Two patients discharged from the neonatal wards on Friday, 14 May 2010 were readmitted with diarrhoea to ward 285 where blood cultures were taken on 18 and 19 May 2010. One blood culture grew a drug-sensitive klebsiella and the other a bacterium that needed further identification. Furthermore, two blood cultures from 2 new babies were collected on 18 May 2010 and tested positive for bacteria growth (microbes needed to be identified further).
