To attempt to obtain an isolate of the parasite that infected the patient (hereafter referred to as the patient's parasite), whole blood specimens, collected from him in tubes containing the anticoagulant disodium EDTA, were injected into hamsters (Mesocricetus auratus) and jirds. Animal experimentation guidelines were followed.
Attempts to obtain an isolate of the patient's parasite, by injecting specimens of his blood into hamsters and jirds, were unsuccessful (Table 2 footnote).
Attempts to obtain an isolate of the parasite that infected the Austrian patient, by injecting specimens of his blood into jirds, were unsuccessful; the smears of blood from periodic tail snips and PCR analysis of blood obtained by cardiac puncture of the jirds were negative.
The evidence typically has included various combinations of morphologic data, from examination of blood smears; serologic data (usually, but not always, from IFA testing); and data concerning whether jirds or cattle injected with the patient's blood become parasitemic.

Although spirochetes readily pass between ticks confined in the same feeding chamber, none do so when the infected ticks feed on the back of a mouse while noninfected ticks are feeding on the mouse's head (3), when attached to different ears of a jird (5), or when the distance separating the infected from the noninfected ticks is 3 cm (4).
