[The characteristics of a cholera outbreak in Pushkino District, the Azerbaijan SSR]. / Nekotorye osobennosti vspyshki kholery v Pushkinskom raione Azerbaidzhanskoi SSR.

The outbreak of cholera in the Pushkino District of the Azerbaijan SSR, caused by the penetration of Vibrio cholerae into the water of the irrigation system, is described. Altogether 2 cholera patients and 39 Vibrio carriers were detected. The etiological agent of this infection was V. cholerae eltor, serovar Ogawa, with typical phenotype characteristics. From all patients and 37 carriers virulent strains and from 2 carriers faintly virulent strains were isolated. In this outbreak family foci were clearly observed, but the transmission of infection through everyday contacts was practically of no importance. The foci with multiple cases were formed due to the action of one transmission factor: contaminated water.

[The etiology of El Tor cholera]. / Etiologiia kholery él'tor.

Vibrio cholerae eltor has been shown to exist in two variants: epidemic (V. cholerae eltor Hly-, tox+) and nonepidemic, or endemic (V. cholerae eltor Hly+, tox-); each of these variants determines the corresponding form of manifestation of the infection among the population and requires a differentiated complex of antiepidemic measures, as well as different tactics for the treatment of patients.
