Abstract

Summary

Studies were conducted on the subcutaneous and intraperitoneal susceptibility to , and of laboratory mice, guinea pigs, and rabbits and of 12 species of wildlife. These wild mammals included: deer mice (), pinyon mice (), montane meadow mice (), desert wood rats (), Ord and chisel-toothed kangaroo rats ( and ), white-tailed antelope squirrels (), and black-tailed jack rabbits (). The mice were generally found to be relatively susceptible to these bacteria, while the rats, lagomorphs, and the squirrels were more resistant. The persistence of serum agglutinins and viable organisms in the tissues of certain of these animals was determined up to 24 months after infection. All four bacterial species caused chronic infection in the animals, but no evidence was obtained to show that they pass the organisms in their excreta or other body wastes. Bacteremia was found to occur regularly in many of the animals during the early stages of infection, and the possibility of transmission by ectoparasites was noted. Mule deer () and sheep were found to be relatively resistant to locally isolated strains of .
