Meanwhile, during the Rossi strain infection (40% mortality between 3- and 4-days post-infection), where the animals survived for up to 72 h post-infection, the animals showed an increased expression of vimentin already in the first hours of the experiment (12, 24, and 36 h), with the highest amount of vimentin protein in the serum at 24 h post-infection. The gene discussed is VIM; the disease is infection.
