Impact of early life antibiotic and probiotic treatment on gut microbiome and resistome of very-low-birth-weight preterm infants

Raymond Kiu, Elizabeth M. Darby, Cristina Alcon-Giner, Antia Acuna-Gonzalez, Anny Camargo, Lisa E. Lamberte, Sarah Phillips, Kathleen Sim, Alex Shaw, Paul Clarke, Willem van Schaik, John Simon Kroll, Lindsay J. Hall

This study examines how early antibiotic and probiotic treatments affect the gut microbiome and resistome in preterm infants, finding that probiotics reduce antibiotic resistance genes and MDR pathogens but do not eliminate them.

Staphylococcus haemolyticus is a reservoir of antibiotic resistance genes in the preterm infant gut

Lisa E. Lamberte, Elizabeth M. Darby, Raymond Kiu, Robert A. Moran, Antia Acuna-Gonzalez, Kathleen Sim, Alex Shaw, John Simon Kroll, Gusztáv Bélteki, Paul Clarke, Heather Felgate, Mark Alexander Webber, Will P. M. Rowe, Lindsay J. Hall, Willem van Schaik

This study identifies Staphylococcus haemolyticus as a common gut colonizer in preterm infants and reveals its role as a reservoir of antibiotic resistance genes through genomic analysis.

Development of the gut microbiota during early life in premature and term infants

Kathleen Sim, Elizabeth A. Powell, Emma Cornwell, John Simon Kroll, Alex Shaw

This study compares gut microbiota development in premature and term infants at six weeks and two years, finding initial differences that converge over time but with lasting associations with clinical factors and allergic conditions.
