Determination of Annexin V binding on hemocytes from G. mellonella larvae injected with H. pylori bacteria suspensions, BCFs or purified VacA cytotoxin. Percentage of Annexin V-positive hemocytes of G. mellonella larvae after 3 h from injection with bacterial suspensions of wild-type strain G27 and their mutants (panel A), bacterial suspensions of wild-type 60190 and their mutants (panel B), BCFs of wild-type strain G27 and their mutants (panel C), BCFs from wild-type 60190 and their mutants (panel D) and purified VacA cytotoxin (panel E). As control, Annexin V binding on non-treated hemocytes was always performed. Values represent the mean (±SEM) of three independent experiments. + P < 0.05 vs control (ANOVA);* P < 0.05 vs wild-type strain (ANOVA). CTRL, control; BCF, broth culture filtrate.
