Comments on tularemia and other tick-borne affections of livestock in Montana

Abstract

This report is offered to call attention to the fact that at least under conditions of localized tick-borne tularemia epizootic on a stock ranch, it is possible for young cattle to be affected and management with regard to control of tick-infestation may be guided accordingly. Details of tests in laboratory animals are supplied to confirm that the isolates were fully virulent though isolates of low virulence from some other natural sources also have been recognized.
