Cutaneous leishmaniasis (CL) is endemic in Sardinia where 250 cases were reported from 1922 to 1988. The province of Sassari, in the north of the island, shows the highest number of cases. The vertical distribution of localities where cases had occurred is analysed and the age distribution of cases is given. Isolation of parasites was attempted in 12 cases, but successful growth of Leishmania was obtained from three cultures only. The stocks belonged to two different zymodemes of L. infantum: zymodeme Montpellier (ZMON) 24 and ZMON 24 MPI variant. The distribution of dermotropic L. infantum zymodemes in the Mediterranean area is discussed and the presence of a possible parasite reservoir is suggested.
