白纹伊蚊感染登革病毒II型后的元素含量变化

目的　研究白纹伊蚊感染登革病毒Ⅱ型 (DV2 )后的元素含量变化。　方法　DV2经胸注射入白纹伊蚊。分别测定感染后 5、1 0、2 0d白纹伊蚊的元素含量 ,并与未感染DV2相应龄期白纹伊蚊的元素含量对比。　结果与结论　感染后 5d :感染组钙、硫、铬含量明显高于对照组 (P <0 .0 1 ) ;锌、钼、铅、铈、氯含量明显低于对照组 (P <0 .0 1 )。感染后 1 0d :感染组钠、镁、锌、锶、铈、硫含量明显高于对照组 (P <0 .0 1 ) ;铁元素含量低于对照组 (P <0 .0 5)。感染后 2 0d :感染组钛、铅元素含量高于对照组 (P <0 .0 5) ;钠、锌、铬、铈含量明显低于对照组 (P <0 .0 1 )。

Changes in Element Content in Aedes albopictus Infected by Dengue Virus Type II

OBJECTIVE: To study the changes in the content of elements in Aedes albopictus after dengue virus type II (DV2) infection. METHODS: DV2 were injected into the thorax of Ae. albopictus. The content of elements in Ae. albopictus was determined on days 5, 10 and 20 after infection respectively and compared with those in the same instar non-infected mosquitoes. RESULTS AND CONCLUSION: For the group of day 5 after DV2 infection, the content of elements Ca, S and Cr increased remarkably compared to those in the control group; while the content of elements Zn, Mo, Pb, Ce and Cl reduced remarkably. For the group of day 10 after infection, the content of Na, Mg, Zn, Se, Ce and S increased remarkably compared to those in the control; only that of Fe was lower remarkably than the control. For the group of day 20 after infection, the content of elements Ti and Pb increased remarkably than that of the control; while the content of Na, Zn, Cr and Ce reduced remarkably.
