Abstract
A method of treating a body fluid so as to inactivate protozoa in said fluid comprises mixing the body fluid with an effective amount of a photosensitizing agent which will bind to cell-free protozoa and/or protozoan-infected cells, and then exposing the resulting mixture to visible light to inactivate the protozoa. An apparatus for use in the method includes at least one container which contains a body fluid containing protozoa and an effective amount of a photosensitizing agent to bind to the protozoa. The apparatus has at least one wall which is permeable to visible light.
