Eastern Equine Encephalitis Virus in Mosquitoes and Their Role as Bridge Vectors
Figure. Relationship between cycle threshold value and PFU estimated from eastern equine encephalitis virus–infected mosquito pools, Connecticut, USA, 2009. Mosquito pools negative for virus by plaque titration were assigned a value of 0, and mosquito pools negative by quantitative reverse transcription–PCR were assigned a value of 50. Limit of detection by plaque titration (0.8 log10 PFU/mL) is indicated by the dashed vertical line.
