What does strangles do to a horse?
It affects horses, donkeys and ponies of all ages, breed and sex. The bacteria often infect the lymph nodes around the jaw, causing them to become swollen. In severe cases they can become so swollen that horses struggle to breathe properly, hence the name 'Strangles'.
Abstract
Antibiotic treatment of horses with strangles is reported to impair the development of immunity to subsequent exposure to Streptococcus equi ssp equi ( S. equi ). However, apart from a single clinical report, evidence‐based studies for this hypothesis are lacking.
1 INTRODUCTION
Strangles is a highly infectious upper respiratory tract disease in horses caused by the β‐hemolytic Lancefield group C bacteria, Streptococcus equi subspecies equi ( S. equi ).
2 MATERIAL AND METHODS
A strangles outbreak with 100% morbidity occurred in late April 2015 in a closed group of 43 adult Icelandic horses. Two horses were euthanized at the onset of the outbreak because of the development of clinical signs of strangles in combination with advanced age and poor dentition.
3 RESULTS
All horses were qPCR positive for S. equi on NL samples on sampling T27 (39/41 positive horses) or sampling T46 (2/2). Most of the horses (31/41; 76%) also were S. equi positive on culture at sampling T27 (Figure 1 ).
4 DISCUSSION
These results provide supportive evidence that antibiotic treatment during acute clinical strangles can impair persistence of humoral immunity against S. equi. Based on principles of immunology, these findings were not unexpected.
5 CONCLUSION
Treatment of horses with penicillin during acute clinical strangles is associated with persistence of seropositivity to S. equi. Whether this limitation in the duration of antibodies against S. equi leads to increased susceptibility to recurrence of clinical strangles after re‐exposure to an infective challenge of S. equi remains to be determined.
ACKNOWLEDGMENTS
All personnel and horse owners from the affected stable, Karin Nygren, Kamilla Ekström, and Cecilia Ekberg are thanked for their assistance during sample collection throughout the study.
How long does it take for a horse to recover from strangles?
The prognosis for full recovery of uncomplicated cases of strangles is good, but usually takes 3 to 6 weeks. Approximately 70-75% of infected horses go on to develop an immunity to S. equi that can last for at least five years.
Why do horses need antibiotics?
Antibiotics may be beneficial immediately after the onset of fever, prevent the formation of abscesses, and relieve airway obstruction, but their use is controversial because horses can have an altered post-infection immune response, which may leave them at risk for re-infection.
What is a strangle?
What is strangles? Strangles is a highly contagious disease of the equine upper respiratory tract caused by the bacterium Streptococcus equi subspecies equi (S. equi). The bacteria cross mucous membranes in the nose and mouth to infect lymph nodes where they cause abscesses that can eventually rupture.

Horses that haven’t been exposed to the bacteria in recent years are more prone to strangles. Intramuscular and intranasal vaccines are available for horses. These vaccines decrease the severity of strangles symptoms but don’t completely prevent the disease.
What happens if a horse has a swollen throat?
A few days after onset, the horse will develop painful swelling of the lymph nodes. This swelling produces abscesses that will rupture and discharge pus. More serious cases arise when horses have lymph node swelling in the throatlatch area.

Is strangles a contagious disease?
Every state/country is different and will have their own laws and regulations but strangles is highly contagious and as such is generally considered a notifiable disease. This means that you’ll need to report any cases or even suspected cases.
What is the name of the disease that causes strangles?
The upper respiratory disease commonly referred to as strangles is caused by Streptococcus equi subsp equi. Less commonly, the bacteria affect lymph nodes in the thorax and/or abdomen, causing a syndrome known as metastatic or “bastard strangles”.
Can a horse die from strangles?
Strangles is rarely fatal, and most horses will recover with supportive care. Death in the acute phase of the disease can occur as a consequence of upper airway compression from retropharyngeal or peritracheal abscess formation. Complications of strangles can result in severe disease that may lead to euthanasia. Internal abscesses can form in the lung, liver, spleen, kidney, brain, mediastinum, and/or mesentery. Culture and PCR of abscesses identified during gross necropsy is usually diagnostic. Immune-mediated complications include purpura hemorrhagica, myositis, glomerulonephritis, and myocarditis. Purpura hemorrhagica leads to petechial or ecchymotic hemorrhages on mucous membranes, sclera, and visceral surfaces such as the lung. Purpura hemorrhagica can result in subcutaneous edema most commonly involving the head, limbs and trunk. Severe edema may result in oozing from the skin surfaces and sloughing of skin in the affected areas. Rhadomyolysis and infarctive myositis are also associated with purpura hemorrhagica. Significant rhabdomyolysis with progressive atrophy has been identified in Quarter Horses.
How to test for PCR?
The exact choice of test relies on the clinical scenario, but a rough guide should be: 1 If there is an external abscess, then a swab for culture and PCR 2 If there is nasal discharge, then a pharyngeal wash for PCR 3 If there is no overt clinical disease but you are checking for carrier status, then a guttural pouch wash for PCR/culture 4 Serology can be used prior to movement to confirm no recent exposure
What is Strangles in horses?
Strangles, caused by Streptococcus equi subspecies equi ( S. equi ), is frequently seen within the equine population, affecting horses of all ages. In most cases, the clinical signs are characterised by acute onset pyrexia, pharyngitis and secondary formation of abscesses within the submandibular and retropharyngeal lymph nodes.
What is S. equi infection?
S. equi infection is normally a mild respiratory disease that has more yard implications than it does for the individual horse. Affected horses should be closely monitored to ensure they do not progress or require intensive therapy, but the mainstay of veterinary involvement includes biosecurity implantation.
How long does it take for pyrexia to occur?
Pyrexia, often exceeding 42°C (Waller, 2014), occurs 3 to 14 days after exposure to the bacteria, leading to some difficulty in assessing the epidemiological spread of the disease. Following pyrexia, patients can show lymphadenopathy leading to abscesses.
Can S. equi affect horses?
S. equi can affect any age of horse but will often be more severe in those that are young due to a lack of innate immunity (although foals can have maternally derived antibodies inferring a degree of immunity).
How long does equi shedding last?
Shedding. S. equi shedding usually begins two to three days following the onset of pyrexia and can continue for two to three weeks in most animals. This can be longer when there is persistent infection within the guttural pouch or sinus.
Can antibiotics be used as a preventative?
Antibiotics should not be used as a preventative. This will increase resistance in the bacterial populations and decrease the immune response. If antibiotics are warranted, penicillin is considered the drug of choice and there is very little evidence of emerging resistance to antibiotics.
