Abstract
The relative DNA levels of different developmental stages ofBabesia bigemina andB. canis were measured by cytophotometry using the fluorochrome Hoechst 33258 as a staining dye. The DNA measurements provided direct proof of sexual reproduction, i.e., fusion of gametes resulting in the formation of zygotes followed by a meiotic division. BothBabesia species are considered to be typical members of the genusBabesia; however, the DNA measurements revealed important differences in the life cycle of these parasites, indicating thatBabesia species are not characterized by a life cycle, which is specific for this genus.
