Figure 4. Four Genetic Changes Enable Transmissibility by Fleabite.

Figure 4

The number of CFU transmitted by fleas infected with the bacteria indicated was quantified at weekly intervals after a single infectious blood meal. Day 3 represents biofilm-independent early-phase transmission (EPT); later timepoints represent proventricular biofilm-dependent transmission. Numbers in parentheses associated with data points are the number of fleas that fed, and of those, the number that were completely or partially blocked. The maximum extent of proventricular infection achieved by the strains is shown at right.
