Antibody titers to tetanus toxin in human sera were assayed by passive hemagglutination with turkey erythrocytes, enzyme-linked immunosorbent assay, and counterimmunoelectrophoresis. The first two of these tests were shown to be the most sensitive for antibody detection, having the same range of sensitivity and reproducibility. The antibody levels determined by these assays were up to 400-fold ...
An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...
A total of 678 small mammals representing eight species were trapped in western Siberia in 1999-2000 and assayed for the presence of hantaviruses. Eighteen animals, all Clethrionomys species, were antigen positive by enzyme-linked immunosorbent assay (ELISA). Small and medium genome segments were recovered by RT-PCR from six samples from Clethrionomys glareolus and three from Clethrionomys rufo...
