The different factors affecting rubella HA or HI were studied and the occurrence of rubella HA, also in absence of gelatine, albumin and Ca++, was shown. The influence on HA and HI titers of different systems--diluent and indicator erythrocytes--was also discussed.

HI rubella antibody determination. (A comparison of methods proposed for the removal of non-specific inhibitors).

The Authors consider the different methods so far proposed for the selective removal of non-specific inhibitors for HI rubella antibodies. They show that the best results are obtained by dextran sulphate and acetone treatments, while the kaolin and heparin-MnCl2 procedures should be avoided especially in the serological diagnosis of acute rubella infection. The presence of specific IgM was demonstrated by 2-mercaptoaethanol.

H-1 and X14 parvovirus antibodies in women with abortions or still-births.

Antibodies against H-1 and X14 parvoviruses were found 13.71 and 9.14%, respectively, of 350 sera from women affected by repeated abortions or still-births. On the contrary, only 2.66 and 1.66% of 300 control sera were positive to the two viruses. The difference in the incidence of antibodies appears highly significant (p greater than 0.001). Therefore a possible role of the parvoviruses in inducing abortions or still-births in humans is suggested.
