Mycobacterium tuberculosis disinfection

Alcohols, particularly ethanol [64-17-5] and 2-propanol [67-63-9] are important disinfectants and antiseptics. In the aUphatic series of straight-chain alcohols, the antimicrobial activity increases with increasing molecular weight up to a maximum, depending on the organism tested. For Staphylococcus aureus the maximum activity occurs using amyl alcohol [71-41-0], for Salmonella typhosa, octyl alcohol [111-87-5], CgH gO (43) ioT Mycobacterium tuberculosis...

Intermediate-level disinfection inactivates Mycobacterium tuberculosis, vegetative bacteria, most viruses, and most fungi but does not necessarily kill bacterial spores. Low-level disinfection can kill most bacteria, some viruses, and some fungi but does not kill resistant microorganisms such as tubercle bacilli or bacterial spores.
