Pneumococcal phase variation of 37 middle ear and 31 nasopharyngeal isolates obtained from children with acute otitis media was examined in the absence of intervening culture. The fraction of the opaque colonies was significantly higher in middle ear isolates than in nasopharyngeal isolates. The difference is probably the result of the pneumococci adapting to differential selective environments.
在没有中间培养的情况下,检测了 37 株来自急性中耳炎儿童的中耳分离株和 31 株鼻咽分离株的肺炎球菌相变异。中耳分离株中不透明菌落的比例明显高于鼻咽分离株。这种差异可能是肺炎球菌适应不同选择环境的结果。
