Over-use of antibiotics in fish-for-food industry encourages bacterial resistance and disease
...which can survive in the presence of antibiotics - antibiotic

Attack is the best defence against urinary tract infection
...As the development of resistance to the body's own antibiotic

...ures of the molecule that could be targeted by new antibiotic
drugs. The results appear in this week's online issue of the Proceedings of the National Academy of Sciences (PNAS). M. tuberculosis is dangerous because it hides and persists in the immune cells of our bodies. "It can only persist there because of t...
