Abstract
This invention involves a chemically transformed chicken hepatocyte derived cell line which is capable of efficiently supporting replication of infectious laryngotracheitis virus (ILTV) and methods for cultivating ILTV using this hepatocellular carcinoma cell line. The virus harvested from these continuous cell culture methods can be used as a vaccine against ILTV infection.
Claims5
A continuous avian hepatocellular carcinoma cell line, wherein said cell line is CH-SAH, containing infectious laryngotracheitis virus.
Cells containing infectious laryngotracheitis virus prepared by culturing said virus in continuous avian hepatocellular carcinoma cell which is from the CH-SAH cell line.
A method for cultivating infectious laryngotracheitis virus comprising culturing said virus in a continuous avian hepatocellular carcinoma cell line, wherein said cell line is CH-SAH.
A method for obtaining infectious laryngotracheitis virus comprising (i) infecting a continuous avian hepatocellular cell line, wherein said cell line is CH-SAH, with infectious laryngotracheitis virus, (ii) culturing said virus, and (iii) recovering virus produced thereby.
