Abstract:

Seven samples of blood plasma have been tested by electron microscopy. All of them were serologically HAA-positive. They originated from blood donors who externally appeared healthy. Two of the plasma samples originated from donors, whose previous donations were suspect of having caused transfusion hepatitis. In accordance with the serological findings immunodiffusion and counter-immunoelectro-osmophoresis HAA particles could be demonstrated in all blood plasma units by means of the electron microscope. In all cases spherical particles of about 20 nm, in four cases additionally tubular forms of the same diameter, were seen. Modified author abstract
