人类致病性病毒达150种以上,不同病毒对消毒药物的抵抗力各有不同。一般说来,病毒对化学剂的抵抗力介于细菌与芽胞之间,也有一些病毒抵抗力可小于细菌,但所有已知病毒的抵抗力均比芽胞要小。化学药物灭活病毒的机制,主要是破坏病毒结构中的传染性核糖核酸链,使主键断裂,阻碍病毒复制;有些是破坏病毒外层结节、纤毛、刺突等吸附器,使病毒不易吸附于宿主细胞;也有通过损坏病毒包膜或外壳,使传染性核糖核 More than 150 human pathogenic viruses, different viruses have different resistance to disinfectants. In general, the resistance of the virus to chemicals is between bacteria and spores, and some of the viruses can be less resistant than bacteria, but all known viruses have less resistance than spores. Chemical drugs inactivation of the virus mechanism, mainly to destroy the virus structure of infectious RNA strand, the primary key fracture, hinder the virus replication; some damage to the virus outer nodules, cilia, spikes and other adsorbers, the virus is not easy to adsorb In host cells; there are also infectious ribosomes that are made by damaging the viral envelope or shell
