摘要: 将90只海蓝褐雏鸡随机分为对照组、毒害艾美耳球虫(E.necatrix)一次感染组和毒害艾美耳球虫两次感染组,应用二重PCR方法,通过对肠道组织热休克蛋白-90 (HSP-90) mRNA表达的检测,较全面系统地研究了毒害艾美耳球虫感染对雏鸡肠道组织HSP-90 mRNA表达的影响。结果发现,14日龄雏鸡经口第一次感染毒害艾美耳球虫后0~14 d,其肠道组织HSP-90 mRNA表达虽然不同程度的低于对照雏鸡,但总体呈上升趋势;上述雏鸡于28日龄时再次攻击性感染毒害艾美耳球虫,其十二指肠、空肠和回肠HSP-90 mRNA表达均呈先下降后上升,而盲肠HSP-90 mRNA表达始终呈下降趋势。28日龄雏鸡一次性大剂量感染毒害艾美耳球虫后,其十二指肠、空肠、盲肠HSP-90 mRNA表达均下降,而回肠HSP-90 mRNA表达先下降后上升。结果表明毒害艾美耳球虫感染雏鸡初期,肠道组织HSP-90 mRNA表达受到一定抑制,其表达量与肠道组织细胞损伤程度密切相关。

Abstract: The 90 chickens were randomly divided into control group, E.necatrix one time infection group and E.necatrix two times infection group.We used duplex PCR method to test the expression changes of HSP-90 mRNA in intestinal tissue of chickens infected with E.necatrix and researched the effects of it comprehensively and systematically.The results were showed that after 0 to 14 days the expression of HSP-90 mRNA in intestinal tissues of 14-day-old chickens infected with E.necatrix presented a upward trend though it was lower than the control chickens.These chickens were infected with E.necatrix again at 28 days, HSP-90 mRNA expressions of duodenum, jejunum and ileum decreased and then increased.However, it always showed a downward trend in appendix.When 28 days chickens were infected with high-does E.necatrix once, HSP-90 mRNA expressions of duodenum, jejunum and appendix were in a declining curve.While it was increased originally and then decreased in ileum.This study indicated that HSP-90 mRNA expressions in intestinal tissue of chickens infected with E.necatrix were inhibited at first, and the expression quantity was closely related to the degrees of intestinal tissue damage.

Key words: E.necatrix; chicken; intestinal tissue; HSP-90 mRNA expression
