D. melanogaster tep2 and tep6 mutants display variable number of total hemocyte counts and increased hemocyte viability compared with control flies (w1118) after Photorhabdus infection. According to the hemocyte counting protocol, total number of hemocytes (total cells/ml) in tep2 and tep6 mutants with control flies after 18 h of injection with 1XPBS, (A) P. luminescens (Pl) or (B) P. asymbiotica (Pa). The percentage of total viable cells in the control and tep mutant flies at 18 hpi with 1XPBS, (C) P. luminescens and (D) P. asymbiotica. Significant differences are indicated with asterisks (*p < 0.05, **p < 0.01, ***p < 0.001). Bars show the means from 3 independent experiments and error bars represent standard deviations.
