    • Rectal cultures from Swedish and Pakistani hospital-delivered newborn infants were analysed regarding the early acquisition of enterobacteria. Swedish infants were delivered vaginally, Pakistani infants were delivered either vaginally or by caesarean section. The Swedish infants were all breast-fed, whereas breastfeeding was incomplete and often started late among the Pakistani infants. Both groups of Pakistani infants were more rapidly colonized with enterobacteria than were the Swedish infants. Cultures from Swedish infants seldom yielded more than one kind of enterobacteria; E. coli and Klebsiella were most frequently isolated. E. coli dominated in both Pakistani groups, but especially caesarean section delivered infants were in addition often colonized with Proteus, Klebsiella, Enterobacter or Citrobacter species. Breastfeeding from the first day of life reduced colonization with Klebsiella/Enterobacter/Citrobacter. The results suggest that environmental exposure, delivery mode and early feeding habits all influence the early intestinal colonization with enterobacteria.

  • Localisation of hyaluronan in the human intestinal wall.
  • 1991
  • Ingår i: Gut. - 0017-5749 .- 1468-3288. ; 32:7, s. 760-2
  • Tidskriftsartikel (refereegranskat)abstract
    • By using biotin labelled proteoglycan core protein and an avidin enzyme system, hyaluronan (hyaluronic acid) was visualised in specimens of human jejunum. Intense staining for hyaluronan was seen in the loose connective tissue of the villi and of lamina propria while the epithelial layer was unstained. The muscularis mucosae showed only faint staining. The accumulation of hyaluronan in the subepithelial layer of the jejunal mucosa indicates that the previously reported high jejunal secretion of hyaluronan is due to passive diffusion from the subepithelial interstitium. The physicochemical characteristics conferred by hyaluronan may be important for the villi function.
