Weakly haemolytic intestinal spirochaetes, distinct from both Serpulina hyodysenteriae and Serpulina innocens, have been reported to cause a disease called intestinal spirochaetosis, or spirochaetal diarrhoea, in weaned pigs (1, 2, 3, 4) . Infected animals develop a sloppy mucoid diarrhoea and a reduction in growth rate. These spirochaetes are slightly more slender than S. innocens, and characteristically only have 4-6 axial flagellae ( 5). Strain P43/6/78, which was isolated from the first recorded case of porcine intestinal spirochaetosis ( 1), has been deposited with the American Type Culture Collection (as ATCC 51139) as the type strain of a possible new genus and species of spirochaete ( "Anguillina coli") ( 5). In the current study we have used a polymerase chain reaction (PCR) amplification of a section of the region encoding the 16s ribosomal RNA gene as a rapid and specific means of identifying these bacteria.
