Clinical Trial Summary

This study aims to determine whether a parent-to-child nasal microbiota transplant (NMT) can seed and engraft parental organisms into the neonatal microbiome and increase the neonatal microbiome diversity.

Description:

This parent-to-child NMT study will test the effect of an anterior nares, or nasal, microbiota transplant (NMT) on seeding, engraftment, and diversity of the neonatal microbiome. Neonates admitted to the Johns Hopkins Neonatal Intensive Care Unit (NICU) will be screened and parents will be approached for enrollment in the study. After consent and baseline screening of parents and neonates, eligible neonates will undergo an NMT.

3. Parent/adult provider has been in close contact with someone in the last 7 days who had a respiratory viral infection, like the cold or the flu?

4. Parent/adult provider tests positive on baseline screening test for S. aureus nasal colonization.

5. Parent/adult provider tests positive on baseline screening test for a respiratory pathogen.

6. Parent/adult provider is not able to provide written informed consent

7. Parent/adult provider is not able to be present at the bedside at the time of intervention.

8. Parent/adult provider has history of chronic sinusitis, cystic fibrosis, or an infection with a multi-drug resistant organism.

9. Inability or unwillingness to complete the Donor questionnaire or a positive response to any question on the Donor questionnaire
