M. marinum ΔwhiB4 was attenuated in zebrafish. (A) Zebrafish (15 per group) were infected with indicated strain at 104 CFU bacteria per fish, and were monitored for mortalities over a 40-day period. The survival curves were plotted using the Kaplan-Meier method and differences between curves were analyzed using the log-rank test. All fish infected with ΔwhiB4 or PBS survived. The survival curve of the ΔwhiB4 group was significantly different to those of WT (p = 0.0005) or the complemented strain (p < 0.0001). A similar result was found in another independent experiment (B).
