Resumo: | There exists no biochemical test allowing to define the pathogenicity of a bacterium, still less for a Vibrionaceae. Two essential characters are to be retained to hold responsible an isolated germ, for an illness: 1) the binding factor, the identification is difficult but a double diffusion of agar should simplify the method; 2) the search for the choleric toxin or a common part of the choleric toxin (toxin LT or ST of E. coli ). Here again, simplified techniques may be used. The acquirement of a plasmid responsible for the binding factor or for the toxin production of the non-pathogenic Vibrionaceae in the origin of certain epidemic diseases in France and in the world. Frequently, epidemics due to common germs (Aeromonas hydrophila of Africa) lead to cholera outbreaks. That is why it is necessary to have a thorough knowledge of the distribution map of bacteria genetically capable of being pathogenic: a) ubiquist choleric vibrio regarding their ecological sites out of the disease outbreak; b) the halophilous vibrio essentially present in marine or lagoon environments, frequently in seafoods resulting in food intoxication, and Vibrionaceae contaminants of drinking water.
