The serum dilution neutralization test was evaluated for serological diagnosis of California group arbovirus infections and identification of virus isolates. The technical advantages and the degree of subtype specificity of the serum dilution neutralization test over the hemagglutination inhibition test and the complement fixation test were demonstrated(More)
We report here on a series of studies aimed at characterization of the structural and dynamical properties of the synthetic lipid diphytanoyl phosphatidylcholine, in multilamellar dispersions and vesicle suspensions. The lipid exhibits no detectable gel to liquid crystalline phase transition over a large temperature range (-120 degrees C to +120 degrees C).(More)
Assaying 312 serum samples, we compared four enzymatic methods for serum cholesterol with the Reference Method (modified Abell-Kendall) of the Centers for Disease Control (CDC). The means for the aca, TDx, and SMAC methods (2.27, 2.27, and 2.24 g/L, respectively) were significantly higher (P less than 0.05) than those of the Reference Method and the RA-1000(More)
A virus-free soluble antigen, obtained by ammonium sulfate precipitation of the supernatant fluids of La Crosse virus-infected BHK-21 cell cultures, was more reactive and more specific than infected suckling mouse brain antigen when compared by immunodiffusion and counterelectrophoresis tests. By complement fixation tests, the antigen was cross-reactive(More)
Human sera were treated with kaolin, acetone, and dextran sulfate to determine the best method for removing nonspecific hemagglutination inhibitors. Results indicated that on surveys for group A, group B, and some group C arbovirus HI antibodies, dextran sulfate treatment of sera could be used effectively. This method, however, has limited usefulness for(More)
