Our nucleic acid detection is in the nasopharynx or oropharynx, because the culture of normal pharyngeal isthmus is normal oral flora, there is no growth of pathogenic bacteria. The bacteria in the pharynx are from the outside world and will not cause disease under normal circumstances. However, due to the decline of systemic and local resistance and other external factors, it may cause infection and other diseases. Therefore, bacterial culture of pharyngeal swab can isolate pathogens. Pharyngeal swab culture specimens were collected before antibiotic treatment. Throat is the channel for breathing and food. It's best to start collecting in the morning. Do not gargle or apply disinfectant to the lesion several hours before sampling. Avoid contact with mouth, tongue mucosa and saliva. Tonsillar fossa is the best site for tonsillar specimens.
