Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are currently no data and very limited knowledge present on the composition of bacterial surviving factors in humans, or on their impact on the human immune system.
As such, 1) the iron status, 2) the microbial biota composition and the 3) siderophore-profile in allergics and non-allergics will be assessed.
