Kit for quickly detecting 15 pneumonia pathogenic bacteria

Abstract

The invention discloses a kit for quickly detecting 15 pneumonia pathogenic bacteria. The kit can detect streptococcus pneumoniae, staphylococcus aureus, haemophilus influenzae, mycoplasma pneumoniae, pseudomonas aeruginosa, baumanii, enterococcus faecalis, enterococcus faecium, klebsiella pneumoniae, escherichia coli, enterobacter cloacae, stenotrophomonas maltophilia, burkholderia cepacia, legionella pneumophila and chlamydia pneumoniae which cover clinically common pneumonia pathogenic bacteria difficult to culture. 16S rDNA and specific gene sequences corresponding to the pneumonia pathogenic bacteria are detected by combining gene chips with multiple asymmetric PCR reactions, and the categories of the bacteria in a to-be-detected sample are identified in genus and species. The kit makes up for the defect that current clinical detection of pneumonia pathogenic bacteria is not in time or comprehensive and a novel detection means for early diagnosis and early treatment of patients suffering from pneumonia is provided.

Description

technical field [0001] The invention relates to gene technology, in particular to a kit for rapid detection of 15 kinds of pneumonia pathogenic bacteria. Background technique [0002] In recent years, due to the aggravation of air pollution and the occurrence of public health events, respiratory diseases have attracted more and more attention. Pneumonia refers to the inflammation of lung parenchyma including terminal airways, alveoli and interstitium, and is the leading cause of death from infectious diseases worldwide [1] . According to the statistics of the World Health Organization (WHO), about 3.5 million people die from lower respiratory tract infection every year, ranking third among all causes of death. [2] . In the United States, pneumonia and influenza rank ninth among all causes of death, with more than 50,000 deaths from pneumonia in both 2010 and 2011 [3- 5] , and the statistics did not include sepsis caused by pneumonia and cancer and Parkinson's cases that ...

Problems solved by technology

The detection of bacterial serological antibodies is a rapid detection method, but different antibodies are produced at different times. For example, Mycoplasma pneumoniae IgM antibodies are produced about 2 weeks after the onset of the disease, which cannot meet the needs of rapid clinical diagnosis, and the sensitivity and specificity Unsatisfactory

Infectious Diseases Society of America (IDSA) guidelines once recommended giving antibiotics to patients with lung infections within 8 hours, which was shortened to 4 hours in 2003 [19,20] , it can be seen that the culture, isolation and identification of bacteria is far from meeting the needs of clinical rapid diagnosis, and the early treatment of pneumonia can only rely on empirical treatment, which further aggravates the emergence of drug-resistant strains. Therefore, an accurate and rapid detection method is urgently needed clinically. Pneumonia Pathogen Method
