The invention belongs to the field of biomedical treatment, and particularly relates to a convection amplification primer group, a probe and a kit for multiple detection of lower respiratory pathogens. The convection amplification primer pair comprises a legionella pneumophila primer pair, an adenovirus primer pair and a chlamydia psittaci primer pair, primer sequences in the legionella pneumophila primer pair, the adenovirus primer pair and the chlamydia psittaci primer pair respectively comprise a target nucleic acid complementary sequence and an interface sequence, and the interface sequence is located at the 5'end of the target nucleic acid sequence; the nucleic acid is not complementary with the target nucleic acid; the target nucleic acid complementary sequence has a folded sequence, and the folded sequence is complementary to the interface sequence, so that the primer sequence has a bent hairpin structure. Meanwhile, a primer probe is designed, and a respiratory tract pathogenic bacteria multiple detection kit is prepared. The multiple detection can avoid non-specific amplification and improve the detection sensitivity.

The application belongs to the field of biological medicine, and particularly relates to a multiplex detection lower respiratory tract pathogen counterflow amplification primer set, probe and kit. The counterflow amplification primer set comprises a Legionella pneumophila primer pair, an adenovirus primer pair and a Chlamydophila psittaci primer pair. The primer sequences in the Legionella pneumophila primer pair, the adenovirus primer pair and the Chlamydophila psittaci primer pair each comprise a target nucleic acid complementary sequence and an interface sequence. The interface sequence is located at the 5' end of the target nucleic acid sequence and is not complementary to the target nucleic acid. The target nucleic acid complementary sequence has a folding sequence, and the folding sequence is complementary to the interface sequence, so that the primer sequence has a curved hairpin structure. A primer probe is designed, and a respiratory tract pathogenic bacteria multiplex detection kit is prepared. The multiplex detection can avoid non-specific amplification and improve the detection sensitivity.
