从美国密西西比河迁徙野鸭泄殖腔中分离到的正型和副流感病毒包括3株甲型流感病毒(Hav6、Hav1、Hav6 NL、Hav7Neq2)和新城疫病毒。一种流感病毒A/鸭子/孟菲斯/546/74具有Hav3血凝素，但神经氨酸酶不被任何已知的流感抗血清抑制。该病毒的神经氨酸酶与A/DAD/GDR/72(H2 N？)、A/TURKY/Ontario/7732/66(HAV5 N？)、A/DAD/乌克兰/1/60(HAV3 N？)上的神经氨酸酶相关。和A/土耳其/威斯康星州/68。这组流感病毒上的神经氨酸酶被建议命名为Nav6。A/鸭子/孟菲斯/546/74流感病毒引起5只鸭子中的1只眼睛分泌物，并在粪便中排泄10天；在20度的粪便样本中，它最多稳定3天。对禽类流感的生态研究显然应该包括从粪便中分离病毒的尝试。粪便-口腔传播是流感病毒从野鸟传播到其他动物[包括人类]的一个有吸引力的解释。
Ortho- and parainfluenza viruses isolated from the cloacas of migrating feral ducks shot on the Mississippi flyway [USA] included 3 strains of influenza A virus (Hav6, Hav1, Hav6 Nl, Hav7 Neq2) and Newcastle disease virus. One influenza virus, A/duck/Memphis/546/74, possessed Hav3 hemagglutinin, but the neuraminidase was not inhibited by any of the known influenza antisera. The neuraminidase on this virus was related to the neuraminidases on A/duck/GDR/72 (H2 N?), A/turkey/Ontario/7732/66 (Hav 5 N?), A/duck/Ukraine/1/60 (Hav3 N?) and A/turkey/Wisconsin/68. The neuraminidase on this group of influenza viruses is proposed to be designated Nav6. The A/duck/Memphis/546/74 influenza virus caused an ocular discharge in 1 of 5 ducks and was shed in feces for 10 days; it was stable in fecal samples for up to 3 days at 20.degree. C. Ecological studies on influenza in avian species should apparently include attempts to isolate virus from feces. Fecal-oral transmission is an attractive explanation for the spread of influenza virus from feral birds to other animals [including man].
