Lambs share the same clinical signs and pathogenesis with calves, the only difference is that they aren’t associated with F5, as F5 is in lambs only, while F41 is present in calves and lambs

Study Notes
Pathogenesis of ETEC in Calves and Lambs
- Equilibrium between immunity and infection pressure influences ETEC development.
- Insufficient or delayed colostrum intake (low antibody levels) increases susceptibility.
- Early, high-pressure infections contribute to disease.
E. Coli Pathogroup (Neonatal Diarrhea)
- Diarrhea typically appears in the first week of life.
- Fecal consistency varies from pasty to watery, with a foul odor.
- Color ranges from pale yellow-white to occasionally containing flecks of blood.
- Significant fluid loss leads to rapid weight loss (within 6-8 hours).
- Histological examination of the intestinal mucosa usually shows no abnormalities.
