Zusammenfassung:In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on A very 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. /// En mayo de 1985, en la isla A very del estado de Louisiana, E.U.A., se reportó una epizootia con aumento en la mortalidad en garzas comunes (Casmerodius albus). La investigación reveló que murieron más de 400 aves. A la necropsia se encontró una nematodiasis peritoneal severa (Eustrongylides sp.). Un criadero de aves situado cerca en la misma isla aparentemente no se vió afectado. Se presentan las razones de esta mortalidad selectiva. Se han reportado otras 3 epizootias con mortalidad debido a Eustrongylides sp. Este es el primer reporte de este tipo de epizootia en aves localizadas en la costa del golfo.
