FIELD: biotechnology, in particular immunological and genetic investigations and educatory process.
SUBSTANCE: Claimed avirulent strain of bacteria Vibrio cholerae biovar eltor, serovar Ogava (ctxA-, tcpA-, toxR-, zot-) is isolated from natural water source of open basin in Turkmenistan, doesn't contain ctxA, tcpA, toxR, zot genes and has stable avirulent atoxigenic properties for long-time storage.
EFFECT: strain useful in screening of new drugs for cholera immunoprophylaxis, including ones being obtained by gene engineering methods; as well as in various educatory processes.
