FIG 3.
Body weight changes in infected animals. Six-week-old female BALB/c mice and DBA/2 mice and 4- or 8-week-old female Syrian hamsters were anesthetized and intranasally inoculated with 106 PFU of H3N2/2013 (A, left), H3N2/2014 (A, middle), H3N2/2016 (A, right), pdmH1N1/2013 (B, left), pdmH1N1/2014 (B, right), Victoria/2014 (C, left), or Yamagata/2014 (C, right) virus (n = 3 hamsters and n = 4 mice for each virus). The body weights of individual animals inoculated with viruses are depicted as a percentage of the body weight compared with that on day 0. Crosses indicate dead infected animals.
