Defining the Intestinal Microbiota in Premature Neonates

The investigators will collect daily faecal samples from premature (\<32 weeks) infants in the intensive care unit from the day of birth until they are discharged. By using newly developed molecular detection techniques the investigators aim to define more precisely than has ever previously been attempted, all the species of bacteria present in the faeces. This will enable comparison of the pre-morbid and post-morbid intestinal microbiota (all the bacteria in the gut) in premature neonates.
