Strangles disease

​What is strangles?

Strangles is caused by the bacterium Streptococcus equi. Clinical signs include:

• fever
• profuse nasal discharges
• abscessed lymph nodes of the head and neck

The swelling of these lymph nodes may in severe cases restrict the airway, hence the name 'strangles'.

The Animal Health Trust has produced a leaflet giving more information about strangles.

How does the disease spread?

Management practices have a significant impact on how easily the disease spreads through groups of animals. The disease is usually transmitted through close contact, sharing water, sharing tack and handlers not changing clothing and washing hands before moving between horses. 

Any new horses introduced to a group should be isolated.

What should I do if I suspect strangles?

If you suspect strangles, you should contact your private vet immediately.
