  • Abstract:

    1. The transmission of Th. ovis by the two host tick Rh. evertsi was successful in six susceptible splenectomized sheep. 2. Th. ovis was picked up by the larvae and nymphae and transmitted by the ensuing adults. 3. Koch's bodies were demonstrated in rare numbers in the parotid lymphatic glands of four sheep. 4. The reaction in all the sheep was accompanied by an increased lymphocyte production in the parotid lymphatic glands, a fever and a relatively mild anaemia. 5. These results once more confirm the observations of Lestoquard (1929) that Koch's bodies form a part of the Th. ovis life-cycle.
