Because five babies were already tested positive for a strain of methicillin-resistant staphylococcus aureus (MRSA), a hospital in Lancashire has closed its intensive case unit (ICU) for newborns.

The affected babies at the Royal Blackburn Hospital, while none of them have been seriously hit by the strain, are being taken cared of in separate area, the East Lancashire Hospitals NHS Trust reported.

"Everything is being done to eradicate this strain of MRSA from the unit," the Trust added.

The hospital would not accept any new babies onto its Neonatal ICU until doctors and nurses were convinced there was no risk of MRSA in the unit, Trust Medical Director Rineke Schram said.

The babies are being continuously screened to find out if their skins are MRSA-infected, she added.

Closed when the infection caused by the Panton-Valentine Leukocidin (PVL) bug was discovered in mid-September, the public was only made aware of such shutting just recently.

Schram is optimistic that the Neonatal ICU will be reopened as soon as the Trust is sure that all the babies are negatively tested for MRSA.

So far, "no new outbreaks and the small number of babies affected is getting even smaller by the day, the NICU unit have done an excellent job in keeping the incident contained," Scram added.

Society.Guardian.co.uk in January this year reported that scientists have discovered that deadly superbug that attacks healthy young people can kill within 24 hours.

The MRSA, which produces a vicious cytotoxin called panton-valentine leukocidin (PVL) toxin, is a highly-virulent strain of MRSA which destroys leukocytes. It has claimed lives in the UK, Europe, the U.S., and Australia.

The PVL can only be dealt with drugs that must kill the bacteria, destroy their ability to make PVL toxins, and clean up toxins that has already been released into the bloodstream, Society.Guardian.co.uk added.

In December 2004, a baby was killed, and five others were infected at an outbreak at Norfolk and Norwich University hospital.

In April 2005, newscientist.com reported the striking back of the superbug that caused serious infections globally more than 50 years ago.

The so-called suberbug can cause sickness from minor infections to pneumonia which can kill 24 hours after the infection as it destroys the lungs.
