Contact transmission of H4N6 AIVs in guinea pigs.

Abstract

<p>Three guinea pigs were intranasally inoculated with 10⁶ EID₅₀ of A/mallard/Beijing/10/2016 (A) or A/mallard/Beijing/16/2016 (B) viruses. At 24 hpi, the inoculated guinea pigs were placed in a cage with three naive guinea pigs. Nasal wash titers are plotted as a function of time post-inoculation. Titers of intranasally inoculated animals are represented by solid lines and filled squares; titers of exposed guinea pigs are shown with dashed lines and filled triangles.</p
