[The proteolytic activity of the contents of the normal large intestine and in microecological disorders]. / Proteoliticheskaia aktivnost' soderzhimogo tolstoi kishki v norme i pri mikroékologicheskikh narusheniiakh.

The proteolytic (caseinolytic) activity of fecal supernatants obtained from 52 practically healthy children and 220 children with the etiologically undetermined (unclear) diagnosis of gastrointestinal tract dysfunction has been studied. As revealed in this study, in cases of bacteriologically confirmed microecological disturbances in the intestine, accompanied by the activation of opportunistic microflora, the caseinolytic activity of fecal supernatants increases. The determination of the level of the caseinolytic activity of fecal supernatants on solid culture media as a rapid method, specially intended for the diagnosis of dysbiotic states of the gastrointestinal tract, is proposed.
