The Application Of Non Living Things Could Be Protected From Pathogens By Defence Chemicals

Non living things could be protected from pathogens by defence chemicals in the form of disinfectants which are applied thinly on the objects and surfaces. For living things, their defence from pathogens comes in the form of antibiotics and antiseptics, the former given intravenously or through oral administration and the latter applied on the skin whatever the indented purpose may be but does still meet the defence required if applied in the right doses(Lee et al).
Pathogens on the surface are eliminated physically by disinfectants. The mode of operation comes in the form of chemicals, diluted or undiluted for cleaning and by heating; we have noticed this process used in the milk preservation through pasteurisation whereby milk is heated at a very high temperature to kill pathogens. The application of disinfectants varies widely in use for the different settings. For healthcare cleaning to control and keep out pathogens, ethanol is the number one choice used to disinfect and sanitise floors, operation surfaces and surfaces touched the most by people like doors and door closing aids. The liquid based disinfectant normally gets rid of bacteria if it is in the right dilutions or measurements. There are iodine and chlorine based disinfectants both targeting pathogens. The latter is generally used in water treatment and food hygiene and the former widely used for making surgical instruments to render them free from pathogens, thus sterilisation. Antimicrobial
