Abstract

Leishmaniasis represents an important public health problem in Ethiopia with heterogeneous clinical manifestations
ranging from self healing cutaneous form (CL), mutilating mucocutaneous (MCL) and metastasizing diffused lesions
(DCL) to a life-threatening visceral leishamaniasis (VL). Leishmania aethiopica is a usual etiological agent of CL while L.
donovani is considered the sole agent of VL in the country. The main transmission mode of these protozoan parasites is by
the bite of infected female phlebotomine sand fly in the genus Phlebotomus. Even though Ethiopian CL is believed to be
zoonotic with rock hyraxes as main reservoirs of the parasite, the transmission cycle of VL remains unclear and traditionally
believed to be anthroponotic. As part of a study on the ecology and transmission dynamics of VL in Ethiopia, we investigated
the role of domestic (E.g cattles, dogs) and wild (e.g rodents) animals in leishmaniasis cycle at endemic and non-endemic
settings. Molecular techniques targeting two genes (kDNA and ITS1) of the parasite were used to determine natural infection.
Moreover, serological procedures (anti-L. donovani IgG and anti-sand fly saliva antibodies in peripheral blood) were used as
a marker of exposure to the parasite and probable vectors. Our findings could open insight in the involvement of animals for
epidemiology of Ethiopian leishmaniasis at certain sort of reservoir system or as potential blood source for sand fly vectors.
