    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: This invention relates to a kit for rapid detection of whether animals, particularly cattle, have been vaccinated with B. abortus RB 51. This vaccination is a brucellosis inhibitor in cattle and the kit includes latex beads which are used, in the latex agglutination test or enzyme-liked immunosorbent assay, to determine whether an animal has, in fact, been vaccinated.

    摘要: The vaccines are prepared by isolating the Brucella genes complementing mutations in the purEK genes of Escherichia coli, physically mapping, determining the DNA sequence, constructing a defined deletion mutation by polynucleotide chain reaction (PCR), introducing a selectable marker into the deletion, and then selecting a purE mutant in Brucella arising by allelic exchange. The resulting Brucella require purines for growth because they lack the purE gene product that is required for the carboxylation of 5'-phosphoribosyl-5-aminoimidazole.
