Encephalomyocarditis virus is a zoonotic agent.
Encephalomyocarditis (EMC) is caused by Cardioviruses in the family Picornaviridae. EMCV, while considered a rodent virus, may infect a wide range of mammals including non-human primates, elephants, pigs and humans. Outbreaks of disease due to EMCV infection have been most frequently reported in pigs and wildlife species held in captivity. EMCV is shed in the faeces and urine of rodents, which contaminates food and water supplies of other mammals. Outbreaks of disease are usually associated with severe infestations of mice and, less commonly, rats.
Affected pigs typically present with a history of sudden death from cardiac insufficiency and cardiogenic pulmonary oedema. Other clinical signs may include fever, anorexia, lethargy, dyspnoea, trembling, staggering and paralysis. Mortality is higher in suckling pigs compared with older pigs. EMC viruses can cross the placenta in pigs and cause abortions, stillbirths and mummification.
Diagnosis is based on a combination of history, clinical signs, serology and histopathology.
