The invention discloses an immunity-chromatography kit for the rapid diagnosis of malaria and its pathogen species and a preparation method thereof. The kit comprises a colloidal gold immunity-chromatography test strip, a matching cell-free lysate, a sample cup, a blood taking needle, and an operating instruction. The colloidal gold immunity-chromatography test strip comprises a sample pad, a colloidal-gold pad, a cellulose membrane, and a water-absorbing pad, wherein the colloidal-gold pad contains colloidal gold labelled antibodies; a detection line and a quality control line are disposed on the cellulose membrane; and the colloidal gold labelled antibody and the detection line are composed of monoclonal antibodies which can specifically bind the lactate dehydrogenase of plasmodia. The immunity-chromatography kit for the rapid diagnosis of malaria and its pathogen of the invention can distinguish falciparum malaria from vivax malaria, has the advantages of simplicity, sensitivity, specificity, and rapidity, and is suitable for clinical and field applications.

The present invention provides nucleic acid aptamers that bind to Plasmodium proteins lactate dehydrogenase and histidine-rich protein II, and uses thereof for the diagnosis of malaria. Aptamers against histidine-rich protein II may be used to detect the presence of Plasmodium species in general, whereas aptamers against lactate dehydrogenase can be used to specifically detect Plasmodium falciparum.

Disclosed herein are a DNA aptamer specifically binding to pLDH (Plasmodium Lactate Dehydrogenase), a composition for the diagnosis of malaria, comprising the same, and a diagnostic kit for malaria using the same. Superior in specificity and stability to antibodies which are conventionally used to diagnose malaria, the DNA aptamers specifically binding to pLDH (Plasmodium Lactate Dehydrogenase) in accordance with the present invention can be developed into biosensors which determine pLDH levels with high sensitivity and accuracy, greatly contributing to the diagnostic accuracy of malaria.

The invention discloses a test strip for rapidly detecting plasmodia based on colloidal gold immunochromatographic assay, as well as antibodies and cell lines thereof. The test strip comprises a basal plate, a sample pad, a polyester cellulose pad, a nitrocellulose membrane and a water absorbent pad, wherein the sample pad, the polyester cellulose pad, the nitrocellulose membrane and the water absorbent pad are partially superposed in sequence along the length direction of the basal plate and fixed on the basal plate; a colloidal gold-antibody I (H12) conjugate coating is sprayed on the polyester cellulose pad; a first test line, a second test line and a quality control line are distributed on the nitrocellulose membrane; the first test line is formed by performing spray-coating on an antibody II (A5) on the nitrocellulose membrane; the second test line is formed by performing spray-coating on an antibody IV (F6) on the nitrocellulose membrane; and the quality control line is formed by performing spray-coating on an goat anti-mouse IgG1 antibody on the nitrocellulose membrane. The test strip provided by the invention is easy to operate, rapid, sensitive and specific, and is applied to the rapid and early-stage diagnosis of malaria.

The detection of PfHRP II in saliva offers a practical, cost-effective alternative to PfHRP II detection in blood as a means for diagnosis of malaria. Collection of saliva is non-invasive, simple, safe, stress free, painless and can be accomplished in primitive settings.
