Vertical transmission of Rabensburg virus in three strains of Culex pipiens.*

*MLE, maximum likelihood estimation of infection rates; CpUS, a United States strain of Culex pipiens that contain genetic signatures of both form pipiens and form molestus; CpEU, a European strain of Culex pipiens form molestus; CxM, a United States strain of Culex pipiens form molestus; OP, oviposition; dpi, days post infection; Vertical transmission of RABV was observed in two independent experiments for CpUS and CxM and in one out of two independent replicates for CpEU. All surviving parental females were pooled in groups of five, screened for viral infection, and all pools were RABV positive.†pool size = 5.
