector proteins into targeted host cells. Three effector proteins have been described in P. aeruginosa: exoS, exoT, exoU. Unlike many studie...
background: pseudomonas aeruginosa is considered an opportunistic pathogen; several reports indicate that the organism can also cause infections in healthy hosts. four effector proteins have been described in p. aeruginosa: exou, exos, exot, and exoy. these genes that are translated into protein products related to type iii secretion systems. materials and methods: a total of 134 samples were i...
The genetic structure of a population of Pseudomonas aeruginosa, isolated from patients with keratitis, endophthalmitis, and contact lens-associated red eye, contact lens storage cases, urine, ear, blood, lungs, wounds, feces, and the environment was determined by multilocus enzyme electrophoresis. The presence and characteristics of virulence factors were determined by restriction fragment len...
