[Morphofunctional evaluation of the state of cells of APUD-system biomodel during anti-plague vaccine process].

Aim: Study reaction of cells of APUD-system of lymphoid organs and intestine of guinea pigs at the stages of morpho- and immunogenesis in response to administration of Yersinia pestis EV Research Institute of Epidemiology and Hygiene (RIEH) line vaccine strain.

Materials And Methods: Vaccine process was modeled in guinea pigs during subcutaneous infection of animals with culture of Yersinia pestis EV RIEH line vaccine strain. Pieces of thymus, spleen, lymphatic nodes and an area of duodenum were taken for histological study.
