Disclosed is 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 for ulterior 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.
