Summary: | The efficacy of
Malarone® alone and in combination with doxycycline (DOXY) against
Babesia gibsoni infections was examined in 8 dogs. In all dogs except
one treated with Malarone®, parasitemia decreased, and anemia improved soon
after initiation of treatment. However, 3 of 4 dogs treated with Malarone®
relapsed, and relapse was inhibited in 2 of 4 dogs treated with Malarone® and
DOXY. All relapsed dogs responded well to the second treatment, but 1 dog relapsed again
and did not respond to the third treatment. Malarone® may be useful for acute
stage of B. gibsoni infections, and at least second repeating treatment
might be effective.
