At least five babies in an Adelaide hospital have been struck down by a rare bacterial infection.

SA Health said two babies in the neonatal unit at the Flinders Medical Centre are symptomatic with Serratia marcescens, with one in a serious but stable condition.

Another three have been found to be carrying the bug but are showing no symptoms.

Southern Adelaide Local Health Director Dr Diana Lawrence said: 'Serratia is an organism commonly found in the gut and environment, which can cause infection invulnerable and unwell patients. 

'Once we became aware of the second baby displaying symptoms, we immediately launched a thorough investigation into the origins of the infection by testing the environment where the bacteria can grow, and for precaution, tested all 40 babies within the unit and all recent discharges.'
