E. coli scours in pigs
Piglets are exposed to Escherichia coli, a common bacterium of the gut, within minutes of birth. A number of strains of this common bowel bacterium are pathogenic for pigs.
Unless the piglet receives adequate supplies of maternal colostrum, which is rich in antibodies to, these E. coli strains, then infection may occur.
Good hygiene and temperature control in the farrowing crates are essential in controlling and preventing E.coli scours.
Vaccination of sows with E. coli pilus antigens stimulates them to produce protective antibodies that are passed to the piglets via the colostrum. These antibodies coat the intestinal lining and prevent pathogenic E. coli from attaching to the gut wall and causing disease.
