Abstract

The invention relates to an oligonucleotide sequence combination for specific detection of bordetella pertussis and bordetella parapertussis nucleic acids existing in a sample with the adoption of fluorescent PCR (polymerase chain reaction), and a kit containing the combination. The kit can sensitively detect the bordetella pertussis nucleic acid and the bordetella parapertussis nucleic acid existing in the sample with a detection lower limit of 20 copies in each reaction system, and has important application value in the fields such as disease surveillance and clinical diagnosis.

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...
