Abstract
Pleistophora disease is well known as microsporidiosis at eel cultural farms in Korea in recent years. Major objects of this study were to undertake the induction of Pleistophora infection experimentally and to carry out histopathological investigation from December 1984 to June 1986. Experimental infection of Pleistophora spores into young eels was carried out by oral and immersed administration. Both methods induced the same symptom successfully as that in naturally occurring diseased fish. Remarkable whitish lesions developed mainly on the body surface around the abdomen when orally administrated. On the other hand, they were scattered over the whole body when administrated through immersion. Histopathological investigation revealed that some cysts in the muscle were observed 21 days after administration. Spores were developed within the cyst. Each sporont has undergone several nuclear divisions to form a pair of multinucleate cells (Sporoblasts) enclosed within a common coat (Pansporoblast). All stages were surrounded by cyst. The cysts were destroyed and mature spores were scattered in the muscle.
전국양만장(全國養鰻場)에 pleistophora포자충(胞子蟲)이 기생(奇生)하여 상당한 피해(被害)를 입고 있는 실정(實情)이다. Pleistophora증(症)에 관(關)한 기초연구(基礎硏究)로서 감염방법(感染方法)과 감염량(感染量), 감염율(感染率)의 관계(關係) 및 병리조직학적(病理組織學的) 관찰(觀察)을 검토(檢討)한 것으로 결과(結果)는 다음과 같다. 1. Pleistophora anguillarum 포자(胞子)를 경구감염(經口感染)시키거나 침지감염(沈漬感染)시킨 결과(結果), 모두 감염(感染)이 성립(成立)되었다. 경구감염(經口感染)의 경우 포자수(胞子數)
