Vector competence of Culex quinquefasciatus from Santiago Island, Cape Verde, to West Nile Virus: exploring the potential effect of the vector native Wolbachia.

ABSTRACT:

Background

Culex quinquefasciatus plays a crucial role as a vector of West Nile virus (WNV). This mosquito species is widely distributed in Cape Verde, being found in all inhabited islands of the archipelago. However, no data are currently available on the susceptibility of the local mosquito population to WNV. This study aimed to assess the vector competence of Cx. quinquefasciatus mosquitoes from Santiago Island, Cape Verde, for WNV and to explore the potential impact of its native Wolbachia on virus transmission.

Methods

Wolbachia-infected and uninfected Cx. quinquefasciatus female mosquitoes were exposed to WNV lineage 1 PT6.39 strain using a Hemotek membrane feeding system. Mosquito samples, including the body, legs, wings and saliva, were collected at days 7, 14 and 21
