[Morphologic manifestations of intestinal lesions of bacterial and mycotic etiology developing in association with acute respiratory infections].
By means of light and immunofluorescent microscopy the intestines of 34 children were studied, whose bacterial or mycotic enterocolitis most often combined with acute respiratory infections. Intestinal lesions were caused either by virus (sometimes by Mycoplasma), or by bacteria and fungi. Such changes developed in the debilitated children and their course was more severe, than in monoinfections because of the impaired systemic and local immunity, and probably due to formation of viral-bacterial complexes. Viral intestinal lesions were most often caused by a single virus, but not by multiple ones, as in pulmonary infections, which is explained by interferon production and the intensive therapy used. The alternative component in a viral lesion is enhanced due to the presence of lactic acid in the intestine and therefore it is inhibited when acute viral respiratory infection develops against the background of bacterial or mycotic enterocolitis due to dysbacteriosis. Changes in mucosal stroma and intestinal lymphatic system in different infections depend on the duration of the intestinal lesion.
