Günther Enderlein (1872 – 1968) was a German zoologist, entomologist and later a manufacturer of pharmaceutical products. Enderlein got some international renown because of his insect research but in Germany he became famous because of his concept of the pleomorphism of microorganisms and his hypotheses about the origins of cancer, based on the work of other scientists. His hypotheses about pleomorphism and cancer have now been disproved by science and have only some historical importance today. Some of his concepts are however still popular in complementary medicine. A controversial blood test is named after him: dark field microscopy according to Enderlein.

Life[edit]

Enderlein was born in Leipzig, the son of a teacher. He studied in Leipzig and Berlin and got his PhD in 1898 as a zoologist. He became professor in 1924. First he worked as assistant at the Museum für Naturkunde in Berlin, and went later to Szczecin, now in Poland but at that time in Germany. During the First World War he worked as a military surgeon major even though he was a biologist, as there were not enough physicians available at that time. He returned to Berlin in 1919 and remained there until 1937. After 1933 he became production manager in a small pharmaceutical company: Sanum (that later became Sanum-Kehlbeck). In 1944 he founded his own pharmaceutical company IBICA in Berlin, transferred later to Hamburg. He was also the publisher of a newspaper called Akmon. After his death, IBICA and Sanum merged in 1975 to form the Sanum-Kehlbeck company which is still active today.

Scientific work[edit]

Enderlein published more than 500 scientific articles, mostly about insects. He worked in taxonomy and systematics of many Diptera families. Many insects were named by him and some still carry his name. His way of distinction by external characteristics led to some disputes inside the scientific community of that time (see Zwick 1995 for details). Enderlein was mostly interested in the fly family, Simuliidae.

In 1916 he published an article about spotted fever.

Theories on pleomorphism and the origins of diseases[edit]

He caused more sensation, however, when he developed and published his concepts about the pleomorphism of microorganisms. The concept of pleomorphism was quite controversial at the end of the 19th and the beginning of the 20th century. Eventually the monomorphism concept of Louis Pasteur was accepted by the scientific community in the 1950s.

The term pleomorphism comes from the Greek pleion = more, morphe = form, and was apparently created by French chemist and biologist Antoine Béchamp (1816–1908). Similar concepts were known in ancient times as concepts of abiogenesis but these were disproved during the 18th century.

Based on the early work of Béchamp, who was an opponent of Louis Pasteur, and based on a point of view of contemporary Wilhelm von Brehmer (1883–1958), and on his own microscopic observation, he developed his own complicated pleomorphism hypothesis. He was convinced that every microorganism would pass through a particular development-cycle, that he called cyclode (bacterial cyclode). Béchamp had issued earlier the opinion that in every animal or plant cell there were small particles, that he called microzymas or granulations moleculaires. These particles were able to transform into pathogen bacteria under certain circumstances. Pasteur and the majority of the scientific community at that time did not accept this opinion, although later studies by renowned bacteriologists suggest that the scientific community was becoming more favorable to pleomorphism up until the mid-1900s.[1][2] These studies were inconclusive and subsequently disproved.

At that time it was also known that plasmodia (the causal agents of malaria) were able to change form during their different developmental stages.

In 1925 Enderlein published his main work: Bakterien-Cyklogenie. He developed not only a complex hypothesis, but at the same time he created also his own terminology that makes reading his papers difficult or even impossible. He stated that small harmless and beneficial herbal particles were present in every animal or plant which may transform into larger and pathogen bacteria or fungi under certain circumstances. The smallest particles are called protits, symbionts or endobionts. Protits are, according to Enderlein, small colloids of proteins, sized between 1 and 10 nm. Enderlein distinguished between acid and alkaline symbionts. These particles are able to be transmitted via the placenta before birth.

Enderlein was convinced that these small particles were harmless and necessary for health. Only the larger organisms developed out of these particles were pathogenic bacteria or fungi, Enderlein uses the word valent for pathogen. The smaller harmless particles are able to interact and to control the larger valent particles or organisms by their ability to destroy them by a process of merging. After death the smallest particles survive and may serve for another host-organism, and they participate in the process of decomposition.

A disturbance of the symbiotic friendly coexistence between the smaller particles and the larger organism would start a dangerous situation he called mochlosis that leads at the end to a disease, facilitated by a wrong way of thinking and living. In such a case, he speaks about an increase of valenz, the most primitive protits would build up one-dimensional chains, called filit. These filits may build up a two-dimensional and later three-dimensional net of filits. But this only at a pH higher than 7.3. In a healthy ambiance, such a filit-net may never build up. The filit-net leads to larger particle: the symprotits and later the chondrits. These chondrits have more or less the size of a virus with 15-300 nm in size. The dark field microscopy is able to show them, says Enderlein. If this process continues, we will observe larger particles called mychits, or bacteria-nuclei forming the basis of a bacterium.

  • Apathogenic forms within a cyclode are: protit, filium, filit, spermit, symprotit, chondrit, microchondrit
  • Pathogenic forms (dynamovalent) are: makrosymprotit, makrochondrit, sporoid symprotit, filitnet, mychit (bacterial nucleus), cystit, thecit, diökothecit, bacteria, streptococcus, staphylococus, Mycobacterium tuberculosis, amoebit, zoit.

(other named stages are: basit, phytit, rhabdit, cystit, linit, ascit, synascit.)

According to Enderlein, the different diseases of man are related to particular cyclodes leading to particular microorganisms. He was mainly interested in two cyclodes: the cyclode leading to the fungus Mucor racemosus and the cyclode leading to the fungus Aspergillus niger. The mucor racemosus cyclode leads to diseases concerning the blood, spine and rheumatism. In these cases a marcant filit-net should always be present. An injection of harmless symbionts may help here as they are able to destroy larger valent microorganisms.

The Aspergillus niger cyclode leads to diseases of lung, tuberculosis and cancer. In this case, an injection of symbionts may be helpful.

Enderlein was convinced that bacteria may increase in number or by asexual division or by another sexual way of merging the two nuclei before division.

He developed bacteria and fungi may regress or downgrade back to harmless particles, but this process is only possible in a healthy host organism. He believed the use of some catalytic acting drugs might support that process: the chondritins.
