Arbovirus identification by an agar-gel diffusion technique.

THE STUDY OF AFRICAN .HORSESICKNESS VIRUS BY THE AGAR DOUBLE.DIFFUSION PRECIPITATION TEST. l-ST ANDARDIZATION OF THE TECHNIQUE

Since the introduction of agar double diffusion test to the study of antigen-antibody reaction by Ouchterlony on 1948, (16) the technique has extensively been used in identification and immunological research studies on different viruses including those of Arbovirus group. (1,2,3,6,8,9,14,15) The first application of gel diffusion to the study of African horsesickness virus, a member of the Arb...

Agar-gel precipitin-inhibition technique for histoplasmosis antibody determinations.

The agar-gel precipitin-inhibition technique has been modified to detect antibodies of Histoplasma capsulatum in sera from human clinical cases and experimental animals infected with this organism. By use of this modified technique, the histoplasmosis can be detected more consistently and reliably than with the direct agar-gel diffusion test, and titers are comparable to those attained by the c...

Comparison of ELISA and Agar Gel Diffusion Techniques in Diagnosis of Human Hydatidosis.

The Study of African Horse Sickness Virus by the Agar Double-Diffusion Precipitation Test l-Standardization of the Technique

Identification of Actinomyces israelii and Actinomyces naeslundii by fluorescent-antibody and agar-gel diffusion techniques.

This study was an attempt to develop a fluorescent-antibody (FA) test to differentiate Actinomyces israelii and A. naeslundii as an aid in their laboratory identification. Two strains of A. israelii (X522 and A601) and two strains of A. naeslundii (X454 and X600), which had received intensive study by several investigators, were used for the immunization of rabbits. Working titers, based on tes...
