Revision as of 12:36, 20 August 2008
- Haemolytic streptococci of Lancefield group C are common inhabitants of the equine nasopharynx
- Streptococcus zooepidemicus and S. equisimilis are usually non-pathogenic
- S. equi is more pathogenic and is the cause of strangles with rhinitis, pharyngitis, lymphadenitis, myositis
- S. equi may be involved in cutaneous lesions
- S. zooepidemicus can cause similar signs to strangles in horses, may accompany COPD
- May cause sinusitis in horses
- Can cause vascular fragility, leading to haemorrhagic disease.
- Secondary invadors after Equine influenza
- S. suis in pneumonia of pigs
- In pyothorax
- In osteomyelitis
- In infectious arthritis of sheep, arthritis in calves, arthritis in horses and arthritis in pigs
- In horses sometimes purpura haemorrhagica follows, especially during recovery from strangles
- In catarrhal stomatitis
- In deep pyoderma and subcutaneous abscesses
