Bacteria are rapidly developing resistance mechanisms to combat even the most effective antibiotics. Each year in the United States over 23000 people die as a result of bacterial infections that have no treatment options,according to the Centers for Disease Control. Infections with antibiotic-resistance bacteria are extremely difficult to treat, requiring costly or toxic medications that do not always work. Scientists are constantly working to understand the mechanisms bacteria utilize to outsmart antibiotics and develop resistance. These mechanisms include metallo-β-lactamases (MBLs), and enzymes produced by bacteria that can bind to and inactivate antibiotics. Enzymes like MBLs are one way bacteria are defying all available tools and fitting antibiotic resistant.
