Clostridium botulinum Type F: Isolation from Crabs

Abstract
Two proteolytic strains of Clostridium botulinum type F have been isolated from crabs (Callinectes sapidus) from the York River in Virginia. This is the first time proteolytic strains of this type have been isolated in the United States and the first demonstration of the presence of type F on the eastern coast of the United States.
