Encyclopedia entry (1928–1936)
Bacteriotropins, properties of immune sera, thanks to which these sera prepare corresponding microbes for better capture by leukocytes. First indicated by Denis and Leclef, thoroughly described and studied by Neufeld and Rimpau. Unlike opsonic properties, which are also possessed by normal sera, B. are heat-stable (up to 55-60°). Neufeld calls the bacteriotropin titer of a serum that minimum quantity of immune serum, which, inactivated for half an hour at 56°, compared to normal, non-inactivated, still enhances phagocytosis.
