Throat swab
Normal human 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 are not pathogenic under normal circumstances, but infections can occur when the body's systemic or local resistance declines and other external factors lead to diseases. Therefore, bacterial culture of throat swab can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, acute pharyngitis, etc.
Pathogenic bacteria detected in throat swab secretions are considered respiratory infections. It can be combined with other examinations (X-ray fluoroscopy, B-ultrasound, etc.) to diagnose the site of respiratory infection. If yeast-like bacteria are cultured, consider whether antibiotics are used inappropriately or excessively during infection. Antibiotics should be stopped immediately and antifungal drugs, such as amphotericin B, griseofulvin, and clotrimazole, should be used instead.
Pharyngeal swab principle
Because both breath and food pass through the mouth, bacteria of all kinds live in the mouth. Such as catarrhal bacteria, various Staphylococcus, various Streptococcus, Diphtheria-like bacteria, Klebsiella pneumoniae and Escherichia coli. In addition, there are anaerobic bacteria, such as Peptococcus, Bacteroidetes and yeast-like bacteria.
Influenza is spread through the respiratory tract, and the pharynx is where the virus gathers. Throat swab specimens are medical cotton swabs, which are dipped in a small amount of secretions from the pharynx of the human body, and the samples taken are throat swab specimens. Virus type.
