Miami (AFP) - A US woman has died from an infection that was resistant to all 26 available antibiotics, health officials said this week, raising new concerns about the rise of dangerous superbugs.
The woman, who was in her 70s, died in Nevada in September, and had recently been hospitalized in India with fractured leg bones, the US Centers for Disease Control and Prevention reported.
The cause of death was sepsis, following infection from a rare bacteria known as carbapenem-resistant Enterobacteriaceae (CRE), which is resistant to all antibiotics available in the United States.
The specific strain of CRE, known as Klebsiella pneumoniae, was isolated from one of her wounds in August.
Tests were negative for the mcr-1 gene -- a great concern to health experts because it makes bacteria resistant to the antibiotic of last resort, colistin.
It was unclear how the woman's infection acquired resistance.
Experts said she had been treated repeatedly in India during the last two years for a femur fracture and hip problems, most recently in June 2016.
Once the bacteria was identified in Nevada, the patient was isolated to prevent the infection from spreading in the hospital.
