Abstract

The invention discloses a detection method for EV71 virus in an environmental water body, wherein a semi-nested RT-PCR (Reverse Transcription-Polymerase Chain Reaction) and real-time fluorescence quantification RT-PCR reaction system is established to detect EV71 virus in the environmental water body by using a recombinant plasmid as a reference product, and the recombinant plasmid is prepared by using a primer and a probe aiming at EV71 virus designed according to a genetic conservative fragment of enterovirus belonging to a VP1 serotype area. The method has good specificity and high sensitivity and precision, and can qualitatively and quantitatively detect EV71 virus in the environmental water body accurately.

Description

technical field

[0001] The invention belongs to the technical field of detection of environmental water quality, and in particular relates to a detection method of EV71 virus in environmental water. technical background

[0002] Enterovirus 71 (EV71) belongs to the Enterovirus genus and has attracted much attention in recent years. It is a major pathogen that causes hand, foot and mouth disease. EV71 is a water-borne virus that can be leaked from the secretions of EV71-infected patients into environmental water bodies and can survive in environmental water bodies for a long time. The water body polluted by it becomes an important pollution source of EV71, which can cause the outbreak of hand, foot and mouth disease.

[0003] Existing methods for detecting EV71 mainly include cell culture method and polymerase chain reaction (Polymerase Chain Reaction, PCR). There are a variety of pathogenic microorganisms in environmental water, especially other enteroviruses. These microo...
