Both natural and experimental Trypanosoma lemmi infections in Norwegian lemmings caused slight anemias and hypoglycemia. Leucocyte counts remained the same. Adrenal and splenic hypertrophy were associated with natural infections whereas only splenic hypertrophy was present in the experimental infection. Grahamella sp. infections were also associated with adrenal and splenic hypertrophy in wild lemmings. It is suggested that blood parasites which are associated with anemia, hypoglycemia and adrenal hypertrophy might also interfere with both male and female reproduction, and should be considered in the interpretation of the population regulation of small rodents.
挪威旅鼠自然感染和实验性感染赖氏锥虫均导致轻度贫血和低血糖。白细胞计数保持不变。肾上腺和脾脏肥大与自然感染有关，而实验性感染中仅出现脾脏肥大。格拉汉氏菌属感染在野生旅鼠中也与肾上腺和脾脏肥大有关。有人认为，与贫血、低血糖和肾上腺肥大相关的血液寄生虫可能也会干扰雄性和雌性的繁殖，在解释小型啮齿动物的种群调节时应予以考虑。
