摘要

The bacteriological examination conducted on 10 counts of trout belonging to a trout farm bordering Cluj county, led to the isolation of atypical strains of Aeromonas salmonicida (A. salmonicida subsp. achromogenes). This subspecie is isolated for the first time in our area of activity and it was identified with the help of API 20 E galleries and through some supplementary tests like: catalyses test, oxidase test, insemination at 25 and 37C, the mobility test and hemolytic activity. The isolated strain of A. salmonicida subsp. achromogenes was sensitive to: Enrofloxacin, Florfenicol, Nalidixic acid., Oxytetracycline, resistant to Erythromycin, Amoxicillin Clavulanate and Lincomycin.
