Fig. 5. Prophylactic and therapeutic efficacy of C12G6 in ferrets. Prophylactic and therapeutic efficacy of C12G6 in ferrets. (A to D) Virus titers in nasal washes from ferrets treated with C12G6 (20 mg/kg) or control antibody (C5G6) 1 day before (prophylactic groups) or after (therapeutic groups) intranasal infection with 1 × 107 TCID50 of B/Florida/4/2006 (A and B) or B/Brisbane/60/2008 (C and D). (E to H) Changes in body temperatures of ferrets treated with C12G6 (20 mg/kg) or control antibody (C5G6) 1 day before (prophylactic groups) or after (therapeutic groups) intranasal infection with 1 × 107 TCID50 of B/Florida/4/2006 (E and F) or B/Brisbane/60/2008 (G and H). Nasal washes were collected on the indicated days and titrated by TCID50 assay. Body temperatures are expressed as the percentage of baseline values. The black bars indicate mean values. Statistical analysis was performed by t test. *P < 0.05, compared to the control IgG–treated group. Chenguang Shen et al., Sci Transl Med 2017;9:eaam5752 Published by AAAS
