説明
<p>Bifidobacterium bifidum OLB6378 (OLB6378) was selected as a strain that enhances the production of secretory immunoglobulin A (IgA) in vitro. This ability of non-live OLB6378 has been shown by a clinical trial in preterm infants. In the present study, we examined whether non-live OLB6378 also enhances the production of secretory IgA, even in full-term infants. One hundred full-term infants were allocated to receive formula with (BbF group, 49 infants) or without non-live OLB6378 (PF group, 51 infants). Breastfeeding was prioritised, so infant formula was used for infants with breastfeeding difficulties. The intervention was initiated by five days of age. The faecal IgA concentration and OLB6378 level were determined at one, two, four, and eight weeks of age. Faecal IgA in the BbF group (1.04 ± 0.47 mg/g of faeces, n=45) was significantly higher than that in the PF group (0.85 ± 0.42 mg/g of faeces, n=49) at four weeks of age (p=0.047). OLB6378 was not detected in faeces at any age. This indicated that production of secretory IgA in full-term infants may also be enhanced by non-live OLB6378 intake.</p>
