First insights into the genetic diversity and origin of Leishmania infantum in Mont Rolland (Thiès region, Senegal).

Visceral leishmaniasis is not endemic in West Africa. However, high seroprevalence of Leishmania infantum infection (one of the Leishmania species that cause visceral leishmaniasis) was detected in dogs and humans in the Mont Rolland community (close to Thiès, Senegal), despite the lack of reports concerning human clinical cases. Our aim was to genetically characterize this L.

Seroprevalence of Leishmania infantum in a rural area of Senegal: analysis of risk factors involved in transmission to humans.

Whereas Leishmania infantum, the agent of visceral leishmaniasis (VL), is well known in North Africa, very limited data exist on its spread in West Africa, where mainly cutaneous leishmaniasis has been widely reported. Nevertheless, dogs infected with L. infantum were recently found in the Mont Rolland District in Senegal.
