摘要

Dogs are the major reservoir ofLeishmania infantum, the causative agent of human and canine visceral leishmaniasis in the Mediterranean basin. In Morocco, canine leishmaniasis (CanL) is usually believed to be widespread mainly, if not only, in the northern regions and few data are available about the situation in southern parts of the country. Here, we report the results of a preliminary, clinical, and serological study carried out in 2004–2007, in four provinces of southern Morocco. Serological analyses were processed using two different Elisa techniques, a homemade Elisa test and IDVET commercial kit, and confirmed by two different western blot (WB) tests, homemade and LDBIO commercial kits. We highlighted the presence of CanL infection in southern regions, known until then as free of the disease: 19.8% (48/243) of examined dogs displayed clinical signs compatible with CanL and the seroprevalence was particularly high, respectively, 81.8% and 87.8% by Elisa and western blot tests. Our current developed and validated homemade (Elisa and WB) tools will be cost-effective and useful for next large-scale epidemiological studies on Moroccan leishmaniasis animal reservoir.
