The virulence of strains of Haemophilus pleuropneumoniae serotype 1, 2, 3, 7 and strains of the "minor-group" and Haemophilus parasuis were compared by inoculating specific pathogen-free pigs into the lower airways with specified doses of bacteria. Haemophilus pleuropneumoniae, strain W, serotype 1, given in 1 X 10(8) colony-forming units, produced a lethal acute pleuropneumonia in four pigs.
