摘要：
Predominance of gram-negative bacteria belong ing to the class Gammaproteobacteria on the intestinal mucosa of pike was determined. The morphophysiological features of the isolated microorganisms suggest that they belong to symbiotic intestinal microflora. The morphological characteristics of the intestinal symbiotic microflora of pike include the formation of the capsule, pseudovacuoles, and spheroplastic forms of cells. The bacteria that were found can produce hydrolytic enzymes and possess persistence properties. The morphophysiological features that were found contribute to the adaptation of bacteria to environmental conditions and indicate that the intestinal microflora offish is autochthonous.
