On the other hand, mice infected with CHUGA-Ft6∆fur survived a significantly longer time (p < 0.001 compared to CHUGA-Ft6 and CHUGA-Ft6∆fur + fur whatever the route of infection), that is, 140 h and more than 200 h for the last animal infected by IP and by IN routes, respectively. The gene discussed is FURIN; the disease is infection.
