2003年和2004年，在墨西哥尤卡坦半岛进行了西尼罗河病毒（WNV）感染脊椎动物的监测。对金塔纳罗奥州科苏梅尔岛的144匹马、尤卡坦州梅里达动物园的61种415种脊椎动物（257种鸟类、52种哺乳动物和106种爬行动物）和坎佩切州卡门城的7种养殖鳄鱼的血清进行了黄病毒抗体测定。科苏梅尔岛上的90匹（62%）马对黄病毒有表位阻断酶联免疫吸附试验（ELISA）抗体，其中75匹（52%）通过空斑减少中和试验（PRNT）对西尼罗河病毒呈血清阳性。在梅里达动物园的13只动物（3%）中也检测到黄病毒的阻断ELISA抗体，包括7只鸟类和2只哺乳动物（美洲虎和郊狼）PRNT对西尼罗河病毒呈血清阳性。坎佩切州的六只（86%）鳄鱼有PRNT确认的WNV感染。所有动物在血清采集时均健康，无WNV样疾病史。
Surveillance for evidence of West Nile virus (WNV) infection in taxonomically diverse vertebrates was conducted in the Yucatan Peninsula of Mexico in 2003 and 2004. Sera from 144 horses on Cozumel Island, Quintana Roo State, 415 vertebrates (257 birds, 52 mammals, and 106 reptiles) belonging to 61 species from the Merida Zoo, Yucatan State, and 7 farmed crocodiles in Ciudad del Carmen, Campeche State were assayed for antibodies to flaviviruses. Ninety (62%) horses on Cozumel Island had epitope-blocking enzyme-linked immunosorbent assay (ELISA) antibodies to flaviviruses, of which 75 (52%) were seropositive for WNV by plaque reduction neutralization test (PRNT). Blocking ELISA antibodies to flaviviruses also were detected in 13 (3%) animals in the Merida Zoo, including 7 birds and 2 mammals (a jaguar and coyote) seropositive for WNV by PRNT. Six (86%) crocodiles in Campeche State had PRNT-confirmed WNV infections. All animals were healthy at the time of serum collections and none had a history of WNV-like illness.
