A Staffordshire hospital has confirmed that a kidney patient died after developing a rare strain of a hospital infection.
Medical staff at the University Hospital of North Staffordshire said eight patients, including one who died, were affected.
They contracted a resistant strain of ESBL (Extended Spectrum Beta-Lactamase) Klebsiella.
Different variations of the bug have affected 13 patients in total.
A spokesman for the hospital said: “A small cluster of cases of patients carrying a multi-resistant ESBL Klebsiella has recently been detected on an adult ward at University Hospital of North Staffordshire.
“Various different strains have been identified in the 13 cases currently at University Hospital. Eight have a new strain that has not been seen elsewhere.”
Of the 13 cases, only two developed symptoms of the infection which can include septicaemia or pneumonia, he added.
The spokesman said: “The remaining eleven have been diagnosed as carriers and special measures have been put in place on the ward to protect them and other patients.
“One of the patients who developed the infection had a number of other serious conditions and has subsequently died.”
Klebsiella belongs to the group of bacteria which normally colonise the gut, but they may occasionally cause urinary tract infection.
Patients have been isolated from other parts of the hospital as part of “infection control procedures”, he added.
