Enteric Diseases of Neonates/Nursing Pigs, Screen Shot 2021-10-02 at 1.02…

- - - - History: age of earliest onset, vaccination status of dams, etc. PH of diarrhea - E.coli is only alkaline diarrhea in neonates!
    - - C&S on gut loop or rectal swab. Histopathology (will show minimal villus atrophy). Necropsy submissions must be FRESH: 2-3 live preferred non-littermate piglets in acute stage (sick <24 hours) with typical clinical signs. PCR for fimbrial and enterotoxin genes.
- - - - Transient vomiting, diarrhea (profuse, watery, milk curds, odiferous). Rapid dehydration/weight loss. High mortality & rapid spread. Piling (cold).
    - - Sporadic vomiting, mild diarrhea, inappetence/agalactia (sows), mortality is rare, recovery in 1-2 days. SEQUELAE in breeding herd: sows don't come back into estrus properly, decreased repro productivity. Boars have lower fertility (fever?)
