A STUNNING Miss World finalist had her hands and feet amputated – after contracting a killer bug, according to reports.
Doctors carried out the drastic surgery on Mariana Bridi da Costa after she was struck down with a urinary disease – which can be fatal.
Her boyfriend Thiago Simoes said 20-year-old Mariana fell ill on December 30 – but was initially misdiagnosed with kidney stones.
The infection quickly spread – causing her to go back to hospital for tests that revealed her condition.
Septicaemia set in her limbs, cutting off circulation and forcing doctors to amputate her hands and feet.
Devastated Mr Simoes said: "We are all absolutely distraught and are just praying now that she can pull through.
"She fell ill on December 30 and we took her to hospital where she was misdiagnosed with a kidney stone.
"They gave her some medicine and sent her home. But two days later she started getting worse.
"We took her back to hospital and they said she had a very serious infection.
"She got more and more sick, and had no blood circulation to her limbs.
"First she lost her feet, then on Tuesday she lost both her hands.
"But she is a very strong person and we just want her to survive."
Miss Bridi is in a serious condition on a ventilation machine in hospital in Serra, in the southeastern state of Espirito Santo.
The infection was caused by the pseudomonas aeruginosa bacteria.
Her father, Agnaldo da Costa, told a Brazilian newspaper that "the concern is over her life".
Mariana twice made it to the national finals of the Miss World contest and last year travelled to China to participate in the Miss Bikini International pageant.
Video footage has emerged of her taking part in a beauty pagent on the internet - which you can see above.
