摘要:

取新生猫空肠和回肠段,以胶原酶/中性蛋白酶消化后分离培养,采用免疫组化法检测细胞角蛋白,结果表明成功分离和培养了猫肠上皮细胞。以PRU株刚地弓形虫缓殖子感染猫肠上皮细胞,第72 h可至细胞破裂,但镜检未见弓形虫转化成有性期阶段。

Abstract:

Small intestine samples of neonatal cat were aseptically collected from the jejunum-ileum region and digested with collagenaseⅪ/dispaseⅠ. Immunohistochemistry results showed that feline intestinal epithelial cells were successfully isolated and could be cultured. Cytokeratin was positive in the cytoplasm of feline intestinal epithelial cells. The cells were infected with the bradyzoites of Toxoplasma gondii Prugniaud strain, and the rupture of the cells was observed on the 72nd day post-infection. The sexual stage of T. gondii did not occur, however.
