title: A differential diagnostic criterion for Babesia major and Babesia bigemina vermicules from tick haemolymph.
abstract: 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 micrometer and mature B. bigemina vermicules had a mean length of 11.79 micrometer. This difference provides a new criterion for the differentiation of the two species.
