Upper respiratory tract microbiota in health and disease – a minireview

A most common infection is that the upper respiratory tract. The human body is inhabited by millions of microorganisms, most of which enable the proper functioning of some systems and constitute a barrier protecting against harmful external factors. Due to the continuous contact of the upper airway microbiota with the external environment, it may seem to be extremely unstable and very diverse. A number of studies have been conducted that have assessed the effect of various factors on the composition of the upper respiratory tract microbiota. This paper presents a literature analysis which showed that the anatomical area is rich in terms of the microbiota that forms it, and despite the constant changes in many parameters, including physical – very stable.
