E. coli is a common gram-negative bacterium found in the gastrointestinal tracts of pigs. While not all E. coli strains cause harm, the F4/K88 and F18 strains can lead to illness in pigs. Dr. Emily Mauch-Swinford is a geneticist with DNA Genetics. In this episode, she describes the prevalence of these two strains, how genetic resistance can be used to reduce the number of sick pigs and how DNA Genetics is approaching genetic resistance to E. coli
