Circovirus in pigs invisibly spreading in the USA - means more MRSA

.
We get yet more confirmation that the pigs are sick with circovirus, and how it is spreading invisibly, this time from the USA.

That means ever more antibiotics to keep sick pigs free from bacterial disease and ever more MRSA in people.
This should have been stopped years ago.

High prevalence of porcine circovirus viremia in newborn piglets in five clinically normal swine breeding herds in North America.




Department of Veterinary Diagnostic and Production Animal Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA 50011, USA.

Porcine circovirus type 2 (PCV2) can be vertically transmitted resulting in fetal infection with or without clinical signs and lesions. The primary objective of this study was to assess the prevalence of intrauterine PCV2 infection in clinically normal newborn piglets in conventional pork production facilities. Five commercial breeding herds located in the U.S. and Mexico were included in the study...

... In conclusion, an unexpectedly high prevalence of PCV2 viremia was detected in healthy sows (serum and colostrum) and their pre-suckle piglets in the five breeding herds investigated and PCV2b was more prevalent than PCV2a. This information adds to the knowledge of PCV2 infection in breeding herds.
