In contrast, the American Public health Association, the United States Public Health Service, and the British Ministry of Health include physical antimicrobials in the sideline official definition: "Disinfection--killing of pathogenic agents by chemical or physical means directly utilize (1:19)." Finally, Block (1991) nones that at that place are at least five different elements which should be included in any definition of disinfection. These are that a "disinfectant (1) removes infection, (2) kills, not just inhibits, microorganisms in the vegetative stage, (3) does not necessarily kill spores, (4) is ordinarily a chemical barely can be a physical agent, and (5) is used totally on inanimate objects, not on the human or animal body (1:19)."

The disinfectants employed in this experiment do not fulfill all of Block's (1991) requirements.

All three baron be used on the human body. For example, shortly later on its discovery in 1834, phenol (also known as carbolic acid) was applied to sewage and garbage as a deodorant. However, somewhat later, the fragile acid was also used to treat wounds (2:14-15). Likewise, both oxacillin and cefotetan capacity be used for therapeutic purposes.
