In 1 of 2 outbreaks of eastern equine encephalomyelitis virus (EEEV) infection in swine, 280 of 350 pigs died. Histopathologic findings in the brain were typical of EEEV infection. In addition, multifocal necrosis and inflammation were seen in the myocardium. Follow-up investigation in 1 of the herds revealed antibody response to EEEV in surviving pigs and in adult swine. Growth retardation was noticed in surviving pigs. Histologic examination revealed mild lesions in the brain of the survivors.
在猪群发生的两起东部马脑脊髓炎病毒（EEEV）感染疫情中，有一起疫情里350头猪中有280头死亡。脑部的组织病理学发现是EEEV感染的典型表现。此外，心肌出现多灶性坏死和炎症。对其中一个猪群的后续调查发现，存活猪和成年猪对EEEV有抗体反应。存活猪出现生长发育迟缓。组织学检查显示存活猪脑部有轻度病变。
