[Localization of antigen F-1 of Yersinia pestis EV by an immunoferritin method]. / Izuchenie lokalizatsii antigena F-1 Yersinia pestis EV immunoferritinovym metodom.

ABSTRACT

The localization of antigen F-1 in Y. pestis strain EV, line (formula; see text) has been studied by means of specific monoreceptor ferritin-labeled antibodies. The study has given direct proofs that antigen F-1 is localized on the surface of the cell wall and in bacterial microcapsules. The substance of the microcapsule is loosely bound with the cell body and easily diffuses into the intercellular space, the antigenic properties of the substance remaining unchanged.
