Strains of Coxiella burnetii were isolated from Dipodomys ordii, D. microps, Peromyscus maniculatus, and Dermacentor parumapertus collected in the Great Salt Lake Desert in Utah. In addition, antibodies against C. burnetii were found in serums of Lepus californicus, Onychomys leucogaster, and Eutamias minimus.
