Figure 1From: A live attenuated Salmonella Enteritidis secreting detoxified heat labile toxin enhances mucosal immunity and confers protection against wild-type challenge in chickens Components of pJHL65-dmLT. The SE asd + plasmid with ori pBR (pJHL65) harboring a constitutive expression system under which the dmLT cassette was expressed along with a fused bla secretion signal sequence. Lower case DNA sequence (inside the box) depicts codon substitution and corresponding non-synonymous amino acid substitutions, R192G and L211A.Back to article page
