title: Siderochrome production by Yersinia pestis and its relation to virulence.
abstract: P+ plague strains contained more siderochrome-producing organisms than P-. Siderochrome enhanced the mouse virulence of an F1+Vw+P1+P-Pu+ strains, inhibited P1 activity, and could be assayed by a paper disk titration method.
