A new rapid method for automatic complement-fixation tests.

Rapid production of complement fixation antigens for systemic mycotic diseases. I. Coccidioidin: influence of media and mechanical agitation on its development.

The complement fixation test is of great diagnostic and prognostic value in the study of suspected cases of blastomycosis, coccidioidomycosis, and histoplasmosis. As the number of requests for these tests continues to grow along with the increasing awareness of the public health importance of these diseases, the need to produce large stocks of antigens more efficiently has arisen. Accordingly, ...

Evaluation of a new latex agglutination method for detection of antibody to herpes simplex virus.

A new latex agglutination (LA) test (Wampole Laboratories, Cranbury, N.J.) for detection of antibody to herpes simplex virus was compared with a reference complement fixation (CF) method in a premarket evaluation. Of 102 serum samples tested, 19 were LA negative and CF negative, 79 were LA positive and CF positive, and 4 were LA positive and CF negative. An enzyme immunoassay (M. A. Bioproducts...

Automatic apparatus for Wassermann and Reiter complement-fixation tests utilizing the 'discrete-analysis' principle.

Correlation of herpes simplex virus antibody titers and specific lymphocyte stimulation in adult blood donors.

Antibody titers to herpes simplex virus type 1 in sera from healthy adult donors were assayed by complement fixation, microneutralization, and an enzyme immunoassay (ELISA). This last test proved to be the most sensitive method for antibody detection. It was estimated that ELISA antibody titers were up to 40-fold higher than neutralizing antibody titers and up to 100-fold higher than complement...

Histamine Formed during Microbial Spoilage

vorax strain V,. Serological relationships were determined by three procedures: immobilization, agglutination, and complement fixation. Antigenic relationships in general were dependent upon the method employed. The immobilization test provided the best method for uncovering these differences. The complement fixation test did not provide satisfactory identification of the different species.
