Seasonal changes in the frequency of block formation have been established in C. tesquorum altaicus from the Tuva natural plague [correction of plaque] focus. Distinctions have been observed in the blocking of fleas born in different calendar years. "Young" fleas born the current year block more frequently than old ones born the previous year.
在图瓦自然鼠疫疫源地的阿尔泰田鼠中,已经确定了菌栓形成频率的季节性变化。在不同日历年出生的跳蚤的菌栓形成方面观察到了差异。当年出生的“年轻”跳蚤形成菌栓的频率比前一年出生的“年老”跳蚤更高。
