Identification and Relatedness of B. longum Strains
(A) Sampling scheme and strain identification within individual breast-fed (BF1-BF5) and formula-fed (FF1-FF3 and FF5) infants based on average nucleotide identity values (ANI). The three levels of shading mark different dietary phases: pre-weaning, weaning, and post-weaning.
(B) Relatedness of B. longum strains based on core proteins. Colored strips represent isolation period (pre-weaning, weaning, and post-weaning) and isolation source (individual infants), respectively.
