Endotoxins of Pasteurella multocida cause fowl cholera
T
Fowl cholera has always an acute cours
F
Fowl cholera could cause focal inflammation-necrosis in the liver
T
Fowl cholera is the most severe among day-old chicken
F
Fowl cholera is caused by introducing highly virulent Pasteurella multocida strains
