[Circulating Salmonella serotypes isolated in the territory served by the Sanitary-antiepidemic Center of Covasna County].

During the 1967-1973 period, the authors followed up the circulation of various Salmonella serotypes and found new serotypes linked to the particular epidemiologic aspects recorded within a small district, without highly populated centers. The results showed a steady increase in the strains isolated during the last 3--4 years. Among the total 2103 strains isolated, S. panama, S. typhimurium and S. bredeney were predominant. The number of serotypes isolated varied between 10 (1968--1969) and 16 (1972). Salmonella strains were incriminated in the etiology of a fairly high proportion of the acute digestive disorders.
