Photodynamic Inactivation of Newcastle Disease Virus with Acridine Orange1

AUTOR(ES)
RESUMO

Newcastle disease virus in allantoamnionic fluid was photosensitized with acridine orange, and then photodynamically inactivated. The inactivation rate was directly proportional to light intensity and to dye concentrations up to a level of approximately 100 to 200 μg/ml. Inactivation occurred at approximately an exponential rate for the first 4.5 log10 units of virus, and then continued at a decreasing rate.
