Abstract
The genes for the cell surface associated antigen CS3, produced by CFA/II type enterotoxigenic Escherichia coli, have been cloned in the plasmid vector pBR322 to produce a family of recombinant plasmids. These plasmids contain a series of HindIII fragments of which a fragment of 4.6 kb is common to all those expressing CS3. One of these plasmids, pPM474, has been subjected to mutagenesis with Tn1725 and deletions generated using Bal31. This has defined a minimum region of 3.75 kb necessary for the production of CS3 on the cell surface and implying genetic complexity as has been observed with other fimbrial antigens. Analysis of the plasmid encoded proteins in E. coli K-12 minicells has confirmed this complexity.Entities:
