Pfeiffern.

Brit.

/ˈ(p)fʌɪfə/, U.S.

/ˈ(p)faɪfər/

Origin: From a proper name. Etymon: proper name Pfeiffer.

Etymology: < the name of Richard Pfeiffer (1858–1945), German bacteriologist.With Pfeiffer's phenomenon (see sense 1) compare French phenomène de Pfeiffer :1895 E. Metchnikoff in Ann. de L'Inst. Pasteur 9 438 La découverte de la destruction extracellulaire des microbes dans le liquid péritonéal, ou de ce qu'on peut appeler le ‘phenomène de Pfeiffer’, suggère toute une série de questions touchant le problème général de l'immunité. With Pfeiffer's bacillus (see sense 2) compare French bacille de Pfeiffer (1897 or earlier), German Pfeiffer'scher Bacillus (1908 or earlier; now usually Bacillus Pfeiffer).

Bacteriology.

1. attributive and in the genitive. Designating the lysis of cholera bacteria in the presence of antiserum and peritoneal fluid, later recognized as an example of specific lysis by antibody and complement. Now historical.Described by Pfeiffer in Zeitschr. f. Hygiene u. Infektionskrankh. 14 (1893) 59.
