作者调查囊性纤维变性(简称CF)病人口腔内不同部位上绿脓杆菌的出现率、分布情况和抗菌素对此菌的敏感试验。材料和方法;任选年龄、性别相似的31例CF患者和31名未患CF者,分作两组。均以舌背、颊粘膜、牙菌斑、唾液中,取标本作绿脓杆菌检查,痰的标本只从CF病人中取得。把取到的标本一式二份地接种在cetrimide平板、血平板和McConkey平板上,在37℃有氧环境下孵化。24、48、72小时后,检查生长情况和菌落形态。做革兰氏染色和生化试验。结果发现,31位CF患者中,14人至少在
The authors investigated the incidence and distribution of Pseudomonas aeruginosa in different parts of the oral cavity of patients with cystic fibrosis (CF) and the antibiotic susceptibility test. MATERIALS AND METHODS: Thirty-one CF patients and 31 non-CF patients of similar age and gender were divided into two groups. All tongue, buccal mucosa, plaque, saliva, specimens taken for Pseudomonas aeruginosa examination, sputum specimens obtained from CF patients only. The obtained specimens were inoculated in duplicate on cetrimide plates, blood plates and McConkey plates and incubated under aerobic conditions at 37 ° C. 24, 48, 72 hours later, check the growth and colony morphology. Do Gram staining and biochemical tests. The results showed that, in 31 CF patients, 14 at least
