ABSTRACT
A microneutralization test is described, in which secondary pig thyroid cells are used and end points are determined by hemadsorption with hamster erythrocytes. The method is evaluated and compared with a macromethod, in which the fluorescent-antibody staining technique is applied for reading titers. The micromethod was found to be useful because of its sensitivity and rapidity.
