Studies of louse populations on partially disabled mice kept individually to prevent mutual grooming have demonstrated that after initial exposure to the parasite, subsequent populations were limited because of development of acquired resistance by the mice.

During these experiments it was established that a long period of intensive exposure is required for full development of the resistant state. Further, based on a limited period of observation, the inhibitory function appears to be limited to the exposed site rather than generalized over the entire body.

Although detritus that accumulates in a region heavily infested with lice was not a major factor in the resistance to reinfestation that was noted, it could not be eliminated as a minor one.

The successful feeding of larval ixodid ticks on louse-resistant mice in a single experiment indicated that the resistance is probably specific for lice.
