Propagation of Babesia bigemina in "in vitro" erythrocyte cultures resulted in the appearance of the sexual stage of the parasite, characterized by cytoplasmic projections and microtubules. These morphologically distinct parasites were found to adhere to each other, with later fusion of their membranes. No nuclear fusion was observed. The ultrastructure of the sexual stages was described.
双芽巴贝斯虫在“体外”红细胞培养物中的繁殖导致了该寄生虫有性阶段的出现，其特征为细胞质突起和微管。发现这些形态上不同的寄生虫相互黏附，随后其细胞膜融合。未观察到核融合。描述了有性阶段的超微结构。
