Journal ArticleDOI
The Potential of Gut Commensals in Reinforcing Intestinal Barrier Function and Alleviating Inflammation
Kaisa Hiippala,Hanne Jouhten,Aki Ronkainen,Anna Hartikainen,Veera Kainulainen,Jonna Jalanka,Reetta Satokari +6 more
TL;DR: The latest findings considering the beneficial effects of the promising commensals across all major intestinal phyla are summarized, including the already well-known bifidobacteria, which use extracellular structures or secreted substances to promote intestinal health.
Journal ArticleDOI
Intestinal Microbiota And Diet in IBS: Causes, Consequences, or Epiphenomena?
Mirjana Rajilić-Stojanović,Daisy Jonkers,Anne Salonen,Kurt Hanevik,Jeroen Raes,Jonna Jalanka,Willem M. de Vos,Chaysavanh Manichanh,Natasa Golic,Paul Enck,Elena Philippou,Fuad A. Iraqi,Gerard Clarke,Robin C. Spiller,John Penders +14 more
TL;DR: This review describes pathways (mechanisms) by which diet components, via the microbial fermentation, could trigger IBS symptoms and suggests recommendations for future studies that would enable elucidation of the role of diet and microbiota and how these factors may be (inter)related in the pathophysiology of IBS.
Journal ArticleDOI
Effects of bowel cleansing on the intestinal microbiota
Jonna Jalanka,Anne Salonen,Jarkko Salojärvi,Jarmo Ritari,Outi Immonen,Luca Marciani,Penny A. Gowland,Caroline L. Hoad,Klara Garsed,Ching Lam,Airi Palva,Robin C. Spiller,Willem M. de Vos +12 more
TL;DR: The results suggest that the bowel cleansing using two separate dosages introduces fewer alterations to the intestinal microbiota than a single dose and hence may be preferred in clinical practice.
Journal ArticleDOI
The composition of the perinatal intestinal microbiota in cattle
Mohammad Alipour,Jonna Jalanka,Tiina Pessa-Morikawa,Tuomo Kokkonen,Reetta Satokari,Ulla Hynönen,Antti Iivanainen,Mikael Niku +7 more
TL;DR: 16S rDNA data indicates the existence of a diverse low-abundance microbiota in the newborn rectal meconium and mucosa, and suggests that mammals are seeded before birth with a diverse microbiota, but the microbiota changes rapidly in the early postnatal life.
Journal ArticleDOI
Long-term colonisation with donor bacteriophages following successful faecal microbial transplantation
Lorraine A. Draper,Feargal J. Ryan,Muireann K. Smith,Jonna Jalanka,Eero Mattila,Perttu Arkkila,R.P. Ross,Reetta Satokari,Colin Hill +8 more
TL;DR: Investigating viral transfer following FMT revealed that engraftment of individual bacteriophages was dependent on specific donor-recipient pairings, and multiple recipients from a single donor displayed highly individualised virus colonisation patterns.
