Advances in the genomics of ticks and tick-borne pathogens

Ticks and the diseases for which they are vectors engage in complex interactions with their mammalian hosts. These interactions involve the developmental processes of tick and pathogen, and interplay between the defensive responses and counter responses of host, tick and pathogen. Understanding these interactions has long been an intractable problem, but progress is now being made thanks to the flood of genomic information on host, tick and pathogen, and the attendant, novel experimental tools that have been generated. Each advance reveals new levels of complexity, but there are encouraging signs that genomics is leading to novel means of parasite control.
