Streptococcus iniae Whole Genome Sequencing. Streptococcus iniae IUSA1

Streptococcus iniae, beta-haemolytic Gram-positive cocci, non motile, catalase negative. Has become one of the most serious aquatic pathogens in the last decade with severe economic losses in aquaculture farms. At least 30 species of fish have been documented to be infected by S. iniae. The most prominent lesions were meningoencephalitis and multifocal infiltration of macrophage cells in the kidney and spleen. Can cause serious zoonotic infections in humans injured while handling diseased fish. Streptococcus iniae is able of crossing the blood-brain barrier as free bacteria or associated with monocytes or phagocytes.
