The Lausanne strain of the myxoma virus causes the formation of large purple skin-nodules, a sign not seen in other strains. As happened in Australia, the virus has generally become less virulent and the wild rabbit populations more resistant subsequently. [1]
The success of the virus was found to be higher in dry areas, because of a benign calicivirus found in the colder, wetter areas of Australia, which was immunising rabbits against the more virulent form. [37] 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.

Nobivac Myxo-RHD, [24] made by MSD Animal Health, is a live myxoma-vectored vaccine that offers one-year duration of immunity against both RHDVa and myxomatosis. [citation needed] Vaccines against only the newer RHDV2 strain are: Eravac vaccine, manufactured by HIPRA, [25] protects rabbits against RHDV2 for a year.
Myxomatosis can also infect pet rabbits (the same species). Today's remaining feral rabbits in Australia are largely immune to myxomatosis. A strain of a second deadly rabbit virus, rabbit haemorrhagic disease (RHD), was imported to Australia in 1991 as a biological control agent, and was released accidentally in 1995, killing millions of rabbits.
Gripping tightly with your toes to keep a loose shoe in place can put additional strain on your plantar fascia, as can jamming your toes into a too-tight or too-narrow space. APMA Seal of Acceptance
Behind rising egg prices and shortages is a strain of highly pathogenic avian influenza (HPAI), known as H5N1, that killed 13.2 million commercial egg-laying hens in the month of December alone ...
The release of wild European rabbits in 1859 into Victoria, Australia for sport resulted in a rabbit plague. 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.
