Contact with adult hens affects the composition of skin and respiratory tract microbiota in newly hatched chicks

Popis výsledku v původním jazyce

Chickens in commercial production are hatched in hatcheries without any contact with their parents and colonization of their skin and respiratory tract is therefore dependent on environmental sources only. However, since chickens evolved to be hatched in nests, in this study we evaluated the importance of contact between hens and chicks for the development of chicken skin and tracheal microbiota. Sequencing of PCR amplified V3/V4 variable regions of the 16S rRNA gene showed that contact with adult hens decreased the abundance of E. coli, Proteus mirabilis and Clostridium perfringens both in skin and the trachea, and Acinetobacter johnsonii and Cutibacterium acnes in skin microbiota only. These species were replaced by Lactobacillus gallinarum, Lactobacillus aviarius, Limosilactobacillus reuteri and Streptococcus pasterianus in skin and tracheal microbiota of contact chicks. Lactobacilli can be therefore investigated for their probiotic effect respiratory tract in a future. Skin and respiratory microbiota of contact chickens was also enriched for Phascolarctobacterium, Succinatimonas, Flavonifractor, Blautia and [Ruminococcus] torque though, since these are strict anaerobes from the intestinal tract, it is likely that only DNA from non-viable cells was detected for these taxa.
