Originální abstrakt

In this study we characterised the development of caecal microbiota in egg laying hens over their commercial production lifespan, from the day of hatching until 60 weeks of age. Using pyrosequencing of V3/V4 variable regions of 16S rRNA genes for microbiota characterisation, we were able to define 4 different stages of caecal microbiota development. The first stage lasted for the first week of life and was characterised by a high prevalence of Enterobacteriaceae (phylum Proteobacteria). The second stage lasted from week 2 to week 4 and was characterised by nearly an absolute dominance of Lachnospiraceae and Ruminococcaceae (both phylum Firmicutes). The third stage lasted from month 2 to month 6 and was characterised by the succession of Firmicutes at the expense of Bacteroidetes. The fourth stage was typical for adult hens in full egg production aged 7 months or more and was characterised by a constant ratio of Bacteroidetes and Firmicutes formed by equal numbers of the representatives of both phyla.

Český abstrakt

V této studii jsme charakterizovali vývoj mikroflóry ve střevech nosnic ode dne vylíhnutí až do uplynutí 60 týdnů věku. SekvenovánímV3 / V4 variabilních oblastí 16S rRNA genů pro charakterizaci mikroflóry, jsme byli schopni definovat 4 různé stupně vývoje mikroflóry. První fáze trvala po první týden života a byla charakterizována vysokou prevalencí Enterobacteriaceae (kmen Proteobacteria). Druhá etapa trvala od 2. týdne do 4. týdnu byla charakterizována téměř absolutní dominancí Lachnospiraceae a Ruminococcaceae (oba kmen Firmicutes). Třetí etapa trvala od druhého do šestého měsíce a byla charakterizována řadou Firmicutes na úkor Bacteroidetes. Čtvrtá etapa byla typická pro dospělé slepice a byla charakterizována konstantním poměrem Bacteroidetes a Firmicutes tvořenou stejného počtu zástupců obou kmenů.
