Strangles (Streptococcus equi subsp. equi)

Veterinary care required

This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.

Priority · vet & management

On suspicion, isolate affected horses strictly, lock down the whole herd and involve the vet; diagnosis and pathogen detection (swab/PCR, possibly guttural pouch exam) and tracing long-term shedders are central. Hygiene, quarantine and herd management come clearly before any complementary feeds.

Possible causes

• · Streptococcus equi subsp. equi
• · direct contact with diseased or shedding horses
• · indirectly via drinkers, grooming kit, hands, clothing and equipment
• · silent persistent shedders (guttural pouch empyema) as a source of infection

Supportive compounds · supplementary feed, not medication

Prevention

Strict quarantine of newly stabled horses or those returning from competitions (rule of thumb approx. 2-3 weeks with temperature taking), individual equipment per horse, consistent cleaning/disinfection and clearing of persistent shedders before integration into the herd lower the outbreak risk.

Equiterna's take

Equiterna uses strangles as a textbook example of yard hygiene and quarantine. Contrary to what is often assumed, strangles is currently neither notifiable nor reportable at federal level in Germany — responsible owners nevertheless inform the yard and vet immediately; clarify regional requirements and the status in Austria with vet/authority if in doubt.
