The antibacterial activity of the copper for and depends on its state: metalized, chelated and ionic.

The hypothesis that the antibacterial effect of copper depends on its state was tested. It was studied the antibacterial effect of copper applied to the fabric, copper in chelated and free (ionic) forms on the growth intensity of and in the system after a single or "primary" contact. Classical microbiology methods were used.

Whole-Genome Sequencing of a Vibrio cholerae El Tor Strain Isolated in the Imported Cholera Focus in Siberia.

The draft genome sequence of Vibrio cholerae O1 strain I-1263, isolated from a patient in the imported focus in Siberia, was determined. The established structural features of the mobile genetic elements indicate stage-by-stage formation of a highly pathogenic V. cholerae clone and promote understanding of the mechanisms of evolutionary pathogen transformations.

[Cholera and war].

During last centures wars were the main account of spread of cholera. It is caused by movement of great mass of troops and peaceful populace, acute fall of living circumstances, decline of sanitarium conditions of population aggregates, difficultness or impossibility of effectuating of contra-epidemic measures. Cholera casualty was multifold bigger, the weapon casualty in fighting armies.
