Technical Abstract: Streptococcus iniae and S. agalactiae are important emergent-epizootic pathogens which affect many fish species world-wide, especially in warm-water regions. Further, these Gram-positive bacteria cause significant economic losses in marine and freshwater aquaculture systems with an estimated loss in the hundreds of millions of dollars, annually. Infection results in septicemia and neurotropic disease, with mortality rates between 30 to 50%. Streptococcal disease is very difficult to control because these pathogens are resistant or become resistant to most chemicals and drugs. The aim is to present a review of current information on fish streptococcosis including aspects of epidemiology, diagnosis, pathogenesis, and control measures including vaccinology in farmed tilapia.
