Pasturella multocida type D
Pasurella multocida cytotoxin directly supresses______ of the pig
growth
The Pasturella multocida cytotoxin directly activates what? This does what?
G-protein; affects the osteoblastic/osteoclastic activity resulting in bone loss
Should a pig producer be vaccinating for Pasturella multocida?
Eh. They could be most have ridded their herds of it. If they did they would need to supplement Bordatella bronchiseptica
