实验动物所携带的寄生虫和其它微生物常可通过引起动物疾病、损害和死亡而影响动物实验。由于寄生虫感染引起的发病率和死亡率通常较低，特别是自然感染寄生虫对实验动物各系统的潜在影响仍不清楚，因此其影响可能被忽略。以红细胞为营养的体内外寄生虫侵袭动物后可发生贫血 Parasites and other microbes carried by experimental animals can often affect animal experimentation by causing disease, damage and death in animals. As the incidence and mortality due to parasitic infections are generally low, the potential impact of naturally infected parasites on various systems of laboratory animals remains unclear and their effects may be neglected. Anemia can occur after the animals in vitro and in vivo with erythrocytes as nutrition support the animals
