Pasteurella haemolytica antigens associated with resistance to pneumonic pasteurellosis.
Antigens associated with whole Pasteurella haemolytica biotype A serotype 1, a capsular carbohydrate-protein extract of the organism, and P. haemolytica leukotoxin were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Antigens of the electrophoresed preparations were detected by Western blotting (immunoblotting) with sera from cattle which were either nonvaccinated or vac...
متن کاملAntibiotic sensitivity of Pasteurella haemolytica isolated by means of a fibreoptic endoscope from cases of pneumonic pasteurellosis in cattle.
Bacterial isolations from tracheal and bronchial washes obtained with the aid of a fibreoptic endoscope were carried out over a 7 month period in a feedlot on calves suffering from acute pneumonic pasteurellosis. Pasteurella haemolytica and Pseudomonas aeruginosa represented the majority of isolates. Antibiotic sensitivities of the Pasteurella isolates are reported on.
متن کاملEfficacy of recombinant leukotoxin in protection against pneumonic challenge with live Pasteurella haemolytica A1.
The recombinant leukotoxin (rLKT) of the bacterium Pasteurella haemolytica A1 was examined for its ability to protect cattle from experimental challenge with logarithmic-phase P. haemolytica. Six different vaccines were utilized in the experiment: P. haemolytica culture supernatant, P. haemolytica culture supernatant enriched with rLKT, rLKT alone, P. haemolytica culture supernatant enriched wi...

متن کاملInability of passively acquired antibody to protect lambs against experimental pasteurellosis.
An experimental model of pneumonic pasteurellosis in sheep was used to investigate the role of serum antibody in resistance to this disease. Lambs which had been vaccinated with a sodium salicylate extract of Pasteurella haemolytica type A1 were protected against challenge with PI3 virus followed by P. haemolytica type A1 7 days later. The majority of untreated lambs and lambs which had receive...
