Résumé
Objective:To establish a specific and sensitive method using loop-mediated isothermal amplification for rapid screening of Salmonella. Methods:The invA gene sequence of Salmonella was downloaded from GenBank. After homology comparison with DNAMAN software， amplification primers were designed in the conserved region， and a LAMP-LFD detection method was established. The reaction system was optimized， and the specificity and sensitivity of the method were verified. Results:The sensitivity of this method to detect Salmonella DNA was up to 1.0×101 copies/μL. The positive rate of anal swabs was the same as that of fluorescent PCR. Meanwhile， LAMP-LFD was easy to operate and did not need expensive instruments. The detection result could be obtained within 30 minutes. Conclusion:The LAMP-LFD method established in this study is rapid， simple， sensitive and specific， which is suitable for rapid screening of Salmonella.
Résumé
Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development
