  • Patent number: 5124141
    Abstract: A diagnostic method for the detection of human malaria infections. Specifically, blood samples are combined with a reagent containing 3-acetyl pyridine adenine dinucleotide (APAD), a substrate (e.g. a lactate salt or lactic acid), and a buffer. The reagent is designed to detect the presence of a unique glycolytic enzyme produced by the malaria parasite. This enzyme is known as parasite lactic acid dehydrogenase (PLDH). PLDH is readily distinguishable from host LDH using the foregoing reagent. Combination of the reagent with a parasitized blood sample results in the reduction of APAD. However, APAD is not reduced by host LDH. The reduced APAD may then be detected by various techniques, including spectral, fluorimetric, electrophoretic, or colorimetric analysis. Detection of the reduced APAD in the foregoing manner provides a positive indication of malaria infection.
