Many drawbacks to this postulate pop up immediately. The reason is that many organisms could persist long after recovery from the clinical disease. Therefore, an organism B for example, may still exist and could be isolated when a person develops another disease due to organism F. Another scenario occurs when a person is infected by organism B but does not show any symptoms, and at a same time, that person is also infected by organism F, which is truly responsible for those similar clinical symptoms. Another situation could be when organism B lives in a silent state until organism F infects that person, and produce a disease which also reactivated organism B to become an active state without producing any symptoms. Parasitic infections like herpes, malaria or viruses could demonstrate these three cases. Besides that, many organisms could cause several different disease conditions. For example, the bacterium Streptococcus pyogenes could cause several diseases such as scarlet fever, erysipelas, and not just only sore throat (2). Therefore, the bacteria that Koch has isolated did not only cause anthrax, but it may also the source for other
