    agent. With the decay of the alimentary clot it changes into the dying off of the microbe population and after the ceasing of digestion the accumulation of bacteria renews again. Simultaneously with the changes in the number of microbes their morphology varies. At the initial stage of blood digestion bacilli typical for the agent are dominant. With the decay of the alimentary clot they are replaced by ovoid and spheroid forms. After the ceasing of the digestion cycle the microbe mass is represented by small coccobacteria. During the decrease in the plague agent abundance bacteria are absent mostly often from the midgutmidgutSubject Category: Anatomical and Morphological Structures
