    Snippet: Vero cells were infected with each Aram virus stock in the presence of trypsin as described above. The culture supernatants were collected 48 h post-infection (hpi) when 70% CPE commonly developed. Virus titers were measured by end-point titration in 96-well plates using 10-fold serial dilutions of the supernatant samples in triplicate for each dilution to determine the amount of virus required to produce CPE in 50% of the inoculated Vero cells. .....
    Document: Vero cells were infected with each Aram virus stock in the presence of trypsin as described above. The culture supernatants were collected 48 h post-infection (hpi) when 70% CPE commonly developed. Virus titers were measured by end-point titration in 96-well plates using 10-fold serial dilutions of the supernatant samples in triplicate for each dilution to determine the amount of virus required to produce CPE in 50% of the inoculated Vero cells. The 50% tissue culture infectious dose (TCID 50 ) per mL of virus stock was calculated using the Reed and Muench method [25] .
