Detection of C-type virus by immunoferritin technique in bat lung cell line chronically infected with bovine leucosis virus.

Reported in this paper are morphological studies and tests for the detection of Type-C particles from a line of bat lung cells chronically infected with bovine leucosis virus. The immunoferritin technique was used. Ferritin labelling of Type-C particles was regularly accompanied by black-spot arrangement of ferritin around the virus envelope, which provided evidence to the specificity of this immunochemical technique.
