Problems solved by technology

[0003] The traditional Klebsiella pneumoniae detection method is far from meeting the requirements of modern detection due to its shortcomings such as long detection cycle, complicated procedures, and various reagents required.
The pathogenic nucleic acid detection technology represented by polymerase chain reaction (PCR) technology has some problems in practical application, such as ordinary polymerase chain reaction (PCR) technology requires special equipment, and there are easy cross-contamination and cumbersome operation process Shortcomings
Although the fluorescent real-time quantitative polymerase chain reaction (real time P...

Abstract

The invention provides a klebsiella pneumoniae detection kit. The klebsiella pneumoniae detection kit comprises two pairs of primers, i.e., an inner primer FIP/BIP and an outer primer F3/B3, which use oppA gene of klebsiella pneumoniae as the target gene and is designed based on the loop-mediated constant-temperature amplification technology. The klebsiella pneumoniae detection kit has more comprehensive detection effect and low omission ratio.

Description

technical field [0001] The invention relates to a biological detection reagent, in particular to a detection kit for Klebsiella pneumoniae and a use method thereof. Background technique [0002] Klebsiella pneumoniae, belonging to the family Enterobacteriaceae, is a Gram-negative bacillus that does not require high nutrition and can grow on ordinary agar medium. The optimum growth temperature is 37°C. Klebsiella pneumoniae is highly pathogenic to humans and is one of the important opportunistic pathogens and iatrogenic infections. Klebsiella pneumoniae is widely distributed in nature such as soil, water, agricultural products and forest products , It is also common in the intestinal tract and respiratory tract of humans and animals. Food contaminated by Klebsiella pneumoniae has no difference in appearance and taste from normal food, so accurate and rapid detection of Klebsiella pneumoniae is of great significance. [0003] The traditional Klebsiella pneumoniae detection m...
