Identification and genetic characterization of Streptococcus iniae strains isolated from diseased fish in China.

The article discusses the Streptococcus Iniae strains isolated from diseased fish in China and its identification and genetic characterization. It determines the fishes' genetic diversity by pulsed field gel electrophoresis. It mentions that mortalities due to streptococcal infections occurred in seawater cage cultured fish including tilapia. It studies the anatomy of the diseased fishes including the brain, spleen and kidney tissues. It conducts bacterial identification using biochemical and phenotypical tests.
