case_images: The Figure 4A and B show SIRC cells uninfected and infected with ZIKV respectively. Virus particle or "virion" of 50nm in diameter coming from supernatant sample of SIRC cells infected with ZIKV was observed by electron microscopy (Figure 4C). Ultrathin sections of infected SIRC cells presented virus particles with an outer envelope and inner dense core, structures similar in size and morphology of flaviviruses near endoplasmic reticulum and Golgi complex (Figure 4D).
