Table 3 Comparison of Rickettsia rickettsii gene expression in salivary glands and midgut of male and female ticks exposed to temperature upshift, blood-feeding or both stimuli simultaneously.

From: Virulence genes of Rickettsia rickettsii are differentially modulated by either temperature upshift or blood-feeding in tick midgut and salivary glands

 

Salivary glands

Midgut

 

Genes modulated or not in both genders

Genes exclusively modulated in one gender

Genes modulated or not in both genders

Genes exclusively modulated in one gender

Temperature upshift

40 (05 m and 35 ns)

15

52 (07 m and 45 ns)

16

Blood-feeding

34 (17 m and 17 ns)

21

42 (19 m and 23 ns)

28

Temperature upshift + Blood-feeding

40 (26 m and 14 ns)

16

30 (20 m and 10 ns)

36

  1. m, modulated in relation to control. ns, no significant differences in relation to control
  2. Controls, unfed ticks at 25 °C (G1) for temperature upshift and combined effects of temperature upshift and blood feeding; unfed ticks at 35 °C (G2) for blood feeding
