Disinfectant And Antiseptics Flashcards
What are classified as germicides
Antiseptics and disinfectant
Difference between antiseptic and disinfectant
Antiseptic is germicide applied on living things eg the skin
Disinfectant are germicide applied on non living things
What is the mechanism of action of germicide
By denaturing the protein enzymes of bacteria
By oxidizing the bacteria protoplasm( cytoplasm)
By increasing the permeability of bacteria membrane
Properties of germicide include

Broad spectrum
Long duration of action
Non resistance
Types of germicide include
