Bartonella henselae antibody and PCR assay results in 7 untreated cats (R1) exposed to C. felis allowed to feed on cats with B. henselae infection induced by IV inoculation. Light gray shaded areas indicate samples that were PCR positive; Dark gray areas indicate the days on which the cats were removed from the room because of fever and need for supportive care; exposure to C. felis began on Day 0. None of the PCR negative cats were blood culture positive.
