4 results about "Campylobacter coli" patented technology

This invention discloses an sgRNA and RPA primer pair and their application in the detection of Campylobacter coli, wherein the sgRNA contains a target sequence with a nucleotide sequence as shown in SEQ ID NO.1 or SEQ ID NO.2. The detection method of this invention has a limit of detection of 10. 0 With a concentration of CFU / mL, it exhibits high specificity, simple detection operation, and is not limited by site, equipment, or operator expertise. It has a wide range of applications and can be used for rapid detection of Campylobacter coli in actual fecal samples, with accurate results.

The invention discloses a primer composition for detecting pathogenic campylobacter based on a loop-mediated isothermal amplification technology and a detection method, and belongs to the technical field of biological detection of pathogenic bacteria. The detection method provided by the invention can quickly and accurately detect whether a sample to be detected contains pathogenic campylobacter jejuni and campylobacter colons or not, specifically, detection can be completed within 20 minutes, a detection result can be read, and the detection time is obviously shorter than that of a real-time fluorescent quantitative PCR method which is commonly adopted at present; the method has important application value in public health, food safety, animal husbandry and veterinary medicine and entry and exit inspection and quarantine.

The present invention discloses a primer combination and detection method for detecting pathogenic Campylobacter based on loop-mediated isothermal amplification technology, belonging to the field of biological detection technology for pathogenic bacteria. The detection method provided by the present invention can quickly and accurately detect whether a sample contains pathogenic Campylobacter jejuni and Campylobacter coli. Specifically, the detection and reading of the test results can be completed within 20 minutes, which is significantly shorter than the currently commonly used real-time fluorescence quantitative PCR method. It has important application value in public health, food safety, animal husbandry and veterinary medicine, and entry-exit inspection and quarantine.
