Comparison of outer membrane protein and biochemical profiles of Haemophilus aegyptius and Haemophilus influenzae biotype III.
Haemophilus aegyptius and Haemophilus influenzae biotype III are morphologically and biochemically similar; however, their outer membrane protein (Sarkosyl insoluble) profiles are distinct. Of 18 strains of H. aegyptius examined, 15 had a type 1 protein profile, and 3 had a type 2 profile, whereas the 5 strains of H. influenzae biotype III examined had three other protein profile types. All Hae...
متن کاملAntibody response of swine to outer membrane components of Haemophilus pleuropneumoniae during infection.
Sera from pigs infected with Haemophilus (Actinobacillus) pleuropneumoniae were tested for antibodies to outer membrane proteins (OMPs) of the organism by immunoblotting. Convalescent sera were produced in naturally born, colostrum-fed pigs and in cesarean-derived, colostrum-deprived pigs given H. pleuropneumoniae serotype 5 intranasally twice at 5-week intervals. Sera, collected at weekly inte...
متن کاملEffect of iron restriction on the outer membrane proteins of Actinobacillus (Haemophilus) pleuropneumoniae.
The outer membrane protein profile of Actinobacillus (Haemophilus) pleuropneumoniae grown under iron-restricted and iron-replete conditions was studied by polyacrylamide gel electrophoresis and immunoblotting. A virulent serotype 1 isolate synthesized a novel protein with an apparent molecular weight of 105,000 (105K) and increased the synthesis of a 76K protein under iron-restricted conditions...
متن کاملIdentification and characterization of a novel stress-responsive outer membrane protein Lip40 from Actinobacillus pleuropneumoniae
BACKGROUND Actinobacillus pleuropneumoniae, a Gram-negative bacterium, is the causative agent of porcine pleuropneumonia, a highly contagious and often fatal disease. Because current vaccines confer limited protection against A. pleuropneumoniae infection, the development of more effective vaccines is urgently required. The identification of immunogenic and protective antigens, such as an outer...
متن کاملMembrane Protein of Haemophilus somnus
We purified the major outer membrane protein (MOMP), which is the most abundant OMP (with an apparent molecular mass of 40 kDa), from Haemophilus somnus strain 8025. The method involves solubilization of the MOMP with Zwittergent 3-14 and further purification accomplished by ion-exchange and molecular-sieve chromatographies. The amino-terminal sequence of the MOMP showed considerable similarity...
