Extended Data Fig. 1: Antibiotic treatment of BCG i.v.–vaccinated mice does not unmask intergenerational resistance.
From: Lack of evidence for intergenerational inheritance of immune resistance to infections
a, Mice were iv-vaccinated with BCG-Tice (1 × 106 CFU). After one-month BCG vaccination, to eliminate live BCG, mice were treated with Antibiotics (INH + Rifampicin) for 4wks, followed by a 2wks wash-out period. Subsequently, naïve or BCG-vaccinated mice were mated and the adult offspring were infected with M. tuberculosis (~50 CFU, H37Rv aerosol, male offspring) or IAV sublethal (50PFU) or lethal (90PFU) dose (intranasally; female offspring). b, Lung and spleen CFU at 4wks post Mtb infection. c, Lung PFU 3d post sublethal IAV infection. d, F1.2 and F1.3 offspring from BCG-vaccinated and unvaccinated mice were treated with the antibitics and then were infected with Mtb or IAV. e, Survival after lethal IAV infection in F1.2 and F1.3. F1.2 (f) and F1.3 (g) Lung and spleen CFU 4wks post Mtb infection. All CFU data are displayed in log scale. There was no statistically significant difference between groups.
