Similarly, in steroid treated mice, we observed that genes metAT (AFUA_2G13630), cysAT (AFUA_1G09470), isa1 (AFUA_4G10690), and ssuA (AFUA_7G01790) had higher expression at mid- (24 h) and late (72 h) times after infection (Figure 3e and Fig. S2b purple box), indicating that they may be more relevant for the progression and maintenance of infection than for its initiation. This evidence concerns the gene ISCA1 and infection.
