The typing results of Haemophilus influenzae strains (part of strains). The amplification product of the standard strain (+) contains the bexA gene, which is detected at 343 bp with a clear band. No target band is detected in most of the other strains, including sample No. 8, which is one of the positive samples. 1 and 2 are isolated strains from the nasopharynx of healthy children, 3, 4, and 5 are isolated strains from the sputum of children with lung infection, 6, 7, and 8 are isolated strains from the bronchoalveolar lavage fluid of children with acute lung infection, and M is a DNA marker
