Summary
Several species and subspecies of American deer mice, genus Peromyscus, were inoculated with Trypanosoma hippicum.
- 1. In the following species and subspecies Trypanosoma hippicum infection ran an acute course: P. eremicus anthoni, P. e. eremicus, P. e. fraterculus, Mus bacterianus and Mus musculus. No crises of trypanosomes were demonstrable. All animals of the above species succumbed to the disease within two weeks.
- 2. In the following species and subspecies the infection ran a subacute course: P. maniculatus artemisiae, P. m. gambelii, P. m. rubidus, P. m. rufinus and P. m. sonorensis. Frequent crises and relapses of Trypanosoma hippicum were demonstrable in the peripheral blood of these animals. The minimum period of life was 34 days, the maximum over 250 days, and the general average 95 days. From the first sign of infection until their death, their blood was infective and fatal to Mus musculus and Rattus norvegicus, killing them within 15 days.
- 3. The possibility of wild mice being reservoir hosts for pathogenic trypanosomiases is suggested.
