Young pigs with vomiting and diarrhea are most likely to have which disease?

• A. Transmissible gastroenteritis (TGE)
• B. Porcine epidemic diarrhea virus (PEDV)
• C. Rotavirus
• D. Salmonellosis

Answer: (A)

In neonatal pigs, vomiting with profuse watery diarrhea is most characteristic of infection with the transmissible gastroenteritis virus, a coronavirus that targets enterocytes in the small intestine. This damage to the villi leads to malabsorption and secretory diarrhea, and vomiting is a common early sign in very young piglets. Rotavirus can cause diarrhea but vomiting is typically less prominent; PEDV can produce a similar illness, but the classic presentation most often highlighted for this age group is TGE. Salmonellosis usually presents with diarrhea and systemic signs like fever rather than the prominent vomiting seen with TGE. So the combination of vomiting and diarrhea in young pigs points to transmissible gastroenteritis.
