The Pathogenic Aerobic Organisms of the Actinomyces Group

This little monograph is the result of a study of a collection of micro-organisms belonging to the Actinomyces, Streptothrix or Nocardia group obtained from the National Collection of Type Cultures maintained by the Medical Research Council at the Lister Institute. Miss Erikson has made a systematic study of these micro-organisms and has attempted to classify them. Twenty-five species, including fifteen that appear to be entirely new, are identified and described. Eleven plates aid in the description of the morphologic features. This work will be of particular interest to bacteriologists and pathologists who are concerned with the relationships of this group of organisms.
