Bacillus anthracis, Bacillus thuringiensis and Bacillus cereus are members of the Bacillus cereus group. These bacteria express virulence in diverse ways in mammals and insects. The pathogenic properties of B. cereus and B. thuringiensis in mammals results largely from the secretion of non-specific toxins, including haemolysins, the production of which(More)
Protective antigen (PA) is central to the action of the lethal and edema toxins produced by Bacillus anthracis. It is the common cell-binding component, mediating the translocation of the enzymatic moieties (lethal factor [LF] and edema factor) into the cytoplasm of the host cell. Monoclonal antibodies (MAbs) against PA, able to neutralize the activities of(More)
BACKGROUND Leptospirosis is one of the most important neglected tropical bacterial diseases in Latin America and the Caribbean. However, very little is known about the circulating etiological agents of leptospirosis in this region. In this study, we describe the serological and molecular features of leptospires isolated from 104 leptospirosis patients in(More)
