摘要:
The present invention relates to a method for identifying and/or quantifying an anti-infective compound. Furthermore it relates to a method for identifying and/or quantifying a mutation in a virulence factor of a pathogen of a host organism that reduces the virulence of the pathogen to a unicellular test organism.
摘要:
A series of genes from Pseudomonas aeruginosa and Klebsiella are shown to encode products that are implicated in virulence. The identification of theses genes therefore allows attenuated microorganisms to be produced. Furthermore, the genes or their encoded products can be used to identify antimicrobial drugs, diagnostic methods for the identification of a pathogen-associated disease, and in the manufacture of vaccines.

摘要:
The present invention relates to strains of Helicobacter pylori useful for the delivery of biologically active agents. In particular, the present invention provides an isolated strain of H. pylori having: (a) low pathogenicity; (b) ability to naturally transform; and (c) ability to colonise mouse stomach mucosa without host adaptation.

摘要:
The present invention relates to a gene expression and eradication system for Helicobacter pylori (H. pylori). In particular, the present invention relates to a genetic construct comprising, in the 5′-3′ direction: (a) a promoter sequence and (b) a DNA sequence of interest, wherein the promoter sequence comprises a polynucleotide sequence capable of regulating expression of the DNA sequence of interest in Helicobacter pylori and wherein said promoter sequence is modified to comprise a tetracycline (tet) operator sequence.
摘要:
The present invention relates to a means of controlling infection persistence of Helicobacter pylori (H. pylori). In particular, the present invention relates to an isolated, genetically modified Helicobacter pylori comprising a functional urease, wherein the contiguous amino acid sequence between amino acid 529 and amino acid 555 of SEQ ID NO:1 is altered to produce said modified Helicobacter pylori which is unable to establish or maintain a persistent infection.

摘要:
The present invention relates to synthetic operons. In particular, the present invention relates to a synthetic operon for integration into a bacterial chromosome of a bacterium comprising a promoter operably-linked to at least two genes, wherein at least one gene is a gene of interest and at least one gene is a gene essential to said bacterium.
