Airway Microbiota and Allergic Diseases: Clinical Implications

Bronchial Asthma is an airway disease with variable degrees of bronchial mucosal inflammation and intermittent episodes of airway obstruction and bronchial hyperesponsivness. That asthma is a syndrome consisting of different phenotypes has been recognized for a long time by clinicians [1]. New evidence indicates that the composition of airway microbiota differs in states of health and disease. Different chronic airway diseases had been related to changes in microbiota due to various factors which could affect severity of symptoms and even response to treatment [2]. Micro biome may be one of the protective factors against asthma in early life [3].
