Abstract
in English, Norwegian

The udders from 13 culled ewes and liver, spleen, kidney, lung and brain from 15 lambs, 11 months old, were examined for the presence of Listeria monocytogenes (Lm) at slaughter. Lm was isolated from 1 of 13 udders, from 6 of the 15 brains and from 0–4 of the other organs from each of the 15 lambs.

Internal organs from 68 sheep submitted for post-mortem examination were examined in the same way. Lm was isolated from 25 of these animals. Lm was isolated from the brain of 7 of 9 animals with encephalitis, and from 0–3 of the other 4 organs examined. Lm was also isolated from 10–20 % of the organs from animals with other diagnoses. Altogether 9 of 10 animals with encephalitis and 16 of 58 with other diagnoses (28 %) were found to harbour this organism.

Jur frå 13 utrangerte sauer og lever, milt, nyre, lunge og hjerne frå 15 slakta fjorlam blei undersøkte. Listeria monocytogenes (Lm) blei funnen i 1 jur, 6 hjernar og i ø–4 av dei andre organa.

Indre organ frå 68 sjølvdaua eller avliva sauer blei undersøkte på same måten, og Lm blei isolert frå 25 av desse. Lm blei funnen i hjernen til 7 av 9 dyr med encephalitt og i 0–3 av dei andre organa frå desse dyra. Lm blei og dyrka frå 10–20 % av organa frå dyr med andre diagnosar. I alt blei Lm isolert frå 9 av 10 dyr med encephalitt og frå 16 av 58 dyr med andre diagnosar (28 %).
