Fish Franciscellosis

Main Article Content

Sumrarn Bunnajirakul


Fish franciscellosis was classified as an important emerging bacterial pathogen. Prevalence of this disease was found in various species such as tilapia, which were reared in global   area included Thailand. High mortality rates have caused significant economic losses. Clinical sign in infected fish was ataxia, anorexia, anemia and exophthalamos. Multifocal white nodules were found in anterior and posterior kidney, spleen, concurrent with enlargement of kidney and spleen. Considered carefully to treat Franciscellosis. Vaccine must be developed for disease prevention.
