A collection of EST clones from female tick Amblyomma americanum salivary glands was hybridized to RNA from different feeding stages of female tick salivary glands and from unfed or feeding adult male ticks. In the female ticks, the expression patterns changed dramatically upon starting feeding, then changed again towards the end of feeding. On beginning feeding, genes possibly involved in survival on the host increased in expression as did many housekeeping genes.

Ticks are obligate ectoparasites that feed on a variety of hosts including mammals, birds and reptiles. Prolonged attachment on the host and an ability to transmit a wide variety of pathogens are the special features of tick feeding. Salivary glands are the major route for secretion of excess fluid, several proteins, and factors that counteract the host immune response and hence play a significant role in the success of tick feeding.

The rapid development of new genetic tools has boosted the gene discovery machinery. RNA interference (RNAi), a gene silencing process, has been recently used in several eukaryotic organisms to elucidate the function(s) of unknown genes and biochemical pathways. We used the dsRNA technique in Amlyomma americanum female ticks to test the applicability of the RNAi approach in ticks.
