Abstract

Aims: To determine the spectrum of organisms with their sensitivity pattern and to explore whether the organisms isolated from inborn and outborn groups of neonates are identical or different. Methods: A total of 100 (50 inborn and 50 outborn) neonates were included in the study and 100 samples/swabs were taken from each site, viz axilla, umbilicus, groin, nose and stool at 6 hrs and 72 hrs. Individual swab sticks containing different samples were inoculated on blood agar as well as MacConkey agar media plates and incubated overnight at 37°C. Specific identification of individual organisms was carried out by an automated system. Results: From all the swab regions, common gram negative pathogenic organisms were Klebsiella sp. followed by Acinetobacter sp., whereas, common gram positive pathogenic organisms were Staphylococcus aureus and undoubtful pathogen CONS. No statistically significant dissimilarities were observed among the nature of organisms isolated from inborn and outborn groups at 6 hrs and 72 hrs after admission. Similarly, the sensitivity patterns of the organisms isolated both from inborn and outborn babies were also identical. Conclusion: The similarities among the bacterial colonization and their sensitivity pattern seen in our study participants make us infer that there might be single ward for the care of inborn and outborn neonates. This possibly obviates the need for segregating the outborn neonates as bacteriological milieu is identical in both the groups. This in turn will reduce the cost and complexity of treatment.
