Summary
Babesia major mature and immature vermicules in the haemolymph of Haemaphysalis punctata were measured and found to be significantly larger than vermicules of Babesia bigemina. Mature B. major vermicules had a mean length of 15.53 μm and mature B. bigemina vermicules had a mean length of 11.79 μm. This difference provides a new criterion for the differentiation of the two species.
