Systematic Veterinary Virology

RESISTANCE

• AHSV is comparatively a stable virus. The virus can survive at room temperature (37°C for 37 days) for nearly a month. However the viruses are inactivated by temperatures >50°C for 3 hr, 60°C for 15 min, 70°C for 5 min.
• The viruses are also stable for up to 20 yr at 4°C; however, inactivated by repeated freezing and thawing. The viruses are stable at basic pH range of 6.3-12.0. The viruses are inactivated by ether, Beta-propiolactone , phenol, iodophores, acetic acid, 2% formalin and  chlorine dioxide.
