Figure 2. Viral titers of the clinical strains of E16, E30 strains and E4 in the culture medium of infected primary human islets during 3 days post-infection.

Aliquots of the culture medium were withdrawn day 0 and day 3. Virus titers were obtained using the cell culture infectious dose 50 (CCID50) titration methods. The results are shown as the means ± SD from experiments performed in triplicate.
