However, it is not known which adult microbiota members are capable of colonising the caecum of newly hatched chicks. In this study, we therefore orally inoculated chicks with pure cultures of 76 different bacterial isolates originating from chicken caecum on day 1 of life and determined their ability to colonise seven days later. The caecum of newly hatched chickens could be colonised by bacteria belonging to phyla Bacteroidetes, Proteobacteria, Synergistetes, or Verrucomicrobia, and isolates from class Negativicutes (phylum Firmicutes). On the other hand, we did not record colonisation with isolates from phyla Actinobacteria and Firmicutes (except for Negativicutes), including isolates from families Lachnospiraceae, Ruminococcaceae, Erysipelotrichaceae, and Lactobacillaceae. Representatives of genera commonly used in probiotics such as Lactobacillus, Enterococcus, or Bacillus therefore did not colonise the chicken intestinal tract after a single dose administration. Following challenge with Salmonella enterica serovar Enteritidis, the best protecting isolates increased the chicken\u2019s resistance to S. Enteritidis only tenfold, which, however, means that none of the tested individual bacterial isolates on their own efficiently protected chicks against S. Enteritidis.<\/jats:p>","DOI":"10.3390\/microorganisms7120597","type":"journal-article","created":{"date-parts":[[2019,11,22]],"date-time":"2019-11-22T02:49:27Z","timestamp":1574390967000},"page":"597","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Gut Anaerobes Capable of Chicken Caecum Colonisation"],"prefix":"10.3390","volume":"7","author":[{"given":"Tereza","family":"Kubasova","sequence":"first","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miloslava","family":"Kollarcikova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Crhanova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Karasova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darina","family":"Cejkova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alena","family":"Sebkova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jitka","family":"Matiasovicova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcela","family":"Faldynova","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frantisek","family":"Sisak","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0826-1075","authenticated-orcid":false,"given":"Vladimir","family":"Babak","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Pokorna","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Microbiology, Faculty of Veterinary Medicine, University of Veterinary and Pharmaceutical Sciences Brno, 612 42 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alois","family":"Cizek","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Microbiology, Faculty of Veterinary Medicine, University of Veterinary and Pharmaceutical Sciences Brno, 612 42 Brno, Czech Republic"},{"name":"Central European Institute of Technology (CEITEC), University of Veterinary and Pharmaceutical Sciences Brno, 612 42 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Rychlik","sequence":"additional","affiliation":[{"name":"Veterinary Research Institute, 621 00 Brno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"154","DOI":"10.3389\/fcimb.2016.00154","article-title":"Age-related differences in the luminal and mucosa-associated gut microbiome of broiler chickens and shifts associated with Campylobacter jejuni infection","volume":"6","author":"Awad","year":"2016","journal-title":"Front.
