Transmission of the sylvatic form of typhus infection caused by Rickettsia prowazekii is associated with which animal?

Explanation:
Rickettsia prowazekii has a sylvatic cycle in wildlife, separate from the human-louse transmission that causes epidemic typhus. In this wild cycle, certain animals serve as reservoir hosts, maintaining the bacteria in nature and enabling occasional human exposure through contact with the animals or their ectoparasites. In North America, the classic reservoir for the sylvatic form is the squirrel, especially the flying squirrel. The other animals listed are not the established sylvatic reservoir for this bacterium. So, the animal associated with the sylvatic form is the squirrel.
