Abstract

Preterm infants exhibit different microbiome colonization patterns relative to full-term infants, and it is speculated that the hospital room environment may contribute to infant microbiome development. Here, we present a genome-resolved metagenomic study of microbial genotypes from the gastrointestinal tracts of infants and from the neonatal intensive care unit (NICU) room environment. Some strains detected in hospitalized infants also occur in sinks and on surfaces, and belong to species such as Staphylococcus epidermidis, Enterococcus faecalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae, which are frequently implicated in nosocomial infection and preterm infant gut colonization. Of the 15 K. pneumoniae strains detected in the study, four were detected in both infant gut and room samples. Time series experiments showed that nearly all strains associated with infant gut colonization can be detected in the room after, and often before, detection in the gut. Thus, we conclude that a component of premature infant gut colonization is the cycle of microbial exchange between the room and the occupant.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some authors set a cut-off of less than or equal to two SNV differences, while others set an ANI value of greater than 98% for isolates to be considered to come from the same natural strain.

    “Some authors set a cut-off of less than or equal to two SNV differences [58], while others set an ANI value of greater than 98% [59] for isolates to be considered to come from the same natural strain.”

    From Genomic Characterization of Lactiplantibacillus plantarum Strains: Potential Probiotics from Ethiopian Traditional Fermented Cottage Cheese (2024) · cites this paper as [59]

    The Results section (“Organisms found in the infant gut have room reservoirs”) reports that a prior study treated two near-complete genome bins as the same strain when they shared >98% ANI across 95% of the bin. But this paper’s own strain-transfer analysis (“Evidence of strain transfer among infants and rooms”) uses 99.999% ANI, and the reported >98% criterion concerns genome bins rather than isolates. The ≤2-SNV criterion is attributed to a different citation, not this source. (LLM, conf=0.88)

  • The lower fraction of microbes shared in non-westernized microbiomes is not due to technical artifacts and may be partly explained by higher microbiome richness, possibly due to increased acquisition from other environmental or family sources.

    “suggesting the lower fraction of microbes shared in non-westernized microbiomes is not due to technical artifacts and may be in part explained by a much higher microbiome richness, possibly due to increased acquisition of microbiome members from other environmental or family sources.42,43”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
