<p>(<b>A</b>) Percentage of fleas that developed complete proventricular blockage. The mean and SD are indicated. (<b>B</b>) Mortality rate of uninfected (open symbols) and infected (closed symbols) <i>O</i>. <i>montana</i> (red symbols) and <i>X</i>. <i>cheopis</i> (blue symbols). (<b>C</b>) Percentage of <i>O</i>. <i>montana</i> (red symbols) and <i>X</i>. <i>cheopis</i> (blue symbols) still infected 7 and 28 days after an infectious blood meal. (<b>D</b>) Mean bacterial load in infected <i>O</i>. <i>montana</i> (blue symbols) and <i>X</i>. <i>cheopis</i> (red symbols) immediately after the infectious blood meal (day 0) and at 7 and 28 days after infection. The cumulative results of three independent experiments (n = 99 to 113 fleas each) are shown in (<b>A, B</b>); the results of each of the three experiments are plotted in (<b>C, D</b>). *<i>P</i> = 0.0003; **<i>P</i> < 0.0001 by Fisher’s exact test (two-tailed).</p>
