The aim of this study was to determine the presence of the agent Yersinia ruckeri in fish farm “Eden“ and to identify and classify anatomical histopathological lesions in tissues of rainbow trout (Oncorhynchus mykiss) of fish farm “El Eden“ located Conception in the province at 3400 m. in Junín region. From the cultured organs was isolated 11 strains gram negative, 9 strains belonging to the Enterobacteriaceae, of which 3 were characterized by biochemical tests as Yersinia ruckeri and were similar to those reported for the first time in Idaho. As was observed macroscopic lesions unilateral exophthalmos 8/30 (26.66%), melanosis 4/30 (13.33%), liver pale 18/30 (60.00%), liver congested 3/30 (10.00%), liver petechiae 15 / 30 (30.00%), pale gills 4/30 (13.33%), gills hyperemic 9/30 (30%) and the study evidenced hiatopatologico spleen congestion in 14/30 (46.66%), hyperplasia of the apex of the gills 12 / 30 (40.00%), cecal villus hyperplasia 5/30 (16.66%), heart spores ictiofonus in 6/30 (20.00%), stomach mucosa necrosis in 4/30 (13.33%), hepatic congestion 4/30 ( 13.33%), hyperplasia in the small intestinal mucosa 9/30 (38.88%) and renal tubular regeneration 9/30 (30%). Strains were isolated from Y. ruckeri and tissue injuries are consistent with infection however the frequency of isolation is low and there are different from other bacteria that have been isolated Enterobacteriaceae bacteria including Gram positive and do not know what role they play in disease of rainbow trout. Keywords: Yersinia ruckeri, anatomical and histopathological, rainbow trout, disease of “enteric red mouth”
