Tuberculosis (TB) is a global health problem estimated to kill 1.4 million people per year. Recent advances in the genomics of the causative agents of TB, bacteria known as the Mycobacterium tuberculosis complex (MTBC), have allowed a better comprehension of its population structure and ...

Activation of the contact system leads to the cleavage of kininogen by plasma kallikrein resulting in kinin release and in the initiation of the intrinsic pathway of coagulation. Proteolysis of kininogen also generates antimicrobial peptides (AMPs) and can be induced by diverse pathogens. ...

Gene duplication generates genetic novelty and redundancy and is a major mechanism of evolutionary change in bacteria and eukaryotes. To date, however, gene duplication has been reported only rarely in RNA viruses. Using a conservative BLAST approach we systematically screened for the ...

Analysis of genetic differences (gene presence/absence and nucleotide polymorphisms) among strains of a bacterial species is crucial to understanding molecular mechanisms of bacterial pathogenesis and selecting targets for novel antibacterial therapeutics. However, lack of genome-wide ...
