    摘要: An immunogenic detoxified protein is provided which comprises the amino acid sequence of subunit A of an E. coli heat labile toxin (LT-A) or a fragment thereof in which at least amino acid Ala-72 of the A subunits mutated, preferably by substitution with Arg. The toxoid is useful as vaccine against an enterotoxigenic strain of E. coli and is produced by recombinant DNA means by site-directed mutagenesis. It is also an effective adjuvant.

    摘要: Cloning and sequencing of the Eco RI fragment of B. pertussis chromosomal DNA with 4696 base pairs, containing the genes which code for the five subunits of the pertussis toxin. A hybrid plasmid containing the DNA fragment or its further fragments and a micro-organism transformed by the hybrid plasmid and capable of expressing the cloned DNA fragment or further fragments thereof by synthesis of the pertussis toxin or one or more subunits of the pertussis toxin. The pertussis toxin or one or more subunits of the pertussis toxin so obtained are useful for the preparation of vaccines and diagnostic kits.

    摘要: Helicobacter pylori is known to cause or be a cofactor in type B gastritis, peptic ulcers, and gastric tumors. In both developed and developing countries, a high percentage of people are infected with this bacterium. The present invention relates generally to certain H. pylori proteins, to the genes which express these proteins, and to the use of these proteins for diagnostic and vaccine applications. Specifically, molecular cloning, nucteotide, and amino acid sequences for the H. pylori cytotoxin (CT), the "Cytotoxin Associated Immunodominant" (CAI) antigen, and the heat shock protein (hsp60). are described herein.
