African bacterium resists almost all drugs

It looks like it’s time to pay the piper. The first extensively drug-resistant (XDR) strain of Salmonella typhimurium, called ST313 sublineage II.1, has cropped up in the Democratic Republic of Congo (DRC). This fails to respond to any of the antibiotics that are commonly used in the DRC, except for ciprofloxacin. And to make things worse, one sample has been isolated that shows incomplete response even to this last drug.
