  We present a bilocal isomorphism between the algebra generated by a single
real twisted boson field and the algebra of the boson $\beta\gamma$ ghost
system. As a consequence of this twisted vertex algebra isomorphism we show
that each of these two algebras possesses both an untwisted and a twisted
Heisenberg bosonic currents, as well as three separate families of Virasoro
fields. We show that this bilocal isomorphism generalizes to an isomorphism
between the algebra generated by the twisted boson field with $2n$ points of
localization and the algebra of the $2n$ symplectic bosons.
