Expression of the Escherichia coli ompW colicin S4 receptor gene is regulated by temperature and modulated by the H-NS and StpA nucleoid-associated proteins
(Wiley Blackwell Publishing, Inc, 2014-03)
The OmpW family consists of a ubiquitous group of small outer membrane (OM) β-barrel proteins of Gram-negative bacteria with proposed roles in environmental adaptation but poorly understood mechanisms of expression. We ...
Salmonella typhi Ty2 OmpC porin induces bactericidal activity on U937 monocytes
(Blackwell Publishing Asia, 1997)
The immunogenic effect of Salmonella typhi OmpC porin during typhoid fever in humans was evaluated in vitro. Peripheral blood mononuclear cells from 17 patients were challenged with outer membrane preparations from Escherichia ...
Oral delivery of Brucella spp. recombinant protein U-Omp16 abrogates the IgE-mediated milk allergy
(Landes Bioscience, 2014-05)
Food allergies are increasingly common disorders and no therapeutic strategies are yet approved. The unlipidated Omp16 (U-Omp16) is the outer membrane protein of 16 kDa from B. abortus and possesses a mucosal adjuvant ...
Alteration in the electrophoretic mobility of OmpC due to variations in the ammonium persulfate concentration in sodium dodecyl sulfate‐polyacrylamide gel electrophoresis
(1991)
Studies on Salmonella typhi and Salmonella typhimurium outer membrane proteins have shown that the relative position of OmpC porin in sodium dodecyl sulfate‐polyacrylamide gel electrophoresis undergoes an important shift ...
Perfil de porinas asociado a la impermeabilidad celular en cepas de Klebsiella pneumoniae resistentes a antimicrobianos
(Facultad de Ciencias Básicas y TecnologíasArmeniaCiencias Básicas y Tecnologías - Biología, 2009-10-14)
Las bacterias del genero Klebsiella son una causa frecuente de infecciones nosocomiales. Uno de los principales factores de virulencia son las proteínas de membrana externa. Se ha descrito previamente que Klebsiella ...
Cloverleaf test (modified Hodge test) for detecting carbapenemase production in Klebsiella pneumoniae: be aware of false positive results
(Oxford Univ Press, 2010-02-01)
The aim of this study was to evaluate the presence of carbapenemases in a Klebsiella pneumoniae collection and the performance of the modified Hodge test (MHT) to correctly identify this phenotype.Twenty-eight K. pneumoniae ...

Evaluación de la Inmunogenicidad y capacidad protectora de la porina OmpS1 de Salmonella enterica serovar Typhi
(30/06/2009)
ABSTRACT: Immunological memory has been described as the capacity of an organism to respond faster and more efficiently to an antigenic re-exposition, this is one of the main characteristics of the adaptive immune response. ...
