Quantitative studies on some mycobacterial phage-host systems.
Within the last decade, several bacteriophages have been isolated (Gardner and Weiser, 1947; Whittaker, 1950; Hnatko, 1954; Froman et al., 1954) which possess lytic and virus-reproducing activity on saprophytic and pathogenic mycobacteria. Investigations of the mycobacteriophages (Hnatko, 1953; Froman et al., 1955; Hnatko, 1956) have largely dealt with phagetyping and mycobacterial classificati...
متن کاملQuantitative Studies of Brucella Precipitin Systems
Quantitative cross precipitation studies with goat antisera show the three endoantigens of the brucella to be serologically distinguishable. Although the endoantigens of Br. abortus and Br. suis are very similar, they do not react identically, permitting the serological distinction of the two organisms. These differences in cross precipitation may be used to identify an organism of the brucella...
متن کاملQuantitative Studies on Antigenic Recognition
Lymphoid cells from normal animals from two genetically alien but isogenic strains of mice or rats elaborated a factor into the medium during in vitro cultivation. Similarly, lymphoid cells from specifically presensitized animals mixed and cultivated with donor-type lymphoid cells, as well as normal or specifically immunized mouse spleen cells exposed to heterologous red blood cell antigens, fo...
متن کاملQuantitative Studies on Antibody Purification
1. Quantitative data are given on the effect of changes in hydrogen ion concentration and of salt solutions of high concentration on certain immune precipitates obtained at lower salt concentration. 2. Advantage is taken of the shift in reaction equilibrium brought about by the salt in the case of pneumococcus carbohydrate-anti-carbohydrate precipitates to enable the preparation, in a single st...
متن کاملQuantitative Chemical Studies on Hemolysins
1. Total antibody in hemolysins may be estimated from the nitrogen added to sheep stromata suspensions. 2. The method is applied to a number of hemolysins and a correlation, valid to within 20 per cent, established between hemolytic titer and total antibody. 3. When stromata combine with antibody in the presence of guinea pig complement they may take up at least 80 per cent of their weight of c...
