从事鼠疫实验室工作人员,尽管严密防护也难免与鼠疫病原体接触,偶有发生感染事故。鼠疫实验室与一般细菌性实验室不同,传染性极强,一旦感染,对周围人群直接构成威胁,对社会影响无法估量。 实验证明以下各种正常操作中均有可能构成实验室污染。 使用吸管移液,尤其吹出最后一滴菌液时;摇动培养试管,拔出管塞时;划动接种琼脂平板以及加热白金耳时;混合菌液或取菌样液体滴在桌面上均能引起空气污染。 使用搅拌器或离心机能引起大量细菌分散到空气中,停机打盖2min至1.5h空气中仍有细菌。 注射动物,尤其经鼻腔注入实验动物,可引起空气中大量细菌溶胶粒。 感染动物能使健康动物产生交叉感染,因此实
Plague laboratory staff engaged in, despite close protection is also inevitable contact with plague pathogens, occasional infection. Plague laboratory and general bacterial laboratory different, highly contagious, once infected, directly pose a threat to the surrounding population, the impact on society can not be estimated. Experiments show that the following various normal operations are likely to constitute a laboratory pollution. Use pipette to pipette, especially when the last drop of bacteria is blown out. When shake the tube and pull out the tube plug, swab the agar plate and heat the white gold ear. Mixing bacteria or bacteria- Pollution. The use of a stirrer or centrifuge can cause a large number of bacteria dispersed into the air, stop playing cover 2min to 1.5h bacteria in the air. Injecting animals, especially via nasal injection of experimental animals, can cause large quantities of bacterial sol particles in the air. Infected animals can make healthy animals have cross-infection, so real
