What Is A 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.
