    Gut bacteria are rarely shared by co-hospitalized premature infants, regardless of necrotizing enterocolitis development

    Tali Raveh-Sadka et al.
    Rapid yet comprehensive, genome-resolved analysis of fecal samples from premature infants reveals little overlap in strain composition of gut microbial communities, despite co-hospitalization, and suggests the existence of barriers to strain dispersal.

    Experimental evaluation of the importance of colonization history in early-life gut microbiota assembly

    Inés Martínez et al.
    Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.
