Abstract
Salmonella weltevreden strains produced a delayed permeability factor (PF) when tested on depilated rabbit skin. The PF activity could be demonstrated in freshly concentrated culture filtrates as well as in the cell lysates. The activity varied with strain and preparation. The induration and blueing reactions were associated with well marked balancing zones.
