摘要: The invention provides strains of bacteria, especially enterotoxigenic E. coli, attenuated by mutations in the genes encoding enterotoxins (LT, ST, EAST1) and optionally further attenuated by deletion of additional chromosomal genes. In addition the invention provides strains of attenuated bacteria expressing immunogenic but non-toxic variants of one or more of these enterotoxins. These bacteria are useful as a vaccine against diarrhoeal disease.

摘要: Described is a process for producing a mutant bacterium which exhibits improved survival and/or growth under a selected growth condition, the process comprising the steps of: (a) generating a pool of mutant bacteria by transposon mutagenesis with an activating transposon (TnA), wherein the TnA comprises a promoter capable of increasing transcription of a gene at or near its insertion site; (b) growing bacteria from the mutant pool under the selected growth condition and under one or more reference conditions to produce two or more test cultures; and (c) comparing the distribution of TnA insertions between test cultures to identify a first class of genes which are disadvantageous for growth and/or survival under the selected growth condition and a second class of genes which are advantageous for growth and/or survival under the selected growth condition.
