1840. Pool screen PCR for estimating the prevalence of Leishmania infantum infection in sandflies (Diptera: Nematocera, Phlebotomidae). (Abstract)

Pool screen PCR for estimating the prevalence of Leishmania infantum infection in sandflies (Diptera: Nematocera, Phlebotomidae). Prevalence studies of infection in the sandfly vector can be used as an indicator of a change in the intensity of Leishmania transmission. However, these studies are difficult to carry out as prevalence in the vector is usually low and its estimation requires a large number of sandflies to be dissected. Our objective was to establish whether a L. infantum-specific
