- 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
