The present invention provides an in vitro method for concentrating infectious pathogens found in a biological sample obtained from an individual who is suspected of being infected with the pathogens. Provided herein is also an in vitro method for reducing or eliminating blood cells from a sample obtained from an individual suspected to being infected with an infectious pathogen. The present invention also provides a method for diagnosing malaria and a method for determining if an individual is infected with a pathogen. Provided herein is also a concentrator and a kit for use with the methods.

This invention relates to a method for the direct detection of tick-borne infections, wherein the human/animal body fluid sample, ideally blood sample to be examined is obtained directly on a specified amount of cell technology medium establishing a partially hostile (semi-hostile) environment, the sample and the cell technology medium are mixed, incubated and stored, if required, meanwhile, the cells and pathogens of the subject are in the semi-hostile environment, then corpuscles and pathogens are separated; a small amount of blood cells from the buffy coat layer and blood cells located a few cell layers beneath it are supplemented to and mixed with the gained plasma, the sample is concentrated and the test is finally performed to detect pathogens in the plasma and in blood cells. The claimed matter covers cell technology medium applied and its application interesting methods.
