Geographical Distribution and New Situation of Leishmania Species after the Control of Cutaneous Leishmaniasis Foci in Errachidia Province, Morocco, in 2014

الملخص EN

In Errachidia province, the incidence of cutaneous leishmaniasis (CL) has increased over the past decade and it was higher in 2010 (860.34 per 100,000 inhabitants), with 3445 cases.

The number of cases declined sharply and decreased from 3445 cases in 2010 to 8 cases in 2014 following the control action plan interventions.

The total of patients was diagnosed only on clinical basis and the lesions were considered caused by L.

major.

The epidemiological study was conducted between 2001 and 2014 and the molecular detection of CL was studied to identify the circulating parasite species in this province by using the ITS1-PCR-RFLP methods.

In 2010, the molecular identification of 11 samples revealed the presence of L.

major in the most affected circles: Goulmima, Er-Rissani, and Errachidia.

In 2014 the molecular characterization of 7 among 8 cases reported in this year showed the presence of L.

tropica in Errachidia circle.

This is the first molecular identification of L.

tropica in Errachidia province.

The detection of this species after the intensified control measures strategies suggests that it was probably dissipated through the dominance of L.
