A new species of Rickettsia bacterium called Rickettsia finnyi has been identified by researchers after analysis of samples from dogs across the central and southeastern U.S.

A new tick-borne bacterium called Rickettsia finnei has been identified in dogs in the United States. The infection presents symptoms similar to spotted fever, such as fatigue, swelling, and fever. Scientists have yet to determine the specific tick species responsible for spreading the bacterium, though the lone star tick is a possible vector. Cases have been reported in several states, but there may be additional, unreported cases. Pet owners are encouraged to practice tick control, check their pets for ticks, and consult a veterinarian if suspicious bites are found, especially as outdoor activity increases during warmer months.
