title: Agglutinogens, White's 'Q' substance and the common proteins of Enterobacteriaceae.
abstract: Reassessment of the antigens involved in the cross-relation of Enterobacteriaceae point to the common proteins first discovered by White (1932) and named substance Q. All the serological characteristics of substance Q, as described by White, are identical with those obtained with pure enterobacterial proteins.
