日本脑炎（乙脑）病毒的感染是一个经常夏末现象之间雏鸟在东京附近的2个鹭科种群。在1952-1956年期间，每年的7月底和8月初首次发现可通过病毒恢复或抗体出现来证明的禽感染，实际上，这与在蚊子中证明乙脑病毒是一致的。禽流感病毒传播过程中感染的频率（血凝抑制抗体测定）范围从0.01至0.47，一直是更大的黑冠夜鹭比羽毛或小白鹭。1955年在名古屋附近的两个群体中的鹭科昆虫感染在发病率和时间上与东京附近的相似。除鸬鹚外，没有获得其他鸟类感染的明确证据，虽然日本野鸟的血清学调查表明广泛参与，但其他鸟类传播乙脑病毒的相对效率尚不清楚。
Infection with Japanese encephalitis (JE) virus was a regular late-summer phenomenon among nestlings at 2 ardeid colonies near Tokyo. Avian infection demonstrable by recovery of virus or appearance of antibody was first found in late July and early August of each year during 1952-1956 and was, for practical purposes, coincident with the demonstration of JE virus in mosquitoes. Frequencies of avian infection during virus dissemination (as measured by hemagglutination inhibition antibody) ranged from 0.01 to 0.47, being consistently greater in Black-crowned Night Herons than in Plumed or Little Egrets. Ardeid infection in 2 colonies near Nagoya in 1955 was similar in incidence and timing to that near Tokyo. Except for cormorants, no clear-cut evidence for infection of other bird species was obtained, and while serologic survey of Japanese wild birds suggests widespread involvement, the relative efficiency of other bird species for dissemination of JE virus is unknown.
