Myxomatosis is the name of the severe and often fatal disease in European rabbits caused by the myxoma virus. Different strains exist which vary in their virulence. The Californian strain, which is endemic to the west coast of the United States and Baja in Mexico, is the most virulent, with reported case fatality rates approaching 100%. [4]
Aedes vexans is a known vector of Dirofilaria immitis (dog heartworm), myxomatosis (a deadly rabbit viral disease), and Tahyna virus, a seldom-diagnosed Bunyaviridae virus, which affects humans in Europe, causing a fever which disappears after 2 days, but afterward can cause encephalitis or meningitis.
In order to curb with rabbit overpopulation, myxoma virus, a lethal species-specific poxvirus responsible for myxomatosis in rabbits, was deliberately released in South Australia in 1950. This led to a 90% decrease in rabbit populations, and the disease became endemic in a span of five years.
A rabbit displaying signs of myxomatosis. The European rabbit is the only species to be fatally affected by myxomatosis. The most lethal strain has a five-day incubation period, after which the eyelids swell, with the inflammation quickly spreading to the base of the ears, the forehead, and nose. At the same time, the anal and genital areas ...
Myxoma virus is a poxvirus in the genus Leporipoxvirus. The two broad geographic types of myxoma virus are Californian and South American. Californian myxoma virus is found on the West Coast of the United States, the Baja Peninsula of Mexico, and the southwest coast of Canada. South American or Brazilian myxoma virus is found in South and ...
A legal vaccine exists in Australia for RHD, but no cure is known for either myxomatosis or RHD, and many affected pets have to be euthanized. In Europe, where rabbits are farmed on a large scale, they are protected against myxomatosis and calicivirus with a genetically modified virus [38] developed in Spain.
Paul-Félix Armand-Delille (3 July 1874 – 4 September 1963) was a French physician, bacteriologist, professor, and member of the French Academy of Medicine.He is best known for attempting to protect his crop from rabbits by releasing a pair of rabbits infected with Myxoma virus on to his farm in northern France.

Myxomatosis is a virus disease of rabbits which can be fatal. The symptoms are swelling of the eyelids and lips, conjunctivitis and the formation of skin tumours on the face, ears and limbs. The rabbit flea acts as a vector for the disease and the virus has been shown to remain viable in the flea's mouthparts for at least one hundred days. [5]
