ECOLOGO-GEOGRAPHICAL ASPECTS OF THE SPREA D OF VIBRIO-ELTOR IN ENVIRONMENTAL OBJECTS

The results of studies carried out over the period of 24 years have re vealed that V. eltor is widely spread in different ecological systems over a considerable part of the territory of the former USSR in the te mperate and subtropical climatic zones. The duration and seasonal char acter of the isolation of these bacteria depend on climatic and geogra phical conditions, and their isolation rate greatly depends on the epi demic situation. The intensity and seasonal character of the isolation of V. eltor have been shown to depend on the character of the ecologi cal system. For some water reservoirs definite biotic and abiotic fact ors capable of influencing the isolation rate of V. eltor have been de termined, but no general regularities involving the above-mentioned fa ctors and constantly ensuring such influence have been established.
