New paper on importance of contact between adult hen and newly hatched chicks for the development of skin and repsiratory tract microbiota

A new paper from our production has been accepted for publication in the Poultry Science. This paper introduces microbial composition of skin and tracheal microbiota and further develops importance of contact between a hen and newly hatched chickens for the development of skin and respiratory tract microbiota of chickens. Many bacteria of gut origin were detected as part of skin and trachea microbiota but since we used DNA sequencing to determine microbiota composition, this was likely only a DNA from no longer viable gut anaerobes. On the other hand, Lactobacilli and Streptococci belonged among likely vital bacteria which were common in skin and tracheal microbiota of chicks in contact with adult hens. Cutibacterium acnes represented another taxon common in skin and respiratory tract microbiota. Finally, Clostridium disporicum and Clostridium perfringens were common in skin microbiota but only rarely entered respiratory tract.
