How is Streptococcus equi treated?
Penicillin has long been the antibiotic of choice for treating infections with Streptococcus equi. The organism may also be sensitive to ceftiofur, tetracyclines, chloramphenicol, and trimethoprim-sulfa, although culture and sensitivity testing are recommended if one of these drugs is going to be used.
Is the strangles vaccine effective?
Strangles vaccines are considered “risk-based” vaccines. Vaccination is an effective method of disease control in individuals and in populations, however, vaccination in the face of an outbreak should be carefully considered, as there is significantly increased risk of adverse reactions in exposed horses.
Can you vaccinate for strangles?
There are currently two strangles vaccines available, a killed, “m-protein extract” which is given in the muscle, and a modified live vaccine that’s given intranasally. The intranasal vaccine is more effective and probably safer with regard to risk of purpura.
Should I vaccinate my horse for Rabies?

What causes Streptococcus equi?
Streptococcus equi causes the disease known as “strangles” in horses. It affects primarily younger horses but may affect older horses that are immunologically naive. S. equi infection is transmitted by direct contact or via fomites such as water troughs, feed bunks, pastures, and stalls.
Can a horse still get strangles if vaccinated?
The horse won’t get strangles, but the abscess will probably have to be drained in order to heal. Though this complication is also super rare, we usually recommend that horses receive strangles vaccines at a separate visit from their other vaccinations.
What disinfectant kills Streptococcus equi?
Kill the bacteria easily by heat and disinfectants such as an iodine-based disinfectant, chlorhexidine, or hot steam spray. Eliminating its spread will require steps such as: Cleaning and disinfecting water buckets and feed containers daily.
Can humans get Streptococcus equi?
It rarely infects humans and, in most cases, can be traced to an animal source (5–7). It has been associated with consumption of unpasteurized cow and goat milk products, as well as with close contacts with horses (5,8,9). A few cases were also linked to pork consumption (10).
What does Streptococcus equi cause?
Streptococcus equi is the etiologic agent for the upper respiratory disease commonly referred to as strangles. Less commonly, the bacteria may affect lymph nodes in the thorax and/or abdomen, causing a syndrome known as Metastatic strangles.
What vaccines do horses really need?
The AAEP considers the “core vaccines” which all horses should have regardless of their age or use to be Rabies vaccine, Encephalitis/Tetanus vaccine, and West Nile Virus vaccine. Many horses, based on their age and use, should also be vaccinated for the respiratory diseases- Influenza, Rhinopneumonitis, and Strangles.
Is Streptococcus equi zoonotic?
Streptococcus equi subspecies zooepidemicus (S. zooepidemicus) is a zoonotic pathogen for persons in contact with horses.
What is in a 4 way horse vaccine?
Typically, a “4-way”(EEE/WEE, Tetanus, Influenza) vaccine is administered to pasture horses and foals. A “5-way” (EEE/WEE, Tetanus, Influenza, and Rhino) vaccine is administered to 4-H, exhibition, and breeding or boarding barn horses. Depending on the risk, these vaccines may be repeated in 6-month intervals.
