Dr Balldt stated that line-listing was done with all affected neonates. An audit with on-site infection prevention and control, training and education was carried out in wards 177 and 184. Nineteen empty, used milk-fed bottles with evidence of residual milk were collected and sent to the National Health Laboratory Services Infection Prevention and Control Laboratory for culture. She further stated that twelve of these bottles grew klebsiella pneumonia but they were still awaiting the antibiogram which would be available by Thursday, 20 May 2010. A further 6 grew a gram- negative bacillus morphologically resembling klebsiella but they were awaiting final confirmatory identification and antibiogram results. One bottle grew a gram-negative bacillus to be further identified.
