title: Comparison of methods for the isolation and purification of infectious laryngotracheitis virus DNA.
abstract: Infectious laryngotracheitis virus (ILTV) DNA was prepared using sodium iodide equilibrium centrifugation, preferential phosphorus-32 labelling and extraction with the detergent Triton X 100. The Triton X 100 procedure was found to be the preferred method for preparing DNA for analytical purposes. A method for ILTV titre enhancement is described.
