From: The tree shrew is a promising model for the study of influenza B virus infection
Influenza B viruses can replicate in tree shrews, ferrets and mice. Tree shrews (a), ferrets (b) and mice (c) were inoculated with 1.0 × 106TCID50 of virus intranasally. At 2, 4 and 6 days post inoculation (DPI), nasal washes were collected and virus titers were determined by tissue culture infectious dose 50% (TCID50) assay in Madin Darby canine kidney (MDCK) cells●Yamagata strain B/Guangzhou/12/2016 (Y12), ○Victoria strain B/Guangzhou/0215/2012 (V0215).
