Distribution Dermal leishmaniasis

Distribution Dermal leishmaniasis is essentially a zoonosis which occurs in scattered foci throughout the tropical and subtropical belts. Depending upon the locality it is known as Oriental sore, Aleppo button, Baghdad boil, Delhi sore, etc. Arid or even semi-desert terrain provides ideal habitats for the vector sandflies which spend the days in cool deep crevices in the ground, between rocks, in caves, cellars, house walls, etc.

Various species of rodents, such as the great gerbil of Eastern Iran and neighbouring parts of the USSR {Rhombomys opimus) are important animal resevoirs of L. (tropica) major. In the Mediterranean littoral, dogs and wild carnivores may be infected with L. tropica (minor).

Diagnosis may be assisted by the injection of an intra- dermal antigen prepared from cultured promastigotes of L. tropica or other dermatotropic species. This produces a typical cell-mediated response (Monte­negro test) in most cases of cutaneous disease. It is negative in the active stages
