Potomac horse fever or PHF is caused by Neorickettsia risticii. Main clinical sign of PHF is acute colitis which is caused due to infection of large and small colon. This disease affects the horses usually in summer, early spring and early fall. In this article you can learn all about the Potomac horse fever and its herbal treatment by Planet Ayurveda.


PHF or Potomac horse fever is a sporadic, seasonal, severe but acute form of colitis in horses caused due to infection of Neorickettsia risticii, which is a gram negative bacteria. Usually it is reported in the areas of Canada, United States, Europe, and India. Any breed of horse may get affected, however the young horses are more prone to it.


As per Ayurvedic concepts the three doshas, i.e. Vata, Pitta and Kapha, their balance is necessary for the maintenance of health. Any imbalance in any of these doshas can cause disease. PHF is also caused due to the vitiation of the tridoshas usually the Pitta dosha is involved..

The different signs and symptoms of Potomac horse fever are

  • Initially the symptoms are mild involving anorexia and depression
  • Diarrhea which ranges from mild to severe form as the time passes
  • Abdominal discomfort
  • Sepsis
  • Dehydration
  • In female pregnant horses, abortion may occur
  • Enlarged lymph nodes
  • Enlarged spleen


N risticii is the causative agent, it is a gram negative bacteria. This organism is found in the freshwater snails, stoneflies, caddisflies, damselflies and dragonflies. The infection occurs due to the ingestion of any of these aquatic insects which carry the organism. After the infection, 10-18 days are incubation periods. This bacteria is also present in the stool of the experimentally infected horses. However the horses that are clinically ill are not contagious and can be placed with other healthy horses.


Typical clinical signs are the first base of diagnosis of the disease. Further blood and fecal samples are taken to confirm the diagnosis by the isolation of the organism. Serological testing is usually not confirmatory as many times the antibody titre is falsely high in the healthy horses as well. Also the culture of organisms is time taking and many times not available in the nearby laboratory. Hence the mostly used test is real-time PCR assay where the organism is detected within 2 hours. The PCR should be performed on both the stool as well as blood sample.


Conventional treatment of PHF includes prescription of oxytetracycline which is to be given in early phases of infection, if diagnosed. This shows results within 12 hours where all the symptoms start to improve gradually. Antimicrobial treatment should be given for 5 days only. If the infection is severe fluids and NSAIDs are to be given.


Ayurvedic treatment aims at balancing the tridosha, i.e. Vata, Pitta and Kapha by the use of herbal remedies and other Ayurvedic modes of treatment. Also there are certain dietary changes which are done as per Ayurveda during the treatment for best results.
