Impact of Vertically-transmitted Dengue Virus on Viability of Eggs of Virus-Inoculated Aedes aegypti
نویسنده
چکیده
Transovarial transmission (TOT) is known to occur in Aedes aegypti. This relationship carries tremendous epidemiological significance. The progeny of virus-inoculated Aedes aegypti were followed for seven generations to observe the impact of the virus on the viability of eggs and their rearing up to the adult stage. Dengue virus was found to exert an adverse effect on the viability of the eggs of the verticallyinfected female mosquitoes and their larval and pupal stages upto adults when compared with the control population. While TOT ranged from 15.5% to 67.5% of the total mosquito populations in seven experimental generations, the corresponding adverse effect of the virus on eggs failing to hatch and grow into adults ranged from 30.0% to 68.1%.

Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus. So the current study was planned ...

BACKGROUND Dengue virus is spread in tropical areas of the world and is the causative agent of dengue fever and dengue hemorrhagic fever. It is horizontally transmitted to humans by infected Aedes mosquitoes, but it is also able to be vertically or transovarially transmitted to insect progeny. OBJECTIVE In this work, we analyzed the vertical transmission of dengue virus in Aedes aegypti mosqu...
متن کاملVertical Transmission of Zika Virus in Aedes aegypti Mosquitoes
Previous experimental studies have demonstrated that a number of mosquito-borne flavivirus pathogens are vertically transmitted in their insect vectors, providing a mechanism for these arboviruses to persist during adverse climatic conditions or in the absence of a susceptible vertebrate host. In this study, designed to test whether Zika virus (ZIKV) could be vertically transmitted, female Aede...
