Experimental model of transovarial transmission of Tahyna virus in Aedes aegypti mosquitoes.
The progeny of 31 viruliferous Aedes aegypti females infected with Tahyna virus by sucking on viraemic newborn mice was investigated for virus presence. Out of 1587 individuals of the F1 generation, 16 suspensions representing the progeny of 7 females were positive in 146 trials. Individuals of the F1 generation failed to transfer the virus by sucking. Electron microscopy revealed the presence of Tahyna virus particles in the cytoplasm of maturing oocytes inevitably confirming the transovarial transfer of the virus by germinal cells of Aedes aegypti mosquitoes.
