摘要
据既往资料,医院环境细菌学监测中没有开展细菌L型的分离工作,亦少有关于分离到细菌L型的报道。我们于1990年6月在对省医院环境进行细菌学监测中除分离出20株不同种细菌外,还分离到4株细菌L型。经12～16次传代反应基本回复。回复菌分别签定为绿脓杆菌、洋葱假单胞菌、摩根摩氏菌和卡他布兰汉氏菌。医院环境中分离出细菌L型说明医院环境中存在着可使细菌转变为L型的诱导因素。而细菌L型的存在可能是引起医院感染的一个危险因素。
In June 1990 we isolated 24 strains of differ-
ent species of bacteria, including 4 strains of
L-form bacteria. After 12-16 passages, all
L-form bacteria retured to normal in their
biochemical reaction. The recovery bacteria were
identified as Pseudomonas pyocyaneas,
Pseudomonas cepacia, Morg morgani and B.
catarrhalis. The existence of L-form bacteria in
hospital environment indicated that there might
be a inducing factors which can make the
bac-teria transform into L-form. It is Difficult for
L-form to return to normal, because of the
per-manent of the inducing factors and their ex-
istence and action on the bacterial cell wall. It
was thought that the existence of L-form might
be a risk factor in causing hospital ac-quired in-
fections.
