Abstract : Preimmunization of mice with salivary gland homogenate (SGH) of long-term colonized (F29) female Phlebotomus papatasi Scopoli (Diptera: Psychodidae) induced protection against Leishmania major Yakimoff & Schokhor (Kinetoplastida: Trypanosomatidae) co-inoculated with the same type of SGH. In contrast, preimmunization of mice with SGH of wild-caught female P. papatasi did not confer protection against L. major co-inoculated with the same type of SGH. Similarly, SGH from recently colonized (F1) female P. papatasi did not protect mice against L. major. These results suggest that when developing a sand fly saliva-based vaccine, the natural vector populations should be considered.
