The New Zealand white rabbit: an experimental host for infecting ticks with Lyme disease spirochetes.
Efficiency of the New Zealand white rabbit as a host for infecting larval Ixodes dammini, I. pacificus, and I. ricinus with Lyme disease spirochetes was evaluated. Rabbits inoculated with infected midgut suspensions of I. dammini from Shelter Island, New York, or fed upon by infected ticks from the same area, responded with spirochetemias of sufficient concentrations to infect as many as 30 percent of the ticks. When infected ticks were used as indicators, it appeared that spirochetemias persisting for up to ten days occurred as early as the tenth day after inoculation or feeding of ticks.
