[Carrier state and body distribution of Salmonella bacteria in healthy piglets and calves].

Studies were carried out to establish the carrier status and the topographic distribution of Salmonella bacteria in the carcass and organs of healthy pigs and calves. A total of 3980 samples were subjected to investigation (m. gracilis, lymphonodus subilicus, lymphonodus praescapularis, lymphonodi mesenterici, liver bile duct, gallbladder, lymphonodi hepatici, and spleen and samples from caecum content taken from 560 slaughtered normal pigs), and a total of 2400 samples (m. gracilis, caput longum of m. triceps brachii, lymphonodus praescapularis, lymphonodus subilicus lymphonodi hepatic, lymphonodi mesenterici, gallbladder, spleen, heart, and kidney and samples from the caecum content taken from 200 slaughtered normal calves. The investigations were carried out with methods routinely employed in the microbiological science and practice with special reference to Salmonella bacteria. It was found that 4.29 per cent of the slaughtered healthy pigs were carriers of Salmonella organisms, 10 serotypes of the groups B, C1, C2, D and E1 of Salmonellae being isolated. Most frequently isolated serotypes in a descending order were: S. anatus, 7 strains; S. cholerae suis, 6 strains; S. derby, 5 strains; S. agona, 4 strains; S thompson and S. dublin, 2 strains; and S. essen, S. lille, S. kottbus, and S. enteritidis, 1 strain. The highest percent of Salmonellae in the slaughtered normal pigs was found in the caecum content (3,75%). No Salmonellae were found in the samples from the slaughtered 200 normal calves and the muscle and carcass lymph node a samples taken from the investigated 560 pigs.
