Leishmaniosis is diagnosed usually by direct visualization of the amastigotes in hosts’ tissues. However, the retrieval of tissue samples is often painful for the patient and identification of the infected cells can be difficult, especially when scanty parasites occur in the examined tissue. Several animals’ species of carnivores were studied. In the search of an alternative diagnostic tool, the bioliquids (sera, urine, saliva) of canids (dogs, red and polar foxes and raccoon dogs) screened by serology, were studied by coproscopy and crystalloscopy (classic and tezigraphy), also. This study also represents the first epizootological study of biosubstrats of dogs in the South of RF, and epidemiological analysis of cases of Leishmaniasis in RF.The development of hunting and tourism, on the one hand, and the increase in the number of domestic carnivores, on the other hand, has lead to the mutual circulation of pathogens between natural and synanthropic foci and, as a result, to an increase in human infections with leishmaniasis pathogens. In this regard, the search for more effective measures of the invasion control is becoming on the agenda. Undoubtedly, the material well-being of the population, demographic and cultural characteristics have a significant impact on the spread of leishmaniasis. At the same time, highly effective, accurate and quick diagnosis of this parasitosis in animals, the organization of veterinary and health measures should be aimed at reliable prevention of anthropozoonosis in the population.
