Abstract:

It· is concluded that they fall into two groups: (a) Typhus group – endemic, murine or rat typhus. (b) Rocky Mountain spotted fever group - fievre boutonneuse, strains “Robertson”, “Appleton”, “Hare”, which are similar and show only minor strain differences. 3. A proposed nomenclature is discussed.
