Figure 3From: Silencing of a putative immunophilin gene in the cattle tick Rhipicephalus (Boophilus) microplus increases the infection rate of Babesia bovis in larval progenyCumulative percentage of engorgement of R. microplus females injected with dsRNA to silence the immunophilin ( Imnp ) (black lozenge), serine protease inhibitor ( Spi ) (black square) or lipocalin ( Lpc ) (black triangle) genes and control females (white circle). The graphic shows the effect of gene silencing on engorgement and survival of female ticks throughout the feeding period. Asterisk (*) indicates difference between the control and the Spi dsRNA-injected groups as determined by Chi-squared test (P < 0.01).Back to article page
