The present invention concerns a TGC method for inducting targeted somatic
transgenesis in an animal host, whereby bacteria with a foreign DNA
integrated into an episomal vector release, under the control of
eukaryotic regulatory elements forulterior transcription and expression,
said foreign DNA in the case of infection of a foreign organism, organ,
tissue, cell line or individual cells, causing transcription and
expression of foreign DNA and/or foreign protein in said location.
