Etymology: < ancient Greek πύθειν to cause to rot ( < the same Indo-European base as Sanskrit pūy- to rot, Lithuanian pūdyti to cause to rot; ultimately < the same Indo-European base as foul adj.) + -genic comb. form.The alleged Greek etymon *πύθογενης cited by Murchison does not appear to be attested.

Medicine. Now historical.

Generated by decomposing organic material or by decay (esp. in pythogenic fever n. at Compounds); of or relating to such generation.

1858 C. Murchison in Jrnl. Royal Medico-chirurg. Soc. 41 221 (note) In the course of this essay I shall bring forward what I consider positive proofs that this fever is produced by emanations from decaying organic matter; and I would therefore suggest for it the appellation of ‘pythogenic fever’.

1874 Times 9 Nov. 7/5 He discusses the so-called ‘pythogenic’ or putrescent theory.

1881 J. Tyndall Ess. Floating Matter of Air i. 15 It was..no problematical pythogenic gas—that killed the worms, but a definite organism.

1938 Isis 28 123 The more common view related infectious disease to microörganisms loosely; and in England the ‘pythogenic’ theory was much in favor.

1993 A. Hardy Epidemic Streets vi. 165 Murchison's pythogenic theory stressed..the danger of faecal effluvia.
