Flocculation tests in hydatid disease.

A new serological technique of diagnosing human hydatid disease, employing polystyrene latex particles coated with hydatid cyst fluid, and a modified technique using bentonite particles are described. Comparison of the latex test with the complement-fixation test performed on 102 sera has shown a total agreement of 98% and an agreement of 93.1% in the positive specimens. The bentonite test and ...

Comparative immunological studies in liver diseases.

By fractionation of human liver tissue, nuclear, mitochondrial, and connective tissue antigens were prepared. According to the results of serological tests, in conditions associated with substantial damage to the hepatic parenchyma, antibodies reacting with the nuclear and mitochondrial antigens are produced that show practically no reaction with the connective tissue antigen. It is advisable t...

Rabies Sero-antibody Measurement with Seroneutralisation Tests

The reference method for antirabies antibody measurement is seroneutralisation. The general principle of the method is as follows: a constant amount of virus is mixed with constant volumes of serum dilutions. After an incubation step, the remaining virus is detected either by mouse inoculation (clinical signs and death of animals are observed) or by cell culture. These tests measure the "neutra...
