<string language="fre"><![CDATA[Avian eggs
possess very efficient and orchestrated systems to protect the embryo during
incubation, until hatch. Although the internal components of the egg are
assumed to be sterile, the surface of the eggshell is covered by microbes
(essentially bacteria) that may contribute to prevent eggshell colonization by
pathogenic bacteria, through direct inhibition and/or competitive exclusion.
The composition of the eggshell microbiome is a heritage from both maternal
microbiota (caeca/faeces) where the egg meets caecal secretions in the cloacal
segment during oviposition, and from the nesting environment (contaminated
litter/feathers and air environment including dust). At laying time, the egg
surface is still moisturized, but will progressively dehydrate during
incubation. The surface characteristics of the egg, the loss of the moisture
layer and the presence of antimicrobial molecules composing the cuticle are
likely to dictate the bacterial communities that will survive on the surface of
the eggshell. Although the literature on the composition of the eggshell
microbiome of eggs originating from current commercial chicken hens is quite
sporadic, this talk aims to provide an overview of the bacterial communities
that colonize the chicken eggshell surface, and will discuss the role of the
eggshell microbiota as the first barrier against pathogenic bacteria.
