| description | The present paper reports the presence of Flavobacterium psychrophilum such as pathological agent of "bacterial disease of cold water" on juvenile Onchorhynchus mykiss "rainbow trout" from El Ingenio fish farm, Junín (3250 m). The ulceration of the dorsal area was the most frequent macroscopic external injury as well the localized blackening of the skin. Internally there was a marked splenomegaly, pallor of the liver, kidney and gills, inflammation of the intestine and ascitic fluid in the peritoneum. Internal hemorrhage was not detected. 29 strain Gram negative were isolated in Modified Cytophaga Agar (MCA) (Anaker & Ordal, 1959), which according to the phenotypic characterization and the biochemical tests 9 were considered as F. psychrophilum. Tests of antibiotic susceptibility showed high sensitivity of this strains to Gentamicin, Ceftazidine, oxytetracycline, Norfloxacine, furazolidone, Ciprofloxacine and Cefoxitine |

La lesión macroscópica externa más frecuente fue la ulceración profunda de la región dorsal del pez acompañado de un ennegrecimiento localizado de la piel. Internamente se observó una marcada esplenomegalia, palidez del hígado, riñón y branquias, inflamación del intestino y acumulación de líquido ascítico en el peritoneo. No se detectó hemorragia interna. En Agar Cytophaga Modificado (ACM) según Anaker & Ordal (1959) fueron aisladas inicialmente 29 Gram negativas, de las cuales según la caracterización fenotípica y pruebas bioquímicas 9 fueron consideradas como F. psychrophilum. Pruebas de susceptibilidad antibiótica mostraron alta sensibilidad de las cepas a Gentamicina, Ceftazidina, oxitetraciclina, Norfloxacina, furazolidona, Ciprofloxacina y Cefoxitina.
