    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: Virulence-associated antigens involved in adhesin have been identified in several organisms: Haemophilus influenzae biogroup aegyptius; Escherichia coli K1; EHEC E.coli; Actinobacillus actinomycetencomitans; Haemophilus somnus; Haemophilus ducreyi; EPEC E.coli; EA EC E.coli; uropathogenic E.coli; Shigella flexneri; Brucella melitensis; Brucella suis; Ralstonia solanacearum; Sinorhizobium meliloti; Bradorhizobium japonicum; and Burkholderia fungorum. Although the degree of sequence identity between the adhesins is low, they share a common arrangement of domains from N-terminus to C-terminus, namely: a leader peptide; a globular head; a coiled-coil region; and a transmembrane anchor region.

    摘要: A known surface adhesin (NadA) in Neisseria meningitidis contains sequences which correspond to the fusion peptide, HR1 repeat and HR2 repeat seen in the envelope protein of viruses. Fusion inhibitors may thus be used to inhibit meningococcal infection, and the invention provides a compound that can bind to the heptad repeat sequence(s) HR1 and/or HR2 of the NadA adhesin on the surface of a meningococcus, thereby inhibiting the ability of the meningococcus either to infect a host organism or to spread an existing infection.
