Excerpt
The principles and methods of leishmaniasis control are dictated by the need to consider the three links in the parasite system (the causative agentthe leishmania, its invertebrate host-the sanuily, and its vertebrate host-a mammal or man) that are characteristic of any form of leishmaniasis, as it is an obligately vector-borne disease. However, leishmaniasis control varies in different countries as the different forms of leishmaniasis differ substantially from each other in their epidemiology and in particular in the part played by wild and domestic animals in the epidemic process. The economic activities of mankind are of great importance in determining the epidemiological situation in leishmaniasls foci as human activities often hrlng about substantial changes in the natural biocoenoses that correspond to these foc~. Thus, agriculture and the cultivation of new land lead to a certain standardization of the environmental conditions of organisms and certain animal and plant species usually become dominant while other species are eliminated. Among such dominant species may be found the sanaes, which are the vectors of leishmaniae, and the animal reservoirs of leishmaniae, thus giving rise to an increase in the epidemiological risk.
