[Species structure of Salmonellae isolated from mammals, poultry, feed mixtures and the environment 1976-1980].

Studied was the species structure of Salmonella strains isolated in this country from mammals, birds, food products, combined feeds, and objects of the environment over the 1976-1980 period. Differentiated were a total of 10,794 Salmonella cultures, belonging to 67 serotypes of 10 serologic groups after Kauffmann-White's scheme. Most wide-spread proved to be the S. choleraesuis, S. oranienburg, S. dublin, S. typhimurium, S. gallinarum-pullorum, S. enteritidis, S. derby, S. abortusovis, and S. agona serotypes. Combined feeds and individual components were most often found to be the source of S. senftenberg, S. muenster, S. meleagridis, S. oranienburg, S. mission, and S. agona. A dropping trend was established with the relative share of Salmonella organisms isolated from combined feeds and their components as against the total count of isolated Salmonellae in comparison with the 1970-1975 period (2.51 and 8.12 per cent, respectively).
