I don't have this reference, but it sounds like it addresses, albeit
tangentially, the possibility of bloodborne Toxoplasma transmission: Tissue
culture isolation of Toxoplasma from blood of a patient with AIDS. Arch Int
Med 145:925, 1985.
Will check for other references and report anything helpful.
