Reactive arthritis (ReA) is a sterile arthritis triggered by distal mucosal infection, which suggests a contribution from bacterial products. The pathogenesis of ReA is unclear. There are no international standards for the serological methods used to confirm ReA. In the present work, we analyzed the predominant bacterial component that triggered an immune response in a 24-year-old woman with ac...
We analyzed the possible causes of imipenem (IPM) resistance in multidrug-resistant isolates of Acinetobacter baumannii. Comparison of the outer membrane protein (OMP) profiles of two genomically related strains (Ab288 [IPM sensitive] and Ab242 [IPM resistant]) indicated the conspicuous loss of a 29-kDa polypeptide in the Ab242 strain. No carbapenemase activity was detected in any of these stra...
Brucella melitensis is an organism of paramount zoonotic importance. The 28 kDa outer membrane protein (OMP) is one of the immunodominant antigens of B. melitensis. The gene encoding 28 kDa OMP (omp28) has been amplified from B. melitensis Rev. 1 strain. A PCR product of 753 bp, encoding complete omp28 gene of B. melitensis, was obtained. The gene was further cloned and sequenced. The nucleotid...
fhuA of Actinobacillus pleuropneumoniae encodes a ferrichrome receptor but is not regulated by iron.
The swine pathogen Actinobacillus pleuropneumoniae possesses a 75-kDa outer membrane protein (OMP), FhuA, the receptor for ferrichrome, a hydroxamate-type siderophore. Polyclonal serum to FhuA reacted with OMP preparations from 12 serotypes of A. pleuropneumoniae under conditions of iron repletion and restriction. Reverse transcription-PCR confirmed that A. pleuropneumoniae fhuA expression is n...
To survive in the presence of a wide range of toxic compounds, gram-negative bacteria expel such compounds via tripartite efflux pumps that span both the inner and outer membranes. The Salmonella-specific MdsAB pump consists of MdsB, a resistance-nodulation-division (RND)-type inner membrane transporter (IMT) that requires the membrane fusion protein (MFP) MdsA, and an outer membrane protein (O...
Helicobacter pylori is a gram-negative bacterial pathogen that chronically inhabits the human stomach. To survive and maintain advantage, it has evolved unique host-pathogen interactions mediated by Helicobacter-specific proteins in the bacterial outer membrane. These outer membrane proteins (OMPs) are anchored to the cell surface via a C-terminal β-barrel domain, which requires their assembly ...
اشریشیا کلی، یکیازمهم ترین اعضای خانواده انتروباکتریاسهو جزء فلور طبیعی روده پستانداران و پرندگان محسوب می شود. برخی از سویه های این باکتری قادرند که در انسان و حیوانات، عفونت های گوناگون گوارشی و غیرگوارشی مختلفی ایجاد نمایند.طیف وسیعی از عفونت های غیرگوارشی در انسان و حیوانات به وسیله سویه های اشریشیا کلی خارج روده ای (expec) ایجاد می شوند. از آن جمله می-توان به سویه های اشریشیا کلی پاتوژنیک ...
Haemorrhagic septicemia (HS) caused by Pasteurella multocida (serotype B: 2) is an important disease of cattle and buffaloes in Asian sub-continent. Presently available vaccines for HS have their own limitations. Efforts have been made to develop better vaccine targeting outer membrane proteins and few of them have shown potential . Omp 87 protein has shown a protective potential against fowl c...
The attachment of Pseudomonas aeruginosa to human respiratory mucus represents an important step in the development of lung infection, especially in cases of cystic fibrosis. For this purpose, microtiter plate adhesion assays have been developed and have suggested that nonpilus adhesins of P. aeruginosa are the most important ones for binding to human respiratory mucins. In order to characteriz...
A B-cell line producing a human monoclonal antibody (HuMAb) against a recombinant 40-kDa outer membrane protein (OMP) of Porphyromonas gingivalis was constructed by in vivo immunization of a severe combined immunodeficiency C.B.-17/Icr mouse, which had been injected with human peripheral blood lymphocytes, with recombinant 40-kDa OMP and subsequent Epstein-Barr virus immortalization of B cells ...
