Optimal culture conditions for production of Escherichia coli Adhesin protein coupled to Escherichia coli Heat Labile Enterotoxin A2B in Escherichia coli TB1.

The FimH subunit of type 1-fimbriated Escherichia coli has been determined as a major cause of urinary tract infection. To produce a possible vaccine antigen against urinary tract infection, the fimH gene was genetically linked to the Itxa2b gene, which was then cloned into the pMAL -p2E expression vector. The chimaeric construction of pMALfimH/Itxa2b was transformed into Escherichia coli TB1 and its N-terminal amino acid sequence was analyzed. (omitted)
