Data are given on the laboratory spontaneous occurrence of trypanosomiasis in young rats. It was demonstrated that the louse Polyplax spinulosa is the main mechanical vector of Trypanosoma lewisi. Unlike the case of the real host, the flea, the trypanosomes do not undergo the whole developmental cycle in the louse.
