Streptococcosis in cultured turbot, Scopthalmus maximus (L.), associated with Streptococcus parauberis

Abstract Several strains of Garm‐positive short rod (coccibacilli)‐shaped bacteria were isolated from diseased cultured turbot, Scophthalmus maximus (L.), in the North of Spain with lesions and signs of Spain with lesions and signs of streptocecosis. The α‐haemolytic streptoceoccus‐like organisms from diseased turbot were identified by physiological, biochemical and 16S rRNA gene sequence analysis as Streptococcus parauberis. This is the first report of S. parauberis associated with fish disease.
