近来一些研究发现,流感嗜血杆菌和肺炎链球菌是引起急性中耳炎的主要细菌,在儿童伴有渗液的慢性中耳炎的无菌中耳渗液中发现有内毒素和肺炎链球菌荚膜多糖。提示急性中耳炎转为慢性中耳炎的发病机制和某些细菌细胞成份有关。为弄清这个问题,作者作了以下实验。首先用灭活的同型不同株的二株肺炎链球菌的悬液分别在二组堵塞咽鼓管产生中耳渗液的灰鼠中耳内接种,其中一组为荚膜菌,另
Recently, some studies have found that Haemophilus influenzae and Streptococcus pneumoniae are the major bacteria causing acute otitis media. Endotoxin and Streptococcus pneumoniae capsular polysaccharide are found in the sterile middle ear effusion of children with chronic otitis media with exudate. Tip acute otitis media into chronic otitis media pathogenesis and some bacterial cell components. To clarify this issue, the author made the following experiment. First, inoculation of two strains of Streptococcus pneumoniae suspension of inactivated homoplasia different strains were respectively inoculated into the middle ear of squirrels with occult eustachian tube producing middle ear effusion. One group was capsular bacteria,
