Abstract

Temperature is a determining factor for the viral cycle. In this study, we investigate the effect of different temperatures on the cycles of two important arboviruses-Zika (ZIKV) and Chikungunya (CHIKV)-in Vero (mammalian) and C6/36 (mosquito) cells. We compare genome quantification to infectivity at 28 °C and 37 °C in both cell types. Virus-cell interaction was also examined by transmission electron microscopy, allowing the observation of phenomena such as virus-surfing and giant forms for CHIKV, as well as the the scarcity of ZIKV in C6/36 cells compared to its cycle in mammalian cells.

摘要

温度是病毒循环的一个决定性因素。在本研究中，我们调查了不同温度对两种重要虫媒病毒——寨卡病毒（ZIKV）和基孔肯雅病毒（CHIKV）——在非洲绿猴肾（哺乳动物）细胞和C6/36（蚊子）细胞中循环的影响。我们比较了两种细胞类型在28℃和37℃时的基因组定量与感染性。还通过透射电子显微镜检查了病毒与细胞的相互作用，从而能够观察到诸如病毒冲浪和基孔肯雅病毒的巨型形态等现象，以及与寨卡病毒在哺乳动物细胞中的循环相比，其在C6/36细胞中的稀缺情况。
