Mr Bolton contracted MRSA after being admitted over another illness

Norman Bolton, 87, died in June from pneumonia after catching the bug.

North East Wales coroner John Hughes said it was clear that the retired factory worker picked up MRSA in the hospital.

Wrexham AM Dr John Marek said he had been assured the hospital was doing everything it could.

Previous inquests in Wrexham last week were held on a man who died after injections for arthritis and a woman who had he hip replaced. All three deaths occurred after contracting the MRSA bug at the hospital last summer.

Accidental death verdicts were recorded last week on Minnie Williams, who was also 87, and Nigel Pritchard, who was 57.

Pneumonia

Monday's inquest, which recorded another accidental death verdict, was told that Mr Bolton, suffered from various ailments including senile dementia, chest complaints and anaemia.

The hearing was told he had caught the MRSA bug previously while in hospital but got over it.

He was transferred for care in local nursing homes, and then contracted MRSA again after going into hospital for a second time.

It caused pneumonia that led to his death, the inquest heard.

The coroner said it was clear that Mr Bolton picked up the super bug again while in hospital after admission for treatment of a different illness.

After the inquest into Mrs Williams' death on Friday the North East Wales NHS Trust said an investigation was being conducted to establish the source of infection.

Brewery worker

"This trust takes the issue of MRSA very seriously, and infection control measures have resulted in a reduction in the number of MRSA infections being reduced by 50% in the last two years, " it said in a statement.

A "thorough investigation" is also being carried out into the case of brewery worker Mr Pritchard, the trust has said.

However, no-one from the trust was available to comment following Monday's inquest.

Local AM Dr Marek said that he had met the hospital's chief microbiologist last week who assured him that the hospital was doing all it could to cut the MRSA rates.

Dr Marek said that he would have to trust the staff to do this.

He also said the public must be assured that the rates at Wrexham Maelor are no worse than the average and that he was glad that the Welsh Assembly Government were now going to release MRSA statistics.
