Fig. 4From: Helicobacter pylori strains harboring babA2 from Indian sub population are associated with increased virulence in ex vivo study a–c Triple positive strains and even the babA2 positive only strains cause more apoptosis in AGS cells. a Apoptosis of AGS cells (a i, iv worked as controls) co-cultured with different genotypic variant i.e. a ii triple positive; a iii cagA +/vacA +/babA2 −; a v cagA −/vacA −/babA2 +; and a vi triple negative strains of H. pylori strains for 24 h (MOI is 100), stained with propidium iodide and analysed by flow cytometry. These figures are representative profile of at least three experiments. b, c Graphical representation of  % apoptotic cells (Sub G0 phase) infected with same group of strains were expressed as mean ± SEM. *P < 0.05 as compared between groupsBack to article page
