Methods for Leishmania parasite detection and quantificatio as a tool for study of the pathogen-vector-host interactions

Methods for Leishmania parasite detection and quantification as a tool for study of the pathogen-vector-host interactions Leishmaniasis in human is caused by total 21 species of the intracellular protozoan parasite Leishmania, which are transmitted by about 30 species of phlebotomine sand flies. Besides human, Leishmania can infect a number of vertebrate hosts. The major host cell is the macrophage, in which parasites multiply, eventually rupturing the cell and spreading to uninfected cells. Infected monocytes and macrophages circulating in the peripheral blood are thought to be carriers of the parasite to distal sites. Depending on the infected sites of the body, there are three forms of leishmaniasis: cutaneous, mucocutaneous and visceral. Leishmaniasis is a disease for which we still lack effective, affordable and easy to use drugs. In addition, surveillance and control are also neglected. This thesis summarizes the results of several projects using different approaches for parasite load measurement in the mouse model of leishmaniasis, including two methods that were developed and optimized in our laboratory. Detection and quantification of pathogens belongs to the major topics of the research of various infectious diseases. This parameter is necessary for confirmation of the diagnosis, characterization..
