*West Nile virus (WNV) or Bagaza virus (BAGV) nucleic acids were identified by using real-time reverse transcription PCR (RT-PCR) or panflaviviral heminested RT-PCR, respectively, and amplicon (214 bp) sequencing. ECE, embryonated chicken egg; AF, allantoic fluid; NA, not analyzed; CM, chorioallantoic fluid; VS, viscera. †ECEs were infected with homogenates of various samples. ‡Samples from which full-length sequence of BAGV was obtained. §Tail, breast, and wing feathers from 1 partridge were analyzed.
