Magnetoelectric Effect in Amorphous Ferromagnetic FeCoSiB/Langatate Monolithic Heterostructure for Magnetic Field Sensing.

This paper investigates the possibilities of creating magnetic field sensors using the direct magnetoelectric (ME) effect in a monolithic heterostructure of amorphous ferromagnetic material/langatate. Layers of 1.5 μm-thick FeCoSiB amorphous ferromagnetic material were deposited on the surface of the langatate single crystal using magnetron sputtering.

Immunochemical characterisation of Vibrio cholerae O139 O antigens and production of a diagnostic antiserum without absorption.

Rabbits and mice immunised with chemically extracted O-antigens (O-Ags) of Vibrio cholerae O139 (O-AgB and O-AgD) developed antibodies (Abs) which appeared to be highly specific in ELISA for the relevant antigens and V. cholerae O139 strains without absorption, in contrast to the Abs against the heated O-Ag (O-AgH). An ELISA test based on the use of these Abs was shown to detect V.

[Synthesis of protective antigens during submerged cultivation of Vibrio cholerae].

The effectiveness of dot immunoanalysis for evaluating the dynamics of the synthesis of O-antigen, cholera toxin, neuraminidase, adhesin CFA1 in the process of the reactor cultivation of V. cholerae used for the production of oral chemical cholera vaccine is shown. The established regularities of the synthesis of the protective antigens of V.

[Comparative study of the synthesis and specificity of enterotoxin from Vibrio cholerae O139 serotype using monoclonal antibodies].

Strains of V. cholerae serovar 0139 showed a higher intensity of multiplication and lesser nutritive requirements and produced 2-5 times higher amounts of enterotoxin during in-depth culturing than cholera vibrios of groups O1 and non-O1. R-forms of V.

[The use of a new strain of Vibrio cholerae O139 as a producer of an enteric chemical vaccine].

Conditions for the submerged cultivation of a strain of V. cholerae O139, were worked out. These conditions ensured a high yield of biomass, soluble O-antigen and exoenzymes (proteinase, phospholipase A) into the culture medium, which exceeded their production by strains of serovar O1, respectively, 2, 3, 4 and 8 times.
