Resumen:
Background: St. Louis encephalitis virus (SLEV) is endemic and autochthonous on the American continent. Culexpipiens quinquefasciatus is a vector of SLEV; however, Culex interfor and Culex saltanensis have also been foundto be naturally infected with SLEV. The aim of this study was to determine the vector competence of C. interforand C. saltanensis for SLEV from Argentina compared with C. p. quinquefasciatus. Culex genus is Cx.?Methods: Female of the Culex species were orally infected by feeding on viraemic chicks that had been inoculatedwith SLEV. Abdomens, legs and saliva blood-fed mosquitoes were analysed by viral plaque assay.Results: Mosquitoes were susceptible to orally acquired infection, dissemination and transmission of SLEV in thesaliva.Conclusions: Our results demonstrate that C. saltanensis and C. interfor are susceptible to SLEV and competentfor its transmission.
