The home was closed for two weeks as a precaution

Two of the home's elderly residents have also tested positive for the disease.

About 100 staff and residents at Downshore Lodge, Stalybridge, have been screened after the death of the nurse in July.

The woman, who is believed to have come from South Africa, had been given the all-clear when she was screened for the disease in March 2002 as she started work at the home.

But after she died, a post-mortem examination revealed the presence of TB.

No danger

Managers at the 45-bed nursing home said the two elderly residents who tested positive for the disease were believed to be clear of infection.

They had not shown any signs of symptoms associated with the disease, but would be screened again in two months as a precaution.

The private nursing home was closed for two weeks as a precaution to stop the disease spreading but has since reopened and is admitting new residents.

Dr Lorraine Lighton, interim leader of the Greater Manchester Health Protection Unit, said: "I am satisfied that everything has been done to ensure the safety of residents and staff in the home and that there is no continuing risk to either new residents or the wider public from this incident."
