Strangles - A highly contagious, equine plague spreading worldwide.

Strangles is caused by the bacterial Streptococcus equi, an infection which has affected horses almost since the antiquity. The number of cases is steadily growing. The disease is similar with, tonsillitis/paratonsillitis/scarlet fever in humans, caused by Streptococcus pyogenes. In Sweden, strangles is one of few bacterial infections in horses, which must be reported to the authorities.

The infection ceases after about a month. The infection is very contagious and requires full isolation of an affected facility. Due to the highly contagious character of this disease, a rapid diagnosis combined with isolation of suspected cases is the most effective step in reducing the outbreak. Approximately 5 procent of infected horses develop life threatening complications or death.

The Swedish research company Intervacc where Nordvacc is the majority owner, is on track to develop a vaccine, Strangvac® against strangles. Strangvac® has shown good documented protective effect against a disease that has lacked an adequate vaccine protection.
