Descriptions of Infections

Eastern & Western encephalomyelitis : a deadly viral infection transmitted via mosquitoes. Clinical signs may include : fever, lethargy, impaired vision, aimless wandering, head pressing, circling, inability to swallow, paralysis, convulsions and death.

Tetanus : a disease caused by a toxin produced by the bacteria Clostridium tetani: Horses are the most sensitive species to tetanus infections. Transmitted to wounds in infected soil. Clinical signs may include: stiffness, spasms, difficulty walking ‘sawhorse stance,’ sweating and death.

Influenza: a viral infection causing respiratory disease. Highly contagious, spread by infected respiratory secretions. Inset is quick, with fever, coughing, nasal discharge, depression, anorexia and weakness.

Rhinopneumonitis: a viral infection causing respiratory disease and/or abortion. Spread by direct or indirect contact with infective nasal discharges, aborted fetuses, placentas, or placental fluids. Clinical signs may include: fever, nasal and/or ocular discharge, cough, depression and in appetence. Mares that abort usually do not show and previous signs, abortion occurs between 7 and 11 months gestation.

Strangles: a bacterial infection easily spread by discharges (inhaled or ingested) of infected horses. Clinical signs may include: fever, in appetence, nasal and/or ocular discharge, painful swallowing, abscesses of the lymph nodes of the neck (swelling under the jaw) and death.

West Nile virus: a viral infection transmitted by mosquitoes causing a encephalitis (swelling of the brain). Clinical signs may include: fever, depression, stupor, ataxia, reluctance to stand, hind limb weakness, muscle tremors and death.
