The Transformation of Pneumococcal Types
R forms of Pneumococcus may be converted into S forms of the homologous Type. In addition to the methods previously reported,-(1) animal passage and (2) growth in anti-R sera,-conversion may be effected by the following procedures as employed by Griffith; (1) The subcutaneous injection, in white mice, of large amounts of living R organisms. (2) The subcutaneous injection, in white mice, of smal...
متن کاملIn Vitro Transformation of Pneumococcal Types
1. Further observations on the conditions under which transformation of pneumococcal types may be induced by in vitro procedures are presented. 2. R cultures possessing only slight degrees of R stability are most suitable for transformation purposes by in vitro procedures. 3. Vaccines prepared from cultures subjected to the action of bacterial enzymes liberated (a) in old broth cultures, (b) du...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
