Figure 1

Engorged weight of ticks after the experimental inoculations. PBS_PG is PBS + penicillin G sodium salt. H_wo is 5 × 1011 bacteria. H_PG is 5 × 1011 bacteria + penicillin G sodium salt. L_wo is 5 × 108 bacteria. L_PG is 5 × 108 bacteria + penicillin G sodium salt. The white circle in the figure represents the average engorged weight. The black circle in the figure represents each value.
