Equine Herpesvirus (EHV)

Equine Herpesvirus (EHV, or rhinopneumonitis) type 1 (EHV-1) and type 4 (EHV-4) infect the respiratory tract, causing disease that ranges from minor to severe.

Equine Herpesvirus Myeloencephalopathy (EHM)

Equine influenza virus (EIV) is one of the most common and contagious infectious upper respiratory diseases in horses.

Equine Protozoal Myeloencephalitis (EPM)

Equine Protozoal Myeloencephalitis (EPM) is a progressive disease of the central nervous system (brain and spinal cord) in horses. It is most commonly caused by the protozoal organism Sarcocystis neurona.

Equine Rhinopneumonitis (EHV-1 Abortion)

A clinical syndrome or abortion storms in horses due to EHV-1.

Equine Rhinopneumonitis (EHV-1 and EHV-4)

Typical signs of equine herpesvirus respiratory disease include fever, congestion, cough, loss of appetite, nasal and eye discharges, fatigue, and swollen lymph nodes.

Escherichia coli

A mare’s reproductive cycle follows the rhythms of nature. With estrus (fertility and sexual receptivity) occurring during spring and summer when the daylight hours are long.

Large strongyles

There are three primary species of large strongyles that infect horses: Strongylus vulgaris, Strongylus endentatus and Strongylus equinus. Of the three types of large strongyles, S. vulgaris—the bloodworm—causes the most severe disease in horses.

Marek’s Disease
Moraxella bovis
Muskuloskeletal pain and inflammation

Causes of musculoskeletal pain in horses include osteoarthritis, laminitis, navicular disease and bowed tendon. Equine musculoskeletal pain often results from inflammation, with its hallmark signs of heat, swelling and redness.

Mycoplasma Pneumonia
Myositis (Selenium-Tocopherol Deficiency) Syndrome

Also called ‘white muscle disease’ or nutrition myodegeneration. Caused by a deficiency of selenium and vitamin E, this degenerative disease affects skeletal and cardiac muscle.

Newcastle Disease
Nodular Worms
Otitis externa
Pasteurella haemolytica and Pasteurella multocida

The equine pinworm, Oxyuris equi, their larvae are known to cause inflammation in the large intestine. The most common problem associated with pinworms is itching of the anus area caused by eggs deposited and adhering to the skin, which may progress to tail-rubbing.

Porcine Parvovirus
Potomac Horse Fever (PHF)

Potomac horse fever (PHF) affects the small and large intestines. The disease has also been seen sporadically in cats and dogs.

Pseudomonas aeruginosa

Rabies is a rare but fatal viral disease that attacks a horse’s neurologic system and can be transmitted to people and other animals.

Red Stomach Worms
Rotavirus Scours
Small Intestinal Worms
Small Strongyles

Small strongyles, or cyathostomins, are internal parasite extremely common and almost all grazing horses are infected.

Small Strongyles

A small red worm that affects cattle and grazing animals. They have been found in the intestines, cecum and colon.

Stomach Worms
Strangles (Streptococcus equi)

Strangles is a highly contagious disease that produces abscessation of the lymphoid tissue of the upper respiratory tract.

Taenia Tapeworm

Tetanus is an often-fatal disease caused by the toxin produced by the anaerobic, spore-forming bacterium Clostridium tetani. C. tetani organisms are abundant in soil, making infection an ever-present risk.


Tetanus is caused by the toxin produced by the bacterium Clostridium tetani. that causes stiffness in limbs and affects the central nervous system.

Venezuelan Encephalomyelitis

Early clinical signs of encephalitis include marked depression and high fever. Other signs of acute disease are impaired vision, lack of coordination, inappetence, circling, restless excitement, dyspnea and frequently paralysis.
