Throat swab
Normal people’s pharyngeal isthmus culture should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur due to the decline of the body's systemic or local resistance and other external factors, which can lead to diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, and acute pharyngitis.
If pathogenic bacteria are detected in the secretions of the throat swab, it is regarded as a respiratory infection. It can be combined with other tests (X-ray fluoroscopy, B-ultrasound, etc.) to diagnose the respiratory tract infection. If yeast-like bacteria are cultivated, consider whether to use antibiotics improperly or excessively during the infection period. The use of antibiotics should be stopped immediately and antifungal drugs, such as amphotericin B, griseofulvin, clotrimazole, etc. should be used.

Throat swab principle
Because breathing and food pass through the mouth, all kinds of bacteria will be parasitic in the mouth. Such as catarrhalis, various staphylococci, various streptococci, diphtheria-like bacilli, Klebsiella pneumoniae and Escherichia coli. There are also anaerobic bacteria, such as peptococcus, Bacteroides and yeast-like bacteria.
Influenza is spread through the respiratory tract, and the pharynx is where such viruses gather. The throat swab specimen is a medical cotton swab, and a small amount of secretions are dipped from the human pharynx. The sample taken is a throat swab specimen. In order to detect the type of respiratory disease virus, the throat swab can often be used to quickly and accurately detect the Type of virus.
