In vitro cultivation of Babesia bovis in erythrocyte cultures demonstrated that blood from young animals contains a factor(s) responsible for their resistance to severe babesiosis. This factor is independent of antibody, is present in the serum of all young animals tested, and is dialyzable. The presence of this factor results in inhibition of parasite multiplication and the eventual death of the parasite while inside the erythrocyte.
在红细胞培养物中对牛巴贝斯虫进行体外培养表明,幼龄动物的血液中含有一种(或多种)使其对严重巴贝斯虫病具有抵抗力的因子。该因子与抗体无关,在所检测的所有幼龄动物血清中均存在,且可透析。这种因子的存在会抑制寄生虫的繁殖,并导致寄生虫在红细胞内最终死亡。
