Contribution to science

Béchamp worked on silkworm diseases, identifying one as due to a parasite — a separate, smaller organism which entered the body from outside, in this case causing disease. However in a period when considerable scientific interest and effort was applied to this problem, his more complex and thorough understanding of the interaction between colloidal lifeforms and their role in disease as is generally accepted today did not have mass audience appeal like that of Pasteur

 whose postulates are the basis of deciding whether a microbe is the cause of a disease. Bechamp however maintained the abandoned pleomorphic theory — essentially that bacteria change form and are not the cause of, but the result of, disease, arising from tissues rather than from a germ of constant form. This has also been called the cellular disease theory, in that scavenging bacteria are supposed to arise from what he called microzymas. "Micro" meaning small and "zymas" referring to a special class of immortal enzymes. He postulated these microzymas to be normally present in matter (including tissues)and that they had either a life or death giving quality depending on the cellular terrain.

His theory was discarded by science in favor of Pasteur's. Other pleomorphists since then have been Wilhelm Reich
