Virulence of MPXV Z-1979 and USA-2003 upon IN infection of CAST mice. (A) CAST mice (groups of n = 4 to 5) were mock infected or infected IN with 102 to 105 PFU of MPXV Z-1979 or USA-2003 and examined and weighed daily. The percentage of starting weights and survival are indicated. Bars indicate SD. (B) CAST mice (n = 4 to 5) were infected IN with 102 PFU of MPXV Z-1979 or USA-2003. On days 5 (d5) and 7 (d7), whole organs and organ pairs were removed, homogenized, and the total PFU determined by plaque assay. Bars represent geometric means. *P < 0.05 and **P < 0.01.
