Problems solved by technology

Pathogen culture is the gold standard for pertussis detection. It has strong specificity, but its sensitivity is poor. At the same time, it has the disadvantage of taking a long time and is not suitable for rapid detection in laboratories.
Serological detection of specific Bordetella pertussis and Bordetella parapertussis antibodies often requires double blood, and the detection sensitivity is low. It is mainly used for retrospective diagnosis or auxiliary diagnosis of atypical cases
[0005] The incidence of whooping cough may be underestimated due to the lack of specific laboratory tests and case diagnosis based on clinical symptoms

Abstract

The invention relates to an oligonucleotide sequence combination for specifically detecting the presence of Bordetella pertussis and Bordetella parapertussis nucleic acids in a sample by using fluorescent PCR technology, and a kit comprising the combination. The kit can sensitively detect and identify the Bordetella pertussis nucleic acid and Bordetella parapertussis nucleic acid present in the sample, and the lower limit of detection is 20 copies per reaction system. It has great potential in disease monitoring, clinical diagnosis and other fields. important application value.

Description

Technical field [0001] The invention relates to an oligonucleotide sequence combination for specifically detecting the presence of Bordetella pertussis and Bordetella parapertussis nucleic acids in a sample by using a fluorescent PCR technology, and a kit comprising the combination. technical background [0002] Whooping cough is an acute respiratory infection caused by Bordetella pertussis. Its clinical features are paroxysmal spasmodic cough accompanied by a deep "cock crow"-like inspiratory roar. If it is not treated promptly and effectively, the course of the disease can reach several months. The disease is very contagious. The younger the child is, the more severe the condition, and death due to concurrent pneumonia and encephalopathy. [0003] Patients with whooping cough is the only source of infection. They are infectious from 1 to 2 days at the end of the incubation period to 6 weeks after the onset of illness, with the most infectious in the first 1 to 3 weeks. When a p...
