1 March 2009 Ceramic Powder Made from Chicken Feces: Anti-Viral Effects Against Avian Influenza Viruses
Author Affiliations +

Ceramic powder prepared by sintering of chicken feces, when mixed with avian influenza viruses or an avian adenovirus, inactivated these organisms to below detection levels. When the ceramic powder was mixed with double-distilled water, the pH of the water rose to 10 but the aqueous phase did not show any antivirus activity. After 10 washings with water or five washings with 1M Tris-HCl (pH 8.0), the ceramic powder still retained antivirus activity. Antivirus activity was not affected by the presence of organic material (33% fetal calf serum). When chicks were fed food containing 5% ceramic powder, there was no difference in body weight between normal feeding and the ceramic-mixture feeding. The mode of action of the ceramic powder remains unknown, but it possibly works by adsorbing the virus. These results show that the ceramic powder has antiviral activities and is a potentially useful tool against avian influenza on poultry farms.
