PEDS Outbreak Kills Pigs in Philippines

August 29, 2006 — 

Porcine Epidemic Diarrhea Syndrome (PEDS) has been blamed for the deaths of 60,000 piglets in Batangas province in the Philippines since last June.

PEDS, an acute diarrheal disease caused by a corona virus, can cause clinical signs in pigs of all ages. Two syndromes have been characterized, PED Type I affects only growing pigs whereas PED Type II affects all ages including suckling pigs and adult sows. Identified in the 1970's, the disease has been found in Asia and Europe. The current outbreak appears to be most severely affecting suckling pigs and can result in very high mortality in that age group.

Similar to TGE, herd immunity develops two to three weeks after viral introduction and colostral immunity is protective. Reportedly, local farmers are attempting to stimulate passive immunity by exposing late-term pregnant sows to the intestinal contents of affected piglets. Apparently this practice has shown some success as piglets born to sows exposed 3 weeks prior to farrowing appear to be protected.
