Protective antigen was extracted from Bordetella pertussis cells with 1.0 M NaCl and precipitated with ammonium sulfate, 20-40% saturation (designated fraction 15A-1B). The protective antigen was purified further by detergent (Emulphogene BC720) treatment and adsorption to aluminum hydroxide gel (designated fraction 15A-108A). Compared with B. pertussis vaccine and fraction 15A-1B, fraction 15A-108A retained protective activity as assessed by the mouse protection test, but had reduced protein and markedly reduced endotoxin content. Fraction 15A-108A also had reduced leukocytosis-promoting, histamine sensitizing splenomegaly-inducing, and adjuvant activities. Emulphogene treatment provided a relatively simple method for removing endotoxin from a potential acellular B. pertussis vaccine.

Immunization of hamsters by intramuscular injections of an amebic extract and of two of its fractions, emulsified with complete Freund's adjuvant, resulted in protection against the development of amebic liver abscess, following intrahepatic inoculation of axenic trophozoites of Entamoeba histolytica such that Fraction I, Fraction II, and the whole antigen conferred protection to 18 out of 18, 4 out of 18, and 11 out of 18 hamsters, respectively. Splenomegaly was found to accompany the development of hepatic liver abscesses in this experimental system. There was a very high degree of correlation (r = 0.95) between the weights of the abscesses and the spleens. On the other hand, there was no correlation between the anti-amebic antibody titers (determined by the indirect hemagglutination test) and the development of the liver abscesses within the time-span of the experimental protocol used in this study.
