Leishmania is a genus of trypanosomatid protozoa and is the parasite responsible for the disease leishmaniasis.
Dear Raad
In several parts of the world cattle act as a reservoir for leishmaniasis. This is certainly the case in parts of South Asia like eastern Bangladesh and also Sudan, especially in those areas where Leishmania donovani produces a skin lesion but does not normally progress to severe visceral complications, and is often completely self limiting. I presume cattle also act as a reservoir in geographically close regions where the same parasite does produce visceral complications, e.g. western Bangladesh but I have no information on that.

Dear DR. Burgess , you may refer to work of Mohammad Shafiul Alam etal. 2011. Survey of domestic cattle for anti-Leishmania antibodies and Leishmania DNA in a visceral leishmaniasis endemic area of Bangladesh . in below link the paper .Thanks

Thanks for pointing this out. It is a newer source than I had been aware of. Older sources had certainly suggested cattle acted as reservoirs in these areas. It would be interesting to see if the cattle show positive reactions in the Jessore region of Bangladesh where visceral leishmaniasis is also common.
this is the answer for your question Dr Raad .
"Dr. Dia El Naiem assumes that cattle have strong complement fixation capacity, which would quickly kill the parasite".this answer was mentioned in Report of the Post Kala-Azar Dermal Leishmaniasis (PKDL) consortium meeting, New Delhi, India,27–29 June 2012.

The simple presence of antibodies against leishmania parasite does not indicate the cattle are reservoir. So far no reports available about the cattle role as reservoir of leishmaniasis. Remember, reservoir is one should continuously act as source for a disease causing agent.
Even in Turkey the researches have found that cattle are the most common reservoir for Leishmania infantum that causes Cutaneous leishmaniasis.
Dear Mayilsamy Muniaraj I wrote what Dr. Dia El Naiem assumed about this issue.
I know it doesn't mean that cattle act as reservoir hos for Leishmania.
clinical leishmaniasis occurs in cattle. It is not known that cattle will act as reservoir host. That not withstanding, if infected cattle were found in locality with an important vector population, such cattle will certainly be a source of pathogens that will be transmitted by the vector flies. This situation does not make cattle a reservoir in the real sense of the word.

Yes, cattle and other mammals act as a reservoir for Leishmania spp. if they at chronic stages and the vectors as stable fly distribution in this area.
