Complement Fixation with Acid-Fast Bacteria: III. In Tuberculosis

Studies on Complement Fixation in Tuberculosis. Iii

The prolonged extraction of the tubercle bacillus with boiling ethyl alcohol, followed by one or more reprecipitations by chilling the hot alcoholic solution, easily yields a preparation very active as antigen in the complement fixation reaction. This preparation gives a precipitation reaction with high dilution of the normal blood serum of a number of species. The precipitation reaction presen...

A Peculiar Infection with Acid - Fast Bacteria in Wood Pigeons

This investigation by workers at the State Veterinary Serum Laboratory, Copenhagen, follows up an observation by Plum ( I bid. 32 (1942) 465) who, in a study of avian tuberculosis among wild bir ds, encountered a peculiar infection in wood pigeons in which acid-fast bacilli were present. which could not be grown on culture media. Prior to the present investigations a similar infection had been ...

The Relation of Certain Bacteria to Non-specific Reactions with the Complement Fixation Test for Lues

Several investigators who have had a large experience with the complement fixation test for lues have called attention to the development in sera of anticomplementary bodies which cause inhibition of hemolysis in both the antigen and control tubes, and they have found that in most instances this property of the serum is lost after heating it for half an hour at 560 C. In some instances, however...
