From the literature on the subject of tularemia we realize that some questions remain undetermined in regard to the susceptibility of certain animals and birds to this disease. For example, it is evident that sufficient evidence has not been produced to place the common dog in the group of susceptible or naturally immune animals. Obviously it can be understood that the material required to study the susceptibility of dogs under natural conditions is not always readily accessible. Consequently investigators interested in this phase of the problem have limited their observations to experimental studies. From the few experimental studies we are given the impression that the dog is only mildly susceptible to tularemia, and other opinions indicate that this animal possesses a natural immunity.
In this communication we are prepared to show that dogs can contract tularemia under favorable natural conditions and that a resultant high agglutination titer for Bacterium tularense
