US Patent Office Full Record
New Fish Vaccine for Streptococcus iniae
ARS researchers have developed a new vaccine against Streptococcus iniae, an emerging bacterial pathogen in cultivated tilapia, hybrid striped bass, rainbow trout, yellowtail, eel, and turbot. Worldwide, streptococcal infections are reported in 22 fish species, both cultured and wild, and causes $150 million a year in losses. This disease is recognized as one of the most problematic bacterial pathogens in intensively cultured fish and wild fish. Signs of the disease in fish include erratic swimming, whirling motion at the surface of the water, darkening of the skin, blindness, popeyes, and small lesions on the body, fins, and anus.
Antibiotic treatments currently used to control the disease in fish suppress strep disease signs, but doesn't completely eliminate the bacterium from treated fish. The vaccine, which can be given by injection or possibly by immersion, provides protection against mortality and disease for at least five months.
