Demand for rainbow trout in our country has increased significantly in recent years, so the industry dedicated to the culture of this species has also increased its number, and those already engaged in this activity have been in need of increase production of farmed trout. The disease enteric red mouth is one of the major diseases affecting the cultivation of trout, causing major economic losses, the causative agent is the bacterium Yersinia ruckeri, which is transmitted from one fish to another by contact and by water . The present study aimed to isolate and characterize phenotypic and molecular strains of Yersinia ruckeri in rainbow trout fish obtained in the center “El Ingenio“ - Huancayo, to increase knowledge of the biology of this disease agent, and relate strains isolated from fish with symptoms of disease, with those isolated from fish without symptoms of disease. This study was to realize at the Fish Farming Center “El Ingenio“ - Junin and laboratory of Molecular Microbiology and Biotechnology of San Marcos, Lima, in the 2010. Fish were collected with symptoms of enteric disease red mouth (EBR) and without symptoms of this, identified through biochemical tests, 34 strains Y.ruckeri presumptive and confirmed by PCR, 30 of them, all strains identified belong to biotype 1. Susceptibility testing was performed antimicrobial resistant strains found oxolinic acid, chloramphenicol, tetracycline, amoxicillin; 4 are reported multiple resistant strains. For molecular genetic analysis techniques used Enterobacterial repetitive intergenic consensus PCR (ERICPCR), repetitive extragenic palindromic PCR (REP-PCR) and PCR extragenic repeating elements (BOX-PCR), determining intraspecific variability in strains isolated from fish with symptoms like fish without symptoms of EBR. Keywords: Enteric redmouth disease (ERM), Yersinia ruckeri, rainbow trout, phenotypic characterization of Y. ruckeri, molecular characterization of Y. ruckeri.
