Effect of a synthetic Aluminium – Magnesium Silicate (AMS) on Newcastle Disease Virus (NDV) was tested. Equal amounts, of the AMS and of NDV, on a volume to weight (v/w) basis, were incubated for one hour at room temperature, and then centrifuged. The supernatant was tested for NDV titre. Portions of a virulent NDV were similarly incubated with the AMS, and their supernatants tested for morbidity rates on infected chicks. Also, two groups of chicks were infected with virulent NDV intramuscularly (I/m), and by introduction of infected chicks, respectively. Their subgroups were treated by administering AMS through drinking water, to assess its effect on mortality. Incubating NDV with AMS, reduced the viral titre from mean HA, 613 ±86 to 4. 5 ±0.72 (P 0.05) but when infection was by introduction of infected chicks, mortality reduced from 20% to zero (P < 0.05).These results suggest AMS as NDV’s antiviral agent.
