| Encephalomyocarditis Virus (EMCV)is a member of the genus ''Cardiovirus'' of the family ''Picornaviridae''.
| |
| It's said that the ''Picornavirus''infects many animal species, including pigs, rodents, cattle, elephants, raccoons, marsupials, and primate such as baboons, monkeys, chimpanzees, as well as humans.
| |
| There are two types of ''Encephalomyocarditis Virus''. One is ''Encephalomyocarditis Virus'' type '''A''', which causes reproductive problems.
| |
| The other one is ''Encephalolmyocarditis Virus'' type '''B''', which causes heart failure in pigs.
| |
| African elephants were the first species that were infected with the virus.
| |
| The first outbreak ever seen was in South Africa in 1993.
| |
| Between December 1993 and August 1994, a number of acute deaths occurred in free-ranging African Elephants in the Kruger National Park KNP.

| == Genome and Structure ==
| |
|
| |
|
| |
|
| |
| The main host of ''Encephalomycarditis Virus'' (EMVC) are the rat and mouse.
| |
| The virus is passed through fecal-oral transmission.
| |
| This was discovers after a large population explosion in rodents was documented during a period of time in which a large amount of elephants were dying.
| |
| ''Encephalomyocarditis Virus'' (EMCV) attacks many animals, but pigs have been studied and are said to be the most susceptible species.
| |
| This virus causes acute myocarditis and sudden death in preweaned pigs, whereas trans placental infections of sows cause fetal mummification, abortion, still birth, and neonatal death.
| |
|
| |
| == Cell Structure and Metabolism ==
| |
|
| |
|
| |
| When humans are infected with this virus, the symptoms they may be face with include fever, neck stiffness, lethergy, delirium, headches, and vomiting.
| |
| In primated such as gibbons and owl monkeys, ''Encephalomyocarditis Virus'' can cause necrotizing and interstitial myocarditis.
| |
| Transmission and pathogenesis occurs by :incubation from nine to ten days, oral, fecal and urine contamination of food, subclinical infections, replication in myocardial calls and kills them.
| |
|
| |
| Some diagnoses may be antermortem due to rapid clinical course, gross lessions such as pale streaks in the myocardium, hydrothorax, hydropericardium, pulmonary edema, froth in tracheobrochial tree.
| |
| Other diagnoses are ''Histopathology: myocardial degeneration and necrosis with lymphocytic infiltrates, virus particles may be visible on electron microscopy, definitive diagnosis: virus isolation, PCR, mouse inoculation, serological test for antibodies available''

| == Ecology and Pathology ==
| |
|
| |
|
| |
| The only treatment I have read about it not actually a treatment, but prevention, the oil-adjuvant Encephalomyocarditis vaccine.
| |
| This vaccine has been given to elephants, mice and pigs so far.
| |
| Also, scientists are finding that controlling the rodent population is crucial to preventing the spread of this disease.
| |
| Immune prophylaxis is considered to be another one of the effective strategies for controlling this virus in pigs and other animals who may possibly carry the virus.
| |
| In humans it's very rare to get this virus; you're more likely to get it if you work like in laboratories or aseptic meningitis, polio like syndrome.
| |
| However, in the end, further studies are needed.
