[The effect of recombinant tumor necrosis factor on antibody formation in mice immunized with a preparation of the outer membranes from Francisella tularensis].

The influence of exogenic human recombinant tumor necrosis factor (TNF-alpha) on antibody production in mice immunized with the preparation of F.tularensis outer membranes (OM) was studied. TNF-alpha was injected into mice in doses of 0.

[The characteristics of the antibody response of animals immunized with components of the surface structures of Francisella tularensis].

Antibody formation in animals immunized with one of the components of F. tularensis surface structures was studied. The time course of antibody formation in 20 hamadryas baboons was studied in the passive hemagglutination (PHA) test, microagglutination (MA) test, and indirect enzyme immunoassay, used for the determination of IgG, IgA and IgM antibodies.

[The use of microdot immunoenzyme analysis with visual detection for the determination of tularemia antibodies].

The possibility of using the micropoint enzyme immunoassay (EIA) on a nitrocellulose membrane with the visual evaluation of results for the detection of tularemia IgG antibodies in hamadryas baboons at the postvaccinal period has been studied. The sensitivity of this assay has been compared with that of the passive hemagglutination (PHA) test, the microagglutination (MA) test and EIA with the spectrophotometric evaluation of results in plates. As shown in this study, EIA in the above-mentioned modification can be successfully used for the detection of tularemia antibodies in the blood serum.

[The efficacy of immunoenzyme assay in determining IgG in blood].

The efficacies of two methods for measuring human blood serum IgG, heterogenic enzyme immunoassay (EIA) and radial immunodiffusion in gel (RIG), are compared. The accuracy of both the methods was verified by the data of IgG spectrophotometry; IgG were isolated by ion exchange chromatography from human blood serum. The results of all the three methods were in high correlation: correlation coefficient of spectrophotometry and EIA data was 0.
