Antigenic relationships between 12 locally isolated bdellovibrios and 3 established reference strains (109D, 6-5-S, and UKi2) were investigated. Antigenicity of the strains was examined by use of the micro-complement fixation test, the serum and complement bactericidal test, and the immunodiffusion test. Antisera were prepared against one of the local strains (MS7) and against one of the establ...

A comparison of the livetin of egg yolk and serum globulin of the common fowl using (a) anaphylactic and (b) precipitin reactions, indicates that the two proteins are very closely related, if not identical. The complement fixation test does not give the same result but indicates a difference between the two proteins. The complement fixation test also shows differences between serum euglobulin a...
