Eastern equine encephalomyelitis (EEE) was the cause of heavy mortality in coturnix quail (Coturnix coturnix) reared commercially in South Carolina. The birds showed depression, tremor, and partial paralysis that advanced into complete paralysis, torticollis, and death within a few hours. The only consistent lesion on necropsy was a catarrhal enteritis in the duodenal area. The disease spread rapidly to all pens throughout the two houses on the farm in all birds over 2 weeks old, and mortality ranged from 40 to 90% in the various pens within the house. Total mortality exceeded 90,000 birds. Age groups on the farm ranged from 1 day to 8 weeks, at which time the birds went for slaughter. It appears that the initial infection was spread by cannibalism. EEE was diagnosed by isolating the virus in fertile eggs and suckling mice, with subsequent identification by complement-fixation. This is the first documented case of EEE in coturnix quail.
东部马脑炎（EEE）是南卡罗来纳州商业化养殖的鹌鹑（日本鹌鹑）大量死亡的原因。这些鸟表现出抑郁、震颤和部分麻痹，数小时内发展为完全麻痹、斜颈并死亡。尸检时唯一一致的病变是十二指肠区域的卡他性肠炎。疾病迅速传播到农场两栋鸡舍的所有鸡笼中所有2周龄以上的鸟类，鸡舍内不同鸡笼的死亡率在40%至90%之间。总死亡鸟类超过90000只。农场的鸟龄从1天到8周不等，8周时送去屠宰。最初的感染似乎是通过同类相食传播的。通过在受精蛋和乳鼠中分离病毒，并随后通过补体结合进行鉴定，确诊为东部马脑炎。这是有记录以来鹌鹑感染东部马脑炎的首例病例。
