In prokaryotes, the ureases are multi-subunit, nickel-containing enzymes that catalyze the hydrolysis of urea to carbon dioxide and ammonia. The Brucella genomes contain two urease operons designated as ure 1 and ure 2. We investigated the role of the two Brucella suis urease operons on the infection, intracellular persistence, growth, and resistance to(More)
The possibility of expressing a homologous antigen and a heterologous antigen simultaneously in an attenuated Brucella melitensis strain was investigated. The Brucella wboA gene encoding a mannosyltransferase involved in biosynthesis of lipopolysaccharide O-antigen, and the Bacillus anthracis pag gene encoding the protective antigen (PA) were cloned into(More)
