Abstract
Background: An epidemiological study was carried out on the vector(s) and reservoir(s) of cutaneous leishmaniasis in rural areas of Kalaleh District, Golestan Province during 2006 - 2007.
Methods: Totally 4900 sand flies were collected using sticky papers and were subjected to molecular methods for detection of leishmanial parasite.
Results: Phlebotomus papatasi was the common species in outdoor and indoor resting places. Employing PCR technique showed only 1 out of 372 P. papatasi (0.3%) was positive to parasite due Leishmania major. Sixteen rodent reservoir hosts were captured by Sherman traps and identified as Rhombomys opimus. Microscopic investigation on blood smear of the animals for amastigote parasites revealed 6(37.5%) infected rodents. Infection of these animals to L. major was then confirmed by PCR against rDNA loci of the parasite.
Conclusion: This is the first molecular report of parasite infection of both vector (P. papatas) and reservoir (R. opimus) to L. major. The results indicated that P. papatas was the primary vector of the disease and circulating the parasite between human and reservoirs, and R. opimus was the most important host reservoir for maintenance of the parasite source in the area.
