Research Abstract

Tick is a hematophagous arthropod which transmits canine Babesia protozoa, Babesia gibsoni. In this, the protozoa which taken by the parental ticks during the blood-feeding, shifts to next-generation larval ticks through an egg (transovarial transmission). In this research, two experimental systems including transovarial transmission and microarray analysis were established to analyze the gene expression profile of tick embryo parasitized by B. gibsoni. Here, we assumed that the expression of the genes constitutively expressing in the tick might be stable even though they were infected with the parasites.
