Pathophysiology of Cultured Tiger Puffer Takifugu rubripes Suffering from the Myxosporean Emaciation Disease

摘要: The present study suggests that the myxosporean emaciation disease by enteric infection of Enteromyxum leei disrupts intestinal water uptake tiger puffer Takifugu rubripes. This idea is based on a significant negative correlation between plasma chloride concentration and condition factor in diseased fish, significantly higher osmolarity major ion con- centrations fluid infected fish than healthy control fish. Additionally, surgical ligation junction stomach intestine resulted 24% drop body weight within 50 h, lower content white muscle (operated 74 ± 0.5%; sham-operated 82 1%). However, vitro isolated sacs was not different Meanwhile, hepatic function appeared to be impaired as evidenced hepato-somatic index (control 8.7 0.8%; 2.7 0.8%). Plasma activities LDH, AST ALT were all We propose rapid loss mainly due osmoregulatory failure but probably malnutrition also involved pathogenesis.
