Not illustrated. 1911 edition. Excerpt: ...feasibility in diagnosis of typhoid fever. Barikine8 described the flocculation of invisible precipitates when sensitized and alexinized and exposed to the action of heated (56) bovine serum. He also showed that conglutinin is precipitated by CO2 saturation of heated bovine serum diluted 1-10 in distilled water. Jacobaeus9 and Streng10 considered the possibility of application of the conglutination reaction in the Wassermann reaction for diagnosis of syphilis. Sauli11 demonstrated the possibility of differentiating vegetable proteins by means of conglutination. Streng12 showed that conglutinin exists not only in bovine serum but also in that of most of the related species. The goat possesses least, the antelope more than the cow, which was next highest. The cat, pigeon, and dog have none. The results of tests for conglutinin in the blood of the hen, rabbit, horse, hog. and man were uncertain. Guinea-pigs apparently possess a trace of conglutinin. Streng determined that the property possessed by bovine serum of precipitating lecithin is not identical with conglutinin. Gengou13 proved the presence of conglutinin in the blood of the guinea-pig. He1 also demonstrated the extension of the principle of conglutination to emulsions of the carbohydrates, mastic, and starch. In Gengou's opinion, the sensitization of such emulsions is likely concerned with the protein of the plant. Regarding the conglutination of sensitized red blood cells an interesting fact was adduced. The interaction of both mid-piece and end-piece of alexin is not necessary. It is essential to saturate the red blood cells with mid-piece only in order to insure conglutination by heated bovine serum. Confirmation and extension of the latter's results were attained more
