从事临床细菌检验工作的人员手指,出现了与来自标本所分离的同一菌种所引起的污染。约3%的标本可污染容器外侧。此外,尿及痰的20～40%潜血阳性。血培养瓶几乎十分之二的瓶盖上,用肉眼电能看到沾有血迹。一般认为,咳痰的3%结核菌培养阳性,在确定阳性前后期间临床诊断和培养方面的问题是,认为阳性比率会更高。对气溶胶各种杀菌方法的效果调查,在滤膜上涂布并吸附菌液,进行各种方法杀菌之后,还能检出残存的活菌。从紫外线的杀菌效果,虽然时间较短,但其效果也是很好的,臭氧在低温度下两小时后,对细菌气溶胶的作用不大。
The finger of a person engaged in the work of clinical bacteriological examination appeared to be contaminated with the same species isolated from the specimen. About 3% of the specimen can contaminate the outside of the container. In addition, urine and sputum of 20 to 40% occult positive. Blood culture bottle almost two tenths of the cap, with the naked eye can see stained with blood. It is generally accepted that sputum of 3% of M. tuberculosis cultures are positive and that problems with clinical diagnosis and culture during and after the determination of positive are that the positive rate is considered to be higher. Investigation of the effect of various sterilization methods on aerosol, coating and adsorption of bacterial liquid on the filter membrane, sterilization of various methods and detection of viable viable bacteria. The bactericidal effect from ultraviolet light, although time is short, but its effect is very good, ozone at low temperature two hours later, little effect on bacterial aerosol.
