Sixty-six paired sera from patients suffering from mumps were examined with Sendai and mumps virus particle antigen: 50% showed a rise of complementfixing antibodies to mumps virus particle antigen only and the rest to both antigens.
This relationship was further substantiated by the occurrence of both antibodies in a proportion of the sera of 362 blood transfusion donors and 978 sera from antenatal patients.
The occurrence of both antibodies in patients' sera is discussed and the conclusion is reached that one of the components of the mumps antigen complex is indistinguishable from the essential components of the Sendai virus.
I am indebted to the Maternity Department of the Edgware General Hospital for supplying the antenatal sera, and to Dr Preston of the Regional Transfusion Centre, Oxford, for the blood donor sera.
