FIG. 2.
Retinal function analysis of wild-type and plcR-deficient Bacillus endophthalmitis. ERG was performed every 6 h throughout the course of infection. Rapid decreases in b-wave amplitude were observed in eyes infected with wild-type Bacillus strains for 18 h, while gradual decreases were observed over a 42-h period in eyes infected with plcR mutant strains. All values are means ± SEM for four or more eyes per group. BC WT, B. cereus ATCC 14579; BCplcR::kanR, plcR-deficient mutant of B. cereus ATCC 14579; BT WT, B. thuringiensis BT407; BTplcR::kanR, plcR-deficient mutant of B. thuringiensis BT407.
