IMMUNOLOGICAL STUDIES OF BOVINE TUBERCULOSIS. III

[Tuberculosis and leprosy; immunological studies].

An intracellular hemolysin of group A streptococci. III. Immunological studies.

Previous reports (Schwab, 1956a) have described the hemolytic activity of an extract of sonically disrupted group A streptococei. This is referred to as sonic extract and the hemolytic activity as intracellular hemolysin. A study comparing the hemolysin obtained by this method, with the previously described streptolysins 0 and S', indicates that the intracellular hemolysin may be a distinct str...

A prospective study of acute idiopathic neuropathy. III. Immunological studies.

The immune responses of 100 patients who presented with an acute idiopathic neuropathy were compared with those of age and sex matched controls. Blood lymphocytes and their subsets were counted with a fluorescent activated cell sorter. CD8+ (putative suppressor) lymphocytes were significantly reduced in the first week of the disease but total lymphocytes, total T and CD4+ (putative helper) cell...

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...
