A 20-year-old model who was a finalist to represent Brazil in the Miss World contest has reportedly had her hands and feet amputated after contracting a severe urinary infection.

Mariana Bridi da Costa was sedated in a hospital in Serra, in the south-eastern state of Espirito Santo, and on artificial respiration following the procedures, according to several newspapers.

Bridi was diagnosed with a pseudomonas aeruginosa bacterium infection, which can often prove fatal.
