| myxoma virus | <virology> A poxvirus (see Poxviridae) that causes myxomatosis. Originally isolated from a species of wild rabbit, Sylvilagus in Brazil, in which it causes a mild nonfatal disease, it was found to be 99% fatal in the European rabbit Oryctolagus. It causes the characteristic, sub cutaneous gelatinous swellings, myxomata and usually kills in 2-5 days. It has been used to control rabbit populations in Australia and Britain, but there are signs that they have developed immunity. (18 Nov 1997) |
