A whole year in 2022, while we all talk about nucleic acid testing and pharyngeal swabs, but how much do you really know about pharyngeal swabs?
Clinical significance of pharyngeal swabs.
If pathogenic bacteria are detected in the throat swab secretions, it is considered a respiratory 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 antibiotics should be stopped immediately and replaced with antifungal drugs such as amphotericin B, ashwagandha, clotrimazole, etc.
Common pathogenic bacteria are.
①, gram-positive bacteria: there are Staphylococcus aureus, Streptococcus pneumoniae, β-hemolytic streptococcus, Corynebacterium diphtheriae, Candida, etc.
②, gram-negative bacteria: there are Neisseria meningitidis, Neisseria gonorrhoeae, Haemophilus, Moraxella, Cataplasma boulardii, Mycobacterium pertussis, Enterobacter, Pseudomonas aeruginosa and alkali-producing bacilli, etc. If Mycobacterium tuberculosis is cultured, it is tuberculosis.
③, the corresponding bacteria can be isolated from the pharynx of patients with whooping cough and diphtheria
④, acute pharyngitis and nasal abscesses are mostly caused by Staphylococcus aureus, Streptococcus hemolyticus, and Pseudomonas aeruginosa
⑤, many pharyngeal infections are 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: Fluorescent PCR technique was used to detect Mycoplasma pneumoniae DNA in pharyngeal swabs of children. and correlated with clinical diagnosis. Results: 71 cases of pharyngeal swabs were positive in 100 children with clinical diagnosis of Mycoplasma pneumoniae. Conclusion The technique of pharyngeal swab for detecting Mycoplasma pneumoniae DNA is quick, easy, highly sensitive, and has good compliance in children, and is worthy of clinical promotion and application.
