Sera from 360 ciconiform and pelecaniform birds collected in Florida (USA) from 1974 to 1990 were tested for serum neutralizing (SN) antibodies to eastern equine encephalitis (EEE), St. Louis encephalitis (SLE), and Everglades (EVE) viruses. Serum neutralizing antibodies to EEE virus were detected in 2%, to SLE virus in 7%, and to EVE virus in none of the samples. Pelecaniform birds (16%) had a higher antibody prevalence (P < 0.02) for SLE virus than did ciconiform birds (5%). Virus could not be isolated from 67 samples. Nestling birds with SN antibodies to both EEE and SLE viruses were found in both fresh water and marine colonies. Antibodies were more prevalent in adult and fledged juvenile birds than in nestlings.
1974年至1990年期间在美国佛罗里达州采集的360份鹳形目和鹈形目鸟类血清，检测了针对东部马脑炎（EEE）、圣路易斯脑炎（SLE）和大沼泽地（EVE）病毒的血清中和（SN）抗体。在2%的样本中检测到针对EEE病毒的血清中和抗体，7%的样本中检测到针对SLE病毒的血清中和抗体，而所有样本中均未检测到针对EVE病毒的血清中和抗体。鹈形目鸟类（16%）针对SLE病毒的抗体阳性率高于鹳形目鸟类（5%）（P < 0.02）。从67份样本中未分离到病毒。在淡水和海洋栖息地的雏鸟中均发现了对EEE和SLE病毒均具有SN抗体的雏鸟。抗体在成年鸟和羽翼丰满的幼鸟中比在雏鸟中更为普遍。
