The current situation on anthrax is characterized as unstable. Instability is associated with recurring epizootic outbreaks complicated by human anthrax cases, as people contract infection mainly through contact with sick animals, their carcasses or animal products. Mentioned are new aerosol and par...

Susceptibility of 50 isolates of Bacillus anthracis to 24 antibiotics was tested by the disk-diffusion method and the method of serial dilutions in solid media. The tests allowed to determine the boundary values of the growth inhibition zones and the minimum inhibitory concentrations of the antibiot...

The set of Bacillus anthracis strains and their derivatives with distinct virulence was selected. The strains were characterized as regards phenotypic properties, VNTR-, SNP- and SNR-loci, plasmid composition, genes of toxin and capsule production, and some pathogenecity-related loci. Correlation be...

Evaluated are epidemiological and epizootiological situations on anthrax in the Russian Federation and around the world in 2012. Displayed is the morbidity rate prognosis for 2013.

We present the results of applying functional cytometric test of antigen-stimulated activation basophils to assess specific immunological reactivity in the people with anthrax, and immunized with anthrax vaccine. As a criterion for antigen-specific basophil activation, we measured expression of the...
