FIG 6 .

Gig genes are required for virulence in G. mellonella. (A) G. mellonella larvae were infected with the strains indicated and monitored for survival as described in Fig. 1. (B) Growth of AB5075 with the empty vector (left gray bar) or the gigB mutant harboring the empty vector (white bar) or a complementing clone of gigB (right gray bar). (C) Growth of wild-type AB5075 (left gray bar) or the strains indicated harboring a hygromycin resistance gene (white bars) or a wild-type copy of the deleted gene at the Tn7 locus (center and right gray bars). In panels B and C, growth is depicted as described in the legend to Fig. 1. ****, P < 0.0001; ***, P < 0.001; **, P < 0.01.
