Table 1 Average titers of engorged mosquitoes, infection, dissemination, and transmission rates in mosquitoes challenged with CVV

From: Infection and transmission of Cache Valley virus by Aedes albopictus and Aedes aegypti mosquitoes

Mosquito species 0 dpi 7 dpi 14 dpi
Average titers of engorged mosquitoes (logTCID50/ml) Infection rate (%)ab Dissemination rate (%)c Infection rate (%)ab Dissemination rate (%)c Transmission rate (%)d
Ae. albopictus 3.7 ± 0.6 (n = 11) 69.2 (45/65) 83.3 (25/30) 56.5 (26/46) 100.0 (12/12) 29.6 (8/27)
Ae. aegypti 4.0 ± 0.8 (n=18) 15.2 (10/66) 100 (4/4) 11.0 (9/82) 100 (5/5) 30.0 (3/10)
  1. aThe infection rate of CVV at 7 and 14 dpi was determined by the isolation of infectious viruses in tissues of dissected mosquitoes or carcasses of whole mosquitoes using Vero76 cells
  2. bSignificant differences between Ae. albopictus and Ae. aegypti were detected using Chi-square test
  3. cThe dissemination rate of CVV at 7 and 14 dpi was calculated based on the detection of infectious viruses in secondary tissues (head, wings and legs) of dissected mosquitoes, which were infected with CVV
  4. dThe transmission rate of CVV was determined by the incidence of positive detection of viral RNA among saliva of infected mosquitoes using nested RT-PCR
