M.marinum ΔglpX is attenuated in zebrafish. (A) Survival curves of adult zebrafish during a 21-day infection course. Fish were intraperitoneally infected at an initial dosage of 104 CFU/fish of WT, ΔglpX, and complemented strain ΔglpX/C (glpX). (B) Zebrafish larvae were infected with WT (56 CFU), ΔglpX (168 CFU) and complemented strain ΔglpX/C (glpX) (26 CFU) carrying pTEC15 containing fluorescent protein Wasabi separately. Representative fluorescent images of infected larvae at 5 dpi. The arrow points to the formation of initial granuloma with fluorescent M. marinum inside. Bacterial burdens of infected larvae were determined by FPC at 4 dpi (C) and 6 dpi (D), OD = lg255/PixelValue, P values are calculated by an unpaired Student t test. (E) The relative transcription of inflammatory cytokines were measured by qRT-PCR using total RNA extracted from zebrafish. 0.01<*P≤0.05, 0.001<**P ≤0.01, ***P ≤0.001 by Kruskal-Wallis test and Dunn′s Multiple Comparison Test. |
