Origin: 1877 ;

 Borrowed from German Symbiose, borrowed from Greek symbíōsis "living together, companionship," from symbiō-, variant stem of symbioûn "to live with, live together" (from sym- {see: |sym-|syn-} + bioûn "to live, pass one's life," derivative of bíos "life") + -sis {see: |-sis|-sis} {mat|quick:1|};

  * Note : As a term in life sciences German Symbiose was promulgated, if not introduced, by the mycologist Heinrich Anton de Bary (1831-88) in Die Erscheinung der Symbiose: Vortrag gehalten auf der Versammlung der Deutscher Naturforscher und Aertze zu Cassel (Strassburg, 1879); a portion of the lecture appeared earlier as "Ueber Symbiose" in Der Naturforscher, 11. Jahrgang, No. 43, October 26, 1878, pp. 400-04. He defines the word briefly as "the living together of differently denominated organisms" ("[das] Zusammenleben ungleichnamiger Organismen," p. 5). De Bary was probably aware of the slightly earlier synonymous term Symbiotismus, introduced by the plant pathologist Albert Bernhard Frank (1839-1900) in "Ueber die biologischen Verhältnisse des Thallen einiger Krustenflechten," Beiträge zur Biologie der Pflanzen, Band 2 (1877), p. 195.;
