What Is a Nasal Swab?
Normal people have no bacteria in the middle ears and sinuses, that is, no bacteria can be cultured. Oropharyngeal culture should have normal oral flora and no pathogenic bacteria.
- Bacteria in the ears, nose, and pharynx come from the outside world and do not cause disease under normal circumstances. However, the disease can be caused by infection or other factors caused by the decline of the body's overall or local resistance and other external factors. Therefore, ear, nose, and throat swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of otitis media, rhinitis, sinusitis, diphtheria, suppurative tonsillitis, and acute laryngitis. The specimen was collected by the doctor using a sterile cotton swab and the secretion from the patient's lesion was submitted for examination.

Ear, nose, and throat swabs
- Normal people have no bacteria in the middle ears and sinuses, that is, no bacteria can be cultured. Oropharyngeal culture should have normal oral flora and no pathogenic bacteria.
Clinical significance of ear, nose, and throat swab bacteria culture
- For clear diagnosis of pathogens of ear, nose, and throat infections. Common pathogenic bacteria are: (1) Gram-positive bacteria: Staphylococcus aureus, Streptococcus pneumoniae, -hemolytic streptococcus, Corynebacterium diphtheria, Candida, etc. (2) Gram-negative bacteria: Neisseria meningitidis, Neisseria gonorrhoeae, Haemophilus, Moraxella, Brannerella catarrhalis, Pertussis, Enterobacter, Pseudomonas aeruginosa and Alkali Bacillus and so on. (3) The corresponding bacteria can be isolated from the pharynx of pertussis and diphtheria patients. (4) Acute pharyngitis, nasal abscess, and sinusitis are mostly caused by Staphylococcus aureus, hemolytic streptococcus, and Pseudomonas aeruginosa. (5) Many ear, nose and throat infections are caused by anaerobic bacteria.
Precautions for bacterial culture of ear, nose, and throat swabs
- (1) When collecting specimens, try to avoid normal colonization by bacterial contamination. You can wipe the surface with a sterile cotton swab on the affected part before taking the specimen. If there is a pseudomembrane, peel off the pseudomembrane with sterilized tweezers for examination, and if there is an abscess, extract the pus for examination. (2) According to the requirements of aseptic operation, put the test tube mouth on the flame of an alcohol lamp for disinfection, then insert the swab into the test tube, plug the tampon and send it for inspection.
