Many people may know what a pharyngeal swab is, but not much is known about this pharyngeal swab, so let's learn more about it!
Clinical significance
If pathogenic bacteria are detected in the throat swab secretions, it is considered a respiratory tract infection. It can be combined with other tests (X-ray fluoroscopy, ultrasound, etc.) to diagnose the site of respiratory tract infection. If yeast-like organisms are cultured then consider whether antibiotics were used inappropriately or in excess during the infection and should be stopped immediately and replaced with antifungal drugs such as amphotericin B, ashwagandha, clotrimazole, etc.
The common pathogenic bacteria are.
1. Gram-positive bacteria: Staphylococcus aureus, Streptococcus pneumoniae, β-hemolytic streptococcus, Corynebacterium diphtheriae, Candida, etc.
Gram-negative bacteria: Neisseria meningitidis, Neisseria gonorrhoeae, Haemophilus, Moraxella catarrhalis, Mycobacterium pertussis, Enterobacter aeruginosa, Pseudomonas aeruginosa and Mycobacterium alkaloids, etc. If Mycobacterium tuberculosis is cultured, it is tuberculosis.
3. Pertussis The corresponding bacteria can be isolated from the pharynx of patients with diphtheria
4. Acute pharyngitis and nasal abscesses are mostly caused by Staphylococcus aureus Streptococcus hemolyticus Pseudomonas aeruginosa
5. Pharyngeal infections are mostly caused by anaerobic bacteria
Clinical analysis
Objective To investigate the clinical value of pharyngeal swabs for detection of Mycoplasma pneumoniae DNA in pediatric patients with respiratory Mycoplasma pneumoniae infection. Methods A fluorescent PCR technique was used to detect Mycoplasma pneumoniae DNA in the pharyngeal swabs of children, and correlated with clinical diagnosis. The results showed that the pharyngeal swabs of 100 children with clinical diagnosis of Mycoplasma pneumoniae were positive in 71 cases (71%). Conclusion The technique of pharyngeal swab for detecting Mycoplasma pneumoniae DNA is quick, easy, sensitive, and good for children's compliance, and is worthy of clinical application.
Precautions
1. During the operation, care should be taken to disinfect the bottle and keep the container sterile.
2. It is best to collect specimens before treatment with antibacterial drugs.
