Survey of feline visceral leishmaniasis in Azarshahr area, north west of Iran, 2013.
Leishmania infantum is a causative agent of visceral leishmaniasis or kala-azar, which is endemic in some part of Iran. Azarshahr city located in East Azerbaijan province, North West of Iran, which is endemic for visceral leishmaniasis. This study aimed to investigate the possible reservoir role of cats for visceral leishmaniasis in the Azarshahr area. Totally 65 cats have been trapped alive from villages of Azarshahr county and their serum samples subjected to direct agglutination test (DAT) for L. infantum antibodies. Giemsa stained impression smears have been prepared for parasitological examination of spleen and liver tissue. Also liver and spleen samples of the cats have been cultured in Novy-MacNeal-Nicolle (NNN) medium and also used for PCR. None from 65 samples was positive in NNN culture, PCR and microscopic examination. Fifteen (23.07 %) out of 65 serum samples showed Leishmania specific antibody agglutination at 1:320 dilution or above, but all considered as negative because none of them confirmed by Giemsa stained smears, PCR and NNN culture. According to the findings of the present study, cats are not a reservoir for visceral leishmaniasis in the Azarshahr area.
