pacifarin Med.|pæˈsɪfərɪn|

Any biologically produced substance which, when introduced into an organism, protects it from the harmful effects of an infection without killing the pathogen.
1963H. A. Schneider in Proc. Amer. Philos. Soc. CVII. 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. (I wish to thank my colleague, Dr. Ludwig Edelstein, for guiding me in this choice.) The particular pacifarin, 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. 1967Daily 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. 1975Infection & Immunity XI. 69/2 Certain bacterial products other than enterobactin are also now known to possess pacifarin activity. |
