Gross necropsy lesions are minimal in the uncomplicated respiratory form of PRRS, but interstitial pneumonitis is a consistent histopathologic finding. There are no gross or histopathologjc lesions noted in aborted or stillborn fetuses.
Microscopic lesions of the fetus
and placenta include umbilical vasculitis, interstitial
pneumonia, myocarditis and pulmonary arteritis but are
inconsistent and not diagnostic for PRRS (Lager and
Ackermann, 1994; Lager and Halbur, 1996; Rossow et
al., 1996b). There may be residual effects of PRRS
virus infection in sows manifest as a reduced conception
rate (Lowe et al., 2006).
