Serum samples from 42 diarrhoea-free pigs of two SPF herds and from 295 pigs of unknown history from ordinary herds were tested for coli antibody by the passive immune haemolysis test, using purified cholera toxin (immunologically identical with coli enterotoxin) as antigen. The test was positive in only one pig of the first group, but 107 (36%) of the second group.
