[The spread of parahemolytic vibrios in humans in the Burgass Region (Bulgaria)].

The presence of parahemolytic vibrios in the water of the Black sea and also in other water bodies, in the hydrobionts, and later in the secondarily contaminated meat products was demonstrated in 1968. In 1973 gastroenteritis caused by parahemolytic vibrios became widespread; 126 cases were confirmed bacteriologically, and 3 cases were found to be carriers. The infected food products were eliminated, and no more cases of the disease were revealed in 1974.
