Sindbis and West Nile Viruses: an electron microscope study of salivary gland infection in the vector mosquito Culex univittatus

Culex univittalus Theobald was infected by intrathoracic inoculation with Sindbis virus and West Nile virus respectively. Salivary glands were dissected out after 7 and 20 days extrinsic incubation and studied by transmission electron microscopy. How the superior vector capability of Cx. univittalus...

Zusammenfassung:	Culex univittalus Theobald was infected by intrathoracic inoculation with Sindbis virus and West Nile virus respectively. Salivary glands were dissected out after 7 and 20 days extrinsic incubation and studied by transmission electron microscopy. How the superior vector capability of Cx. univittalus with West Nile virus over Sindbis virus could be explained by these ultrastructural observations is discussed.
