Comparative virulence of some English strains of Haemophilus pleuropneumoniae serotypes 2 and 3 in the pig. 1987

S R Brandreth, and I M Smith

Between 10(7.5) and 10(8.1) viable organisms of four English and one Danish strain of Haemophilus pleuropneumoniae serotype 2 and five English strains of serotype 3 were inoculated intranasally into groups of conventional pigs. Among the English isolates of both serotypes there were virulent and non-virulent strains. Four of the serotype 2 strains, including the Danish strain, and two of the serotype 3 strains produced varying degrees of pulmonary consolidation with abscess formation and pleurisy in at least three of the five pigs in the individual groups. H pleuropneumoniae was isolated from the pulmonary lesions in all save one instance, frequently from the tonsil but less frequently from other parts of the respiratory tract. Purulent arthritis and tenosynovitis developed in one animal infected with serotype 3. Apart from the latter pig no clinical signs of illness were detected except for febrile reactions which reflected the prevalence of the thoracic lesions in the various groups. A humoral antibody response was detected by indirect immunofluorescence in two-thirds of the pigs which developed lesions but in fewer by complement fixation.
