Evaluating host colonization after introduction of recSodalis via a thoracic injection, b thoracic injection combined with blood meal supplementation and c blood meal supplementation only. Graphs depict the number of recSodalis CFU (DNA equivalent) present in abdomen (dashed black line), thorax (dashed red line) and reproductive organs (dashed blue line) versus the total number of Sodalis CFU (DNA equivalent) (WT + recombinant Sodalis) present in abdomen (solid black line), thorax (solid red line) and reproductive organs (solid blue line). Data points represent the mean recSodalis and total Sodalis CFU (± SD) present in the different tissues of individual flies (n = 5) at the time of sampling. The number of CFU is represented in log scale on the y-axis
