The Claim
The source of colibactin-producing bacteria in infants is not established, as low parental carriage rates and minimal detection in NICU environmental samples challenge the assumption that vertical transmission at birth is the primary route of colonization.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists do not yet know where infants get colibactin-producing bacteria, because these bacteria are rarely found in parents or in hospital environments, which suggests they may not be passed from mother to baby during birth as previously thought.
See the scientific wording
The source of colibactin-producing bacteria in infants remains unknown, as parental carriage rates are low and environmental samples from NICUs show minimal detection, challenging the assumption that vertical transmission at birth is the primary route of colonization.
What the research says
1 studyStudy: Colibactin genes are highly prevalent in the developing infant gut microbiome
Scientists found that more than half of babies have these bacteria in their guts, even though their parents rarely carry them and the hospital environment doesn’t seem to be the source. This means we still don’t know how babies get them.
