Hemagglutination, autoagglutination and pathogenicity of Moraxella bovis strains.
Three isolates of Moraxella bovis, recovered from cattle with signs of infectious bovine keratoconjunctivitis, were tested for autoagglutinating activity, hemagglutinating activity and pathogenicity in young calves. Only the autoagglutinating and hemagglutinating isolates were pathogenic in calves. Treatment of the pathogenic isolates with magnesium chloride eliminated their pathogenic effects.
