Under most circumstances there is no grossly visible lesion. During acute, generalized infections in mice, the liver may be enlarged and pale with hemorrhagic foci. Intestinal serosa can be irregularly reddened and mucosa congested (McCordock and Smith 1936). Mineralization of skeletal muscle and brown fat (Lussier 1975) and bloodtinged ascitic fluid (Olding et al. 1976) have also been observed. Mice infected as neonates are runted with thymic and splenic involution (Schwartz et al. 1975).
