Salmonella senftenberg (Group E Salmonella) was first isolated in India in 1963. It became a serovar of concern after 1985 when it caused outbreak in paediatric wards and neonates in India. This study shows gut colonisation of preterm neonates by group E Salmonella sp in Neonatal Intensive Care Unit (NICU) at AIIMS, N. Delhi. A total of 58 preterm babies admitted to the NICU were examined for microbial flora in stool samples on day 3rd, 7th, 14th, 21st and 28th. Organisms were identified by methods based on culture, conventional biochemical and rapid identification kits (BioMerieux). Polymerase chain reaction (PCR) technique for detecting flagellin gene for all Salmonella sp using previously standardised primers detect presence o/Salmonella sp in stool. Five (8.6%) out of 58 babies grew group E Salmonella sp and were also PCR positive. These were further identified as S. senftenberg having antibiotic resistant profile AGKT (Ampicillin, Gentamicin, Kanamycin & Tetracyclin). S. senftenberg could not be identified in any sample from the environment, medical and paramedical staff.
