1963 H. A. Schneider in Proc. Amer. Philos. Soc. 107 445/2 As a new and third category of ecological ectocrines, which already embraces vitamins and antibiotics, we add as the first example of its class the substance I have described above, and name the class ‘pacifarins’ from the Latin verb ‘pacificare’, to make peace, to pacify... The salmonellosis pacifarin, is, we believe, addressed only to the typhoid diseases, and for other diseases there are, we postulate, other pacifarins waiting to be identified.

1967 Daily Tel. 10 May 14/6 The basis of the discovery is that a microscopic amount of pacifarin extracted from wheat and dried egg-white will protect mice against infection by salmonella.

1975 Infection & Immunity 11 69/2 Certain bacterial products other than enterobactin are also now known to possess pacifarin activity.
