Abstract

Transmission of Newcastle disease, and avian encephalomyelitis viruses were evident and confirmed, but it requires virus reisolation. Relatively
10% isopropyl alchol and 1% phenolic acid (for Newcastle disease virus), and 10% isopropyl alcohol and 2% formalin (for avian encephalomyelitis virus) were considered the most effective disinfectants on the Newcas tle disease, and avian encephalomyelitis viruses.
Increasing the concentration of these disinfectants not increase their effeciancy, but decreasing this concentration decrease their effeciency.
