[0002] Streptococcus (Streptococcus spp.) is a Gram-positive bacterium widely distributed in nature. It is one of the important pathogens of humans and is also an important pathogen of other vertebrates including pigs, cattle, fish, etc.; Streptococcus agalactiae is It is considered to be the only streptococcus with group B specific antigen. In recent years, streptococcus agalactiae has infected a variety of seawater and freshwater fish and caused a variety of diseases. Streptococcus agalactiae has been given to tilapia in Asia Aquaculture has caused serious harm; although some medicines and antibiotics are also used to treat Streptococcus agalactiae of tilapia in the prior art, drug resistance and antibiotic abuse caused by long-term use have also caused serious harm to the aquaculture industry. It is urgent to seek a research that can prevent marine and freshwater aquaculture diseases without causing side effects on aquaculture

Abstract
The invention belongs to the technical field of aquaculture preparations, and discloses a composition for preventing streptococcicosis. The composition is prepared from the following components in percentage by weight: 10-15% of the root of Chinese pulsatilla, 7-15% of honeysuckle flwores, 7-15% of isatis root, 10-20% of houttuynia cordata, 20-40% of black soya beans, and 0-20% of smoked plum. After the composition for preventing streptococcicosis is added into a feed for tilapia mossambica, the highest immune protective rate for the tilapia mossambica achieves 83.14%, the survival rate of the tilapia mossambica is 88.67%, and the composition has practical and wide application values.
