The etiology of respiratory diseases (RD) is represented by viral and bacterial pathogens [1]. Obviously, viral infections cause most of respiratory diseases in children, while antibiotic treatment is at least useless and often considered inefficient due to a multitude of adverse events. Antibiotics may cause allergic reactions, impair biocenosis of the respiratory tract and colonization of its mucous membranes with unwanted, often intestinal, flora. The greatest danger, however, is the development of overall antibiotic resistance of microbial flora which currently is one of the most serious public healthcare problems [2]. At the same time, bacterial infection, in case of late detection and inadequate treatment, poses a greater risk for serious complications and therefore requires reasonable prescription of systemic antibiotic therapy.
