  1. SHR, somatic homologous recombination; FSM, frame-shift mutation; ▪, no change (P > 0.05) compared to uninfected control; ↑↑, significant increase (P < 0.05) compared to uninfected control; ↓↓, significant decrease (P < 0.05) compared to uninfected control; ↑, increase, but not significant (P > 0.05) compared to uninfected control; ↓, decrease, but not significant (P > 0.05) compared to uninfected control; ▫, not analysed
