Detailed explanation-1: -Antibiotics are the substances or chemicals that kill or stop the growth of bacteria. Interestingly antibiotics are isolated from bacteria themselves and few fungi. Bacteria use them to protect themselves from other types of bacteria. Penicillin was the first antibiotic isolated from a fungus called Penicillium.

Detailed explanation-2: -Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite).

Detailed explanation-3: -Halogens, including chlorine, fluorine, and iodine, are also commonly used for disinfection. Chlorine compounds, including sodium hypochlorite, chloramines, and chlorine dioxide, are commonly used for water disinfection. Iodine, in both tincture and iodophor forms, is an effective antiseptic.

Detailed explanation-4: -The best natural disinfectants include alcohol, hydrogen peroxide, vinegar, hot water, and some essential oils. Evidence suggests that in some cases, many of these natural disinfectants can be as effective at killing germs as chemical cleaners like bleach.

Detailed explanation-5: -Antibiotics are medicines that fight infections caused by bacteria in humans and animals by either killing the bacteria or making it difficult for the bacteria to grow and multiply.
