[Study, by the double diffusion in gel method, of the antigenic constituents of various strains of halophilic Vibrio].

The antigenic relationships among 18 strains of halophilic Vibrio (5 V. para-haemolyticus, 5 V. alginolyticus, 3 V. anguillarum and 5 Vibrio sp.) have been studied by a gel double diffusion test, either within the same species or with the others. Some halophilic Vibrio, named Vibrio sp. and having a uncertain taxonomic position, have been found close related with V. parahaemolyticus or with V. alginolyticus, whereas others are, as well as V. angiullarum, less related to those species.

[Epidemiology of cholera in the world. Development between 1970 and 1980].

The authors present a general review of ten year evolution of the 7th pandemic of cholerae. They discuss the official data known from the country declarations. From the epidemiological features they distinguish a hydric dilution model of cholerae (few cases, few carriers, endemicity) and a direct inter-human contamination type (epidemic outbreaks, no endemicity).

[Immuno-electron microscopy study of Toxoplasma gondii. II. Study of IgM antibodies].

This paper deals with an immunoelectron microscopic study of the localization of IgM vector on the membrane of Toxoplasma gondii using the antibody at the early period of infection. The primary antibody was IgM antibody obtained from rabbit's serum 11 days after the infection of Beverley strain of Toxoplasma gondii from which IgG was absorbed by protein A containing staphylococcus. Ferritine-labeled antibody against rabbit's IgM was used as the secondary antibody. The surface of normal tachyzoites is smooth with two layered plasma membrane. The outer layer shows a three-layer structure which is not found in the inner membrane. The inner membrane is discontinuous with partially lost portion at the head of the tachyzoites. Structure within plasma include conoid toxonems, dark staining vacuoles and nucleus. By reacting with the ferritin-labeled antibody, ferritin particles were found on all over the circumference of the tachyzoites depositing on the surface of the outer plasma membrane, but few on the inner plasma membrane and organelles. It implies that IgM receptors are localized on the membrane surface similarly with our preceding report.
