  • '기생충'하면 가장 먼저 지저분하다, 느리다 등의 생각이 떠오르기 마련이다. 하지만 기생충에 대해 연구하다 보면 어느새 기생충으로부터 낙관주의를 배우게 된다. 어미 기생충이 알이나 애벌레를 아무리 많이 낳아도 그것이 무사히 숙주에 들어가 성충(成蟲)으로 자랄 확률은 아주 적다. 그럼에도 불구하고 기생충은 조급하게 걱정하지 않는다. 오히려 부지런히 제 할 일을 하면서 참고 견딘다. 우리도 기생충의 낙관적인 생활방식을 닮는다면 마음이 조금은 편안해지지 않을까.

  • 생물계에서는 기생충이 숙주의 행동과 생리를 바꾸는 현상이 많이 일어난다. 숙주의 생식에 영향을 미치는 '기생거세'라는 것이 있으니 생식소가 기생충의 칩입을 받아 생식능력을 잃거나 성전환을 하는 등 기이한 현상을 볼 수 있다.

  • Larval morphogenesis and infection rates of Cercaria pectinata Huet were investigated in regards to histological changes and mortality of the hard clam, Meretrix lusoria $(R\ddot{o}ding)$, in Buan located on the Western Coast of Korea. The trichocerous cercariae, Cercaria pectinata, and its sporocysts parasitize mainly in the tissues of goand, digestive gland and gills of the hard clams. One branched sporocyst grows into a great number of cylindrical sporocysts, and a heavily infected clam possesses 2,000 to 5,000 cylindrical spo ro cysts. Each of them produces approximately 30 to 70 germinal cells and cercariae. Of 2,639 clams examined 347 individuals $(13.2\%)$ were found to be infected. The infection rates showed seasonal variations, the rate being highest $(29.6\%)$ in July, and lowest $(2.0\%)$ in March. Whereas, the infection rates did not change significantly with the changes of size class of the shell. No infection was observed in Meretrix petachialis (Lamarck) collected from Myeong-ji, Kimhae Gun located near Busan. In the iefected clams, the gametogenesis (oogenesis and apermatogenesis) did not undergo completely, therefore the heavily infected clam seemed to be castrated. Also the tissues of the digestive gland and gills were compressed by the multiplication of the parasites. When they were kept in aquariums in the laboratory, high mortality has occurred in the infected clams. All of the 60 infected clams died within 35 days.

  • Parasites of freshwater fishes in Cheju-do were studied from May 1989 to April 1990, and incidence of infection in 16 fish species was reported. Protozoan parasites (Trichodina sp., Chilodonella sp., Ichthyophthirius sp., Vorticella sp., Myxidium sp., Myxobolus sp., Henneguya sp:, Ichthyobodo sp., and Trychophrya sp.), water mold (Saproregnia sp.), two monogenes (Dactylogyrus sp. and Gyrodactylogyrus sp.), Trematods, Cestods, Nematods, Acanthocephalas, parasitic copepods(Lernaea sp. and Pseudergasilus sp.) and a Hirudinea were recognized as freshwater fish parasites in Cheju-do. Trichodina sp. showed the highest infection rate (18.3%). Fifty seven individual fishes out of 311 were infected by this parasite. Nematods showed the second highest infection rate (13.5%). Dactylogyrus sp., Acanthocephalas, and Trematods showed the third (4.8%), fourth (4.2%), and fifth (2.6%) infection rate respectively. Of the 16 fish species Cryptocentrus filifer (Gobiidae) showed the highest infection rate. Nineteen fish out of 28 have Trichodina sp., and 14 fish out of 28 have Nematods. Those infection rates were 67.9% and 50.0% respectively. No parasites were collected from the fishes of Gwangryung vally, Dosoon-chun, Gangjeong-chun, and Hyodon-chun.

  • We had reported the infection rates of trematode larvae, Cercaria tapidis and C. harengulae in the gonad tissues of Tapes philippinarum and Solen strictus in the estuary of Kum river, the west coast in Korea in 1980~1982. At the same sites from January 1994 to January 1995, we investigated the variation of the infection rates of these trematode larvae in the two clams. The results are follows. The infection rate of C. tapidis parasitized in T. philippinarum increased in 2.4 times (14.0%) higher than that (5.7%) in 1981. Monthly maxium infection rate was 32.0% in October 1994. Comparing the rate (23.3%) in December 1981, the rate in 1994 showed a higher trend than that in 1981. The mean infection rate of C. harengulae in T. philippinarum showed 2.3% in 1994. Comparing that (5%) in 1980, it showed a decreased rate than that in 1980. And monthly maximum infection infection rate of this clam was 6.7% in May 1994, compared with the rate (19.0%) in March 1980. It appeared furthermore decreased rate in 1994. The mean infection rate of the year of C. harengulae in S. strictus was 6.9% in 1994, while it was 10.2% between 1981 and 1982. It showed a decreased trend in 1994. Monthly maximum infection rate was 23.4% in August 1981, while it was 13.3% in April 1994. It showed a decreased trend in 1994 also. In case of C. tapidis the more large sizes of shell length the more infection rates were higher as same in the investigation in 1980, while in C. harengulae the smaller sizes, the more infection rates showed a higher trend.
