  Methods for detecting a malaria parasite are described that include: releasing the malaria parasite by allowing an erythrocyte in a specimen to undergo hemolysis in two steps by means of a first and a second hemolytic agents comprising surfactants; staining the released malaria parasite with a fluorescent dye to prepare a measurement sample; detecting optical information from the measurement sample; and distinguishing the malaria parasite based on the optical information obtained. The optical information is preferably fluorescent intensity and scattering light intensity, and is eventually obtained with the aid of a flow cytometer. The apparatus and the reagent kits for carrying out the invention are also described.

  A method of staining bacteria comprises: working a polymethine dye on a sample in the presence of a substance capable of reducing nitrite ions to stain bacteria in the sample. A method of detecting bacteria comprises the following steps of: (1) working a polymethine dye on a sample by a method as described above to stain bacteria in the sample, (2) introducing the thus treated sample into a detecting part of a flow cytometer and irradiating cells of the stained bacteria one by one with light to measure scattered light and fluorescent light emitted from each of the cells; and (3) discriminating the bacteria from other components in accordance with an intensity of a scattered light signal and an intensity of a fluorescent light signal or a pulse width reflecting the length of particles to count the bacteria.
