A classical approach immunizing cattle with total ovarian proteins was followed.
The detection of ovarian proteins was achieved by ELISA plates coated with proteins from larval homogenates.
Several immunogenic proteins such as Vitellogenins and yolk Cathepsin were identified.
Vitellogenin-1 and Vitellogenin-2 transcripts are synthesized in the ovaries of R. microplus.
Vitellogenins represent attractive candidates for development of anti-tick vaccines.
