Dynamics of virus shedding and antibody responses in influenza A virus-infected feral swine.


ABSTRACT: Given their free-ranging habits, feral swine could serve as reservoirs or spatially dynamic 'mixing vessels' for influenza A virus (IAV). To better understand virus shedding patterns and antibody response dynamics in the context of IAV surveillance amongst feral swine, we used IAV of feral swine origin to perform infection experiments. The virus was highly infectious and transmissible in feral swine, and virus shedding patterns and antibody response dynamics were similar to those in domestic swine. In the virus-inoculated and sentinel groups, virus shedding lasted ??6 and ??9?days, respectively. Antibody titres in inoculated swine peaked at 1?:?840 on day 11 post-inoculation (p.i.), remained there until 21 days p.i. and dropped to
