Abstract
In 2007, nonsuppurative encephalitis was identified in a killer whale at a Texas, USA, marine park. Panviral DNA microarray of brain tissue suggested West Nile virus (WNV); WNV was confirmed by reverse transcription PCR and sequencing. Immunohistochemistry demonstrated WNV antigen within neurons. WNV should be considered in cases of encephalitis in cetaceans.
摘要
2007 年，在美国德克萨斯州的一个海洋公园中，一头虎鲸被诊断患有非化脓性脑炎。脑组织的泛病毒 DNA 微阵列检测提示存在西尼罗河病毒（WNV）；通过反转录 PCR 和测序进一步证实了 WNV 的存在。免疫组织化学显示神经元内存在 WNV 抗原。WNV 应被视为鲸类动物脑炎的病因之一。
