Abstract

This study investigated the distribution of scuticociliates in the intestine, spleen, kidney, testis, brain, pericondrial bone and muscle layer of the tiger puffer, Takifugu rubripes, infected with scuticociliates. Scuticociliates were infiltrated in the connective tissues of the outer layer of the intestine, spleen, kidney, testis, brain, pericondrial bone and muscle layer. In brain, membranous tissue and optic lobe cortex separation were accompanied by the infection of scuticociliates. Other internal tissues and organs did not show any lesions expect for heavy deposition of hemosiderin in spleen.

스쿠티카섬모충에 감염된 자주복의 장, 비장, 신장, 정소, 뇌, 연골 그리고 육질부에 충체의 분포를 조사하였다. 실험어는 사조 CS(주)에서 사육중인 자주복 중 스쿠티카섬모충에 감염된 자주복을 이용하였다. 스쿠티카섬모충은 장, 비장, 신장, 정소, 뇌, 연골, 육질부의 기관을 덮는 결합조직에 분포하고 있다. 뇌에 감염되었을 때 막성조직과 시엽피질 사이가 벌어지는 증상이 있었다. 비장에서 hemosiderin이 과다 침적되는 증상을 제외한 다른 내부 조직과 기관에서는 병리적 증상을 볼 수가 없었다.
