The increase in the number of acute respiratory infections in children, accompanied by airway obstruction, often leads to the development of stenotic laryngotracheitis. The primary factors are respiratory viruses, and bacterial flora often joining together, changing the type of the disease which is determined by its outcome. Exposure to infectious agents in the body contribute to the development of chronic infectious diseases of the respiratory tract in children, resulting in damages to the ciliary epithelium and weakening of its connection with the basal cells and the basement membrane. This, in turn, facilitates the penetration of allergens and other inflammation stimulants into submucosal tissue.

We have studied the state of the microbial landscape of the mucous membranes in the upper respiratory tract in 275 patients with stenosing laryngotracheitis; they are children aged 6 months to 5 years. All patients were divided into 2 groups: group 1 included 122 children with primary stenosing laryngotracheitis (PSLT); group 2 were 153 patients with recurrent stenosing laryngotracheitis (RSLT).  We noted that the most common mucosal lesion of germs in all age groups falls on Staphylococcus aureus. It has been established that the nasopharynx microbial defeat is found twice as often at RSLT than at PSLT. In older children with RSLT, oropharynx was frequently a complex association of pathogens.
