separation and recombination of babesia divergens and ehrlichia phagocytophila from a field case of redwater from eire.a blood sample received from a field case of redwater in eire caused simultaneous infections of babesia divergens and ehrlichia phagocytophila when inoculated into a splenectomised calf. each disease agent was isolated in a separate splenectomised calf by suppressive drug treatment of the other agent, and blood stabilates were made. the disease agents were inoculated synchronously or asychronously into groups of calves, whose reactions were observed. infection with b divergens had no effect on t ...19761006962
