[Experimental infection of Lutzomyia whitmani in dogs infected with Leishmania braziliensis braziliensis].

Lutzomyia (N.) whitmani was infected on leishmaniotic lesions of three out of nine dogs infected with Leishmania braziliensis braziliensis. The infectivity rates in these sandflies were 8.3% (1/12), 7.1% (1/14) and 1.8% (3/160), respectively. In addition, 180 Lu. whitmani fed on non-ulcerated regions of one of the infected dogs and none became infected. We emphasize the vector potentiality of Lu. whitmani for L.b. braziliensis in the endemic region of Três Braços, Bahia, Brazil.
