摘要
冬季是呼吸道反复感染的多发季节。我们对反复发生呼吸道感染病人口咽粘膜菌群的定植进行了分析。结果表明，正常组需氧菌群密度为４．１１３５±０．０８８４，厌氧菌群密度为４．４１０１±０．３５８６１；患者需氧菌群密度为４．５２９０±０．００８６，厌氧菌群密度为４．８７１８±０．３４２４。反复呼吸道感染患者需氧菌和厌氧菌的含量均不于正常对照组（Ｐ＜０．０５）。１８例病人分离出两种以上需氧菌，奈瑟氏菌和肺炎链球菌检出率较高，分别为３８．７％和２２．６％；厌氧菌以韦荣氏球菌和消化链球菌为多见，检出率分别为３２．２％和５８．１％。有７例病人分离出白色念珠菌。４例病人分离出绿脓杆菌，明显表现出微生态失调。药敏结果表明，不同菌株对抗生素均有一定的耐药性存在。
Localization of bacterium mass in oral mucosa of the petients with recurrent respiratory infection was analyzed in the paper. The results showed that the densities of aerobes and snser- obes were 4. ll35±0. 0884 and 4. 4101 ± 0. 3586 respectively in normal subjects, whereas they were 4.5290±0.0086 and 4. 8718±0. 3424 respectively in the patients. The contents of aerobes and anaerobes were higher in the patients than in the control(p< 0. 05 ) . More than two kinds of aerobes were isolated from 18 cases of the patients, from which the detecting rates of Neisseria and peptostreptococcus were in the mojority in anaerobes and their detecting rates were 32. 2 percent and 58. I percent respectively. Candida albicantia were isolated from 7 cases of the pationts and pseudomonas aeruginosae from 4. lt was indicated that microecological imbalance had occurred in the patients with recurrent respiratory infections. Drug sensitivity test revealed the tolerance of defferent bacteria to antibiotics.
