Ross River virus causes an age-dependent and virus strain-dependent destructive infection of striated muscle and connective tissue in limbs and joints and hind limb paralysis in mice. This is not a perfect model of the debilitating arthritis, arthralgia seen in infected humans, but nevertheless there are merits to the model since the pathogenesis of alphavirus-induced arthritic disease in humans is not well understood. Here Ross River virus virions are budding from the plasma membrane of hind limb muscle cells 5 days post infection. Magnification approximately x40,000.
