우리 나라에 분포하는 스파르가눔의 실험실 내 생활사
Experimental life history of Spirometra erinacei
초록
우리 나라에서 인체감염을 일으키는 스파르가눔의 중간숙주를 파악하고, 각 단계의 유충을 관찰하기 위하여 이 연구를 수행하였다. 실험실에서 키운 물벼룩(Mesocyclops leuckarti, Eucyclops serrulatusi Moina sp.)과 참개 구리의 올챙이를 각 단계의 유충에 접촉 감염시키고, 다음 단계의 유충을 얻어 다른 숙주에 감염시켰다 각 시기에 있는 유충의 발육과 형태를 관찰한 바 다음의 결과를 얻었다. 1. 실험적으로 스파르가눔을 개와 고양이에 감염시켜 얻은 Spirometra의 충란을 증류수에서
The complete life cycle of Spirometra erinacei has been experimentally maintained in the laboratory. The cyclops were reared as the first intermediate host, and the tadpoles of Rana nigromaculata as the second intermediate host. ICR mice were used as another second host. The experimental definitive hosts were dogs and cats. Maturation and hatching of the eggs took 8 to 14 days by incubation at 29℃. The coracidium measured 43.8×36.9㎛. Mesocyclops leuckarti and Eucyclops serrulatus were susceptible to the coracidial infection. The procercoids older than 5 days in the cyclops had minute spines at the anterior end, calcium corpuscles in the body parenchyme and the cercomer at the posterior end. Procercoids 10 to 20 days old were infective to tadpoles, and 15 or 21 day old worms could infect the mice. The plerocercoids from the tadpoles at 15 days after experimental infection were pear-shaped and shorter than 1 mm in the length and were infective to mice. Fifteen to 18 days after experiMental inoculation of plerocercoids to dogs or cats, the adult worms began to produce eggs. One life cycle from egg to egg needed 48 to 67 days in the laboratory. The morphology of larval or adult worms was compatible with the description of Spirometra erinacei.
