Diagnostic des parasitoses à parasites sanguicoles

The technics include the direct examination to identify the extra cellular parasites, which are mobile among the blood red cells, or thin and thick smear, after coloration. It is often useful to use other technics, such as filtration, culture or animal inoculation. Recently, the molecular biology increased the sensitivity and the specificity of classical methods. Such progress, available by some laboratories, must be adapted to the methods of emergency and low cost diagnosis. In some cases of pauciparasitism or retrospective diagnosis, serological methods are useful to detect the trail of parasites by circulating antigens or antibodies.
