[Participation of Mycoplasmas in oncogenesis (author's transl)]

The conclusions drawn from the presented data are in agreement with previously issued opinions of the author. Mycoplasmas are, synergistically with other factors, esseential and obligatory for oncogenesis. Distince biotypes of Mycoplasmas from different types of tumors could not be isolated. Mycoplasmas possess the ability to induce various tumors, without regard to their origin, either from tumors and fetuses. It is concludet that Mycoplasmas are infectious agents specific for tumor induction in general, but not for a distinct type. The conviction, presented already in 1948, tthat no malignant tumor occurs without the presence of Mycoplasmas, but in contrast, that numerous infections by Mycoplasmas do not provoke the manifestation of malignent tumors, is maintained.
