In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on Avery Island, Louisiana. Subsequent investigation revealed that more than 400 birds died. Severe peritoneal nematodiasis (Eustrongylides sp.) was found on postmortem examination. A nearby breeding rookery on the same island was apparently unaffected. Reasons for this selective mortality are presented. Three other reports of epizootic mortality due to Eustrongylides sp. have been reported. This is the first report of this type of epizootic in gulf-coast birds.
1985年5月，路易斯安那州艾弗里岛的大白鹭（白鹭属）出现了 epizootic 死亡情况。随后的调查显示，有400多只鸟死亡。尸检发现严重的腹腔线虫病（真圆线虫属）。同一岛屿附近的一个繁殖栖息地显然未受影响。本文阐述了这种选择性死亡的原因。此前已有另外三起关于真圆线虫属导致 epizootic 死亡的报告。这是墨西哥湾沿岸鸟类中此类 epizootic 的首次报告。
