By analogy with some trypanosome and malaria infections it is suggested that piroplasms may have the capacity for antigenic variation, thus allowing the parasite to survive in the host for so long albeit as a chronic infection. A population of <jats:italic>B. rodhaini<\/jats:italic> was isolated which was considerably less sensitive in passive transfer experiments to two pools of serum from recovered rats than the normal passage population.<\/jats:p><jats:p>I thank Dr S.
