  • Inhabits nasopharynx of normal swine
  • Serotype B causes Glasser's disease in pigs
  • Glasser's disease
    • Septicaemia
    • Acute inflammation affecting pleua, peritoneum, mediastinum, pericardium, joints and meninges
    • Causes a polyserositis - pericarditis, peritonitis, pleurisy and meningitis - in pigs 3-10 weeks old
    • Also causes suppurative bronchopneumonia, pleuritis, polyarthritis (also H. suis)
    • Expressed lesions vary between animals - meningitis is most consistent, arthritis in 20% of cases
    • Fever, general malaise, repsiratory and abdominal signs, lameness, paralysis or convulsions
    • Sporadic outbreaks in the UK
    • Morbidity and mortality often low due to widespread acquired resistance
    • Mortality up to 50% in some outbreaks e.g. specific pathogen-free herds
    • Can be fatal in 2-5 days
    • Chronic arthritis, meningitis and intestinal obstruction due to adhesions in some surviving pigs
    • Due to transport, environmental stresses, dietary and managemental factors
  • Fibrinous pneumonia secondary to enzootic pneumonia or virus infection e.g. swine influenza


    • Cause Glasser's disease
    • Fibrinous polyserositis, polyarhritis, meningitis
