Paolo Casali, Giorgio Trinchieri. The evolution and epidemiology of influenza A virus (IAV) infections in swine have been integrally tied to the segmented nature of the genome of the virus, which facilitates gene reassortment, and to the adaptability of these genes through mutation, which sometimes facilitates replication in a new host. <>>> 0000014853 00000 n 0000001608 00000 n 1 0 obj Pathophysiology Of Infection And Inflammation.
