title: [The taxonomic status of Leishmania garnhami, indicated by its pattern of development in the vector].
abstract: Under experimental conditions, the developmental pattern of Leishmania garnhami in its vector Lutzomyia townsendi, was established following daily dissections between the 1st and the 12th day post-infection. L. garnhami succeeded in establishing initial infections in any of the gut regions and in the Malpighian tubules of infected sandflies. Similar behavior was observed in infected Lu. longipalpis. The distribution of L. garnhami in the digestive tract of infected flies, is different to that observed in species of the L. mexicana and L. braziliensis complexes. The susceptibility of Lu. townsendi to infection by L. mexicana, L. braziliensis and L. garnhami is discussed. It is concluded that L. garnhami, according to its behaviour in the vector, must be considered different from the l. mexicana complex, and that its developmental pattern differs from that of the Suprapylaria, because it invades the hind triangle and also from the species of the Peripylaria by its invasion of the Malpighian tubules.
