[The routes of the spread of cholera in the Shamil'skiĭ Mountain District of Dagestan].

The routes of the spread of cholera were analyzed in 273 patients and Vibrio carriers during the outbreak of cholera in a mountainous region of Daghestan during the period of July 18 to September 4, 1994. Cholera was found to spread mainly after funeral repasts and condolence visits accompanied by the dispensation of foodstuffs, transmission being realized through alimentary and contact routes. Under the conditions of the absence of the centralized water supply system in mountain villages and the contamination of water in open reservoirs it was found to be expedient to use, in addition to the recommended complex of antiepidemic measures, small automatic filtration units.

[The epidemic situation re: cholera in the world: a morbidity analysis and trends].

The analysis of cholera morbidity throughout the world over the period of 1988-1992 indicates the existence of a tendency towards an increase in morbidity due to epidemic outbreaks in the countries of South and Central America and in Africa. Using the data of literature, attempts have been made to elicit the causes of the sudden appearance and spread of cholera in South America. The increase of cholera morbidity in Africa is associated with the activization of cholera in endemic foci and intensified migration caused by military conflicts in the countries of Central and East Africa.

[Increased efficiency in the disinfection of sewage by lactic acid bacteria].

The antimicrobic properties have been studied in 30 strains of lactobacilli. As a result a strain, the strongest antagonist relative to choleric vibrios and other enteropathogenic microorganisms, is selected. Lactobacilli are found to retain their viability and biological activity in the activated sludge during the whole period of observation (6 months).
