Figure Lengend Snippet: Host cell damage and virulence capacity of mutants in sugar nucleotide biosynthesis. (A) Mutants grown in +/− 25 μg/ml Dox screened for epithelial damage using A-431 cells by LDH assay. The mean LDH released at 24 h post co-incubation is shown for repressed mutants (grown in presence of Dox; blue bars) and No-Dox controls (red bars). Red and blue horizontal lines indicate the mean LDH activity for wild type control (No-Dox) and wild type grown in presence of Dox respectively. Welsh t-test used for statistical analysis; error bars represent standard error of mean; p**** < 0.0001. (B) Survival plots of G. mellonella larvae infected with C. albicans mutants in: (I) GDP-mannose, (II) UDP-glucose and (III) UDP- N -acetylglucosamine biosynthesis in presence (solid lines) and absence (dotted lines) of Dox. No killing or improved survival was observed for a number of repressed mutants. No killing was observed in control larvae injected with equivalent volume of PBS.
