As part of epidemiological studies the intestinal contents of 300 normal slaughtered pigs were examined for the presence of C. fetus jejuni. Samples were collected from six different slaughter houses. From 182 of these samples (60.7 per cent) C. fetus spp. jejuni was isolated using the method as described by Lauwers (8). Isolates were confirmed by the results of the following tests: oxidase, catalase, motility, growth at 25 degrees C, production of H2S, reduction of nitrate, growth in 3.5 per cent NaCl and utilisation of glucose and urea.
