Evaluating the host colonization properties of rec Sodalis . A) Number of recSodalis CFU (DNA equivalent) present in abdomen (solid red line) and thorax (solid black line) of Streptozotocin-treated flies injected with 1x107 CFU of Sod_pFliCpelBNb46fliC versus the total number of Sodalis CFU DNA equivalent (WT + recombinant Sodalis) present in abdomen (dashed red line) and thorax tissues (dashed black line). B) The number of recombinant and total Sodalis CFU (DNA equivalent) present in haemolymph (solid/dashed blue line) and midgut (solid/dashed grey line) were estimated as described above. Data points represent the mean recSodalis and total Sodalis CFU (DNA equivalent) ± SD present in the respective tissues of at least 5 individual flies at the time of sampling. The number of CFU (DNA equivalent) is represented in log scale on the y-axis.
