Summary Serological examination of 177 strains of haemolytic Escherichia coil from pigs from 95 piggeries showed that 50 isolates from 28 piggeries were agglutinated by serums prepared against 0141:K85ab, 45 from 20 piggeries by 0141:K85ac, 32 isolates from 19 piggeries by 08 and four isolates from two piggeries by 0139:K82. Forty‐six strains from 26 piggeries were unclassified. Ninety strains were isolated from intestine and/or mesenteric lymph nodes and 87 from other organs. Of the 95 outbreaks associated with haemolytic E. coli , 41 were diagnosed as oedema disease, 40 as coli‐enteritis and the remainder were miscellaneous conditions. The clinical and pathological features of outbreaks associated with colibacillosis and septicaemic salmonellosis were compared and discussed.
