Embodiment Construction

[0030] Use bacterial positive control as a sample. The kit is composed of primer probe mixed solution, RT-PCR Buffer, mixed enzyme, yang-PCR, and no RNase water; RT-PCR Buffer includes PCR buffer, DATP, DUTP, DCTP, DGTP, and MGCL 2 The mixed enzyme solution includes a HOT START TAQ enzyme, inverse transcriptase, and UNG enzymes; a plasmid containing the amplified gene sequence corresponding to the digestive pathogens in the yang nature control.

[0031] The primer in the amplification system was 100-1000 nm; the final concentration of the probe was 50-500 nm in the amplification system.

[0032] The reactant system of the kit is 30 μL, specifically: a nucleic acid template 7 μL, RT-PCR Buffer 20 μL, 1 μl of mixed enzyme solution and 2 μl of the primer probe mixture.

[0033] Operation and results of the kit

[0034] (1) Extract the sample DNA to the template (extracted from the child's feces), no RNase water, and 7 μL of the yang-nature control each additionally PCR reaction tube,...

Abstract

The invention relates to a primer group, a probe group and a kit containing the primer group and the probe group, which are used for synchronously detecting various common digestive tract infection related bacteria of children and can be used for simultaneously detecting various common bacteria causing digestive system infection by one-time reaction. The kit is the most comprehensive children digestive tract bacterial infection detection method at present, is high in efficiency and specificity, and provides an auxiliary diagnosis basis for clinical examination. According to the technical scheme, the technical problem that in the prior art, diagnosis and research on bacterial pathogenic bacteria related to children digestive tract infection are still insufficient can be solved.

Description

Technical field [0001] The invention belongs to the field of pathogenic microbial molecular biology, and in particular to primer probe combinations and kits for detection and distinguishing between children with different bacterial pathogens in children with differential tract infections. Background technique [0002] Digestive tract infection is a common disease. It is especially more common in clinical pediatrics. The incidence rate has increased year by year, second only to respiratory system infection, the second largest number of transients, multi-cause bacteria, viruses, fungi or parasite, etc. Pathogenic bacteria infection leads. The annual average canopy, common in bacteria is the jejuno curved bacteria (CJE), CDIFF (CDIFF), murine injury (STYP), vialoxicuris (VP), small intestinal colitis Yerssen ( YENT), adhesive Escherichia coli (EAEC), ETEC, pathogenic large intestine EPEC, hemorrhagic large intestine EEHCE (EEC), invasive large intestine Epsi (EEC), Chikiochemistry (...
