1457–1463. 1966.—The relative chromosomal location of the
ViA
determinant, a gene required for Vi antigen expression in
Salmonella typhosa
(and present also in
S. typhimurium
), was examined in
S. typhimurium
×
S. typhosa
matings. The position of this gene was determined with respect to the histidine (
his
) and methionine (
metG
) biosynthesis markers, and to the genetic determinants of somatic antigens 5 (
O-5
) and 4 (
O-4
) of
S. typhimurium
. The gene order established by analyses of the hybrid classes resulting from the genetic crosses was
ViA–O-5–metG–O-4
(
his
). This order suggests that neither
ViA
nor
O-5
is a member of the complex of functionally related structural genes which constitute the
O-4
locus. It allows for the possibility, however, of a functional relationship between the genes of the
ViA
and
O-5
loci.
