猪附红细胞体对仔猪猪瘟免疫效果的影响

为探讨猪附红细胞体对仔猪猪瘟免疫效果的影响，本试验利用猪瘟抗体检测ELISA试剂盒，对已注射猪瘟疫苗的69头感染猪附红细胞体的仔猪和31头无猪附红细胞体感染的健康仔猪进行了猪瘟抗体检测．结果表明，感染猪附红细胞体仔猪的猪瘟抗体水平低下，其猪瘟疫苗整体免疫合格率（49．2％）明显低于健康仔猪（93．5％），且显性感染仔猪的免疫合格率（41．6％）明显低于隐性感染仔猪（53．5％）、说明，猪附红细胞体严重干扰了猪瘟疫苗的免疫效果，且干扰程度随着猪附红细胞体感染程度的加深而更为明显。

Effects of E.suis on the immunization against swine fever virus in piglets

We determined the antibody levels against swine fever virus in 69 piglets which with infection of E.suis and 31 healthy ones use ELISA kit after immunizing with swine fever vaccine.The results showed that the integral immunization qualified ratio(49.2 %)in piglets which with infection of E.suis was obviously lower than that(93.5 %)in healthy ones,and the immunization qualified ratio(41.6 %)in dominance infected piglets was lower than that(53.5 %)in recessive infected piglets.It was concluded that E.suis could interfere the immune effects of swine fever vaccine seriously,and the interference degree was coherent with E.suis infection degree.
