Example Embodiment

[0065] Example 1 Specificity and sensitivity of Plasmodium detection

[0066] 1. Experimental steps

[0067] 1. Collection of blood samples

[0068] Take 1.0ml of the whole blood sample of the patient tested at the port.

[0069] 2. Preliminary identification of blood samples

[0070] The colloidal gold method was used to preliminarily determine whether the patient was infected with Plasmodium.

[0071] 3. Extraction of genomic DNA

[0072] Use blood sample genomic DNA extraction kit (spin column type, Qiagen company) to extract Plasmodium DNA. Take a 50uL whole blood sample and extract DNA according to the extraction steps in the kit instructions.

[0073] 4. Determination of DNA concentration

[0074] The DNA concentration of Plasmodium was quantified by real-time quantitative PCR using ABI's real-time fluorescence detector.

[0075] 5. Amplification of target genes

[0076] 5.1 Design of primers and probes

[0077] Design primers for the unique genes of Plasmodium, and design specific prob...

Abstract

The invention relates to a rapid and high-throughput plasmodium detection method. According to the method disclosed by the invention, two powerful molecular biological technologies of polymerase chain reaction (PCR) and micro-array are integrated, a PCR hybridization probe is directly fixed in a hybridization cabin and arranged on the same chip as a PCR reaction chamber; the detection method comprises the steps of blood sample DNA liquid extraction, PCR amplification, hybridization, washing and result analysis. The rapid and high-throughput plasmodium detection method disclosed by the invention can be used for rapid sensitive detection of falciparum malaria plasmodium, vivax malaria plasmodium and quartan malaria plasmodium, the detection efficiency of front-line inspection and quarantine personnel at import-export ports is greatly improved, not only is the workload reduced but also the problem of positive undetected samples possibly missed according to the conventional detection methods can be solved to the largest extent, and therefore the occurrence of plasmodium epidemic situation is prevented to the largest extent.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnostic reagents, in particular to a rapid and high-throughput detection method for malaria parasites. Background technique [0002] Malaria is one of the most serious global public health problems, and more than half of the world's population lives in malaria-endemic areas. In recent years, imported malaria in my country has been on the rise year by year. There are four species of Plasmodium that infect humans: Plasmodium falciparum (P.f), Plasmodium vivax (P.v), Plasmodium malariae (P.m ) and Plasmodium ovale (P.o). Therefore, effective detection of Plasmodium is an essential means for medical diagnosis and malaria control. At present, microscopic examination is still used as the "gold standard" for diagnosing malaria in my country. Microscopic examination is affected by the subjective judgment and sense of responsibility of microscopic personnel, and it is very easy to miss diagnosis and d...
