中文摘要 | 本所從77年6月至78年6月共檢查144個海產魚類之病例,其中原蟲性疾病佔 77.8%,細菌性及外寄生蟲性各為17.3%、49%。而原蟲性疾病中:以車輪蟲口(48.3%), 海水性自點蟲(35.7%),卵圓鞭毛蟲(20.5%)出現頻率較多;均不具寄生專一性,可感染 不同品種之魚類。海水性自點蟲及卵圓鞭毛蟲均有趨向集中在某些月份內發病,海水性白點 蟲較集中在高水溫期,而卵圓毛蟲較集中低水溫期,使魚體發病。細菌性疾病,以弧菌 (V.anguillarum, V﹒SP),鏈球茵(streptococcus sp.),親水性產氣單胞菌(A. hydrophila) 感染魚體為主,其中弧菌亦較集中於低水溫期間,感染魚體而發病。外寄生蟲性疾病,以單 生類、撓腳類及水姪為主;因該單生類後方固著器下有一小棘群盤,其特徵與LamelIodiscus sp﹒非常相似。血液檢查,均無發現紅血球細胞質內之嗜酸性包涵體。 |
英文摘要 | 144 seawater fish-disease cases were examinated during the period from June 1988 to June 1989 in our Center. These included 77.8% from protozoan diseases, 17.3% and 4.9% from bacteria and extrapatasitic diseases reseases respectively. Major protozoan diseases included 43.8% from Trichodina (Cyclochaeta) sp., 35.7% from Cryptocaryon irritans and 20.5% from Oodinium ocellatum. There is no host specificity in these protozoan diseases, however Crptocaryon irritans and Oodinium ocellatum occurred in certain months of the year and the former favors high water temperature period whereas the latter Oodinium favors low water temperature period and more pathogenic to fishes. The major bacteria disease included Vibrio anguillarum、V. sp. Streptococcus sp and Aeromonas hydrophila. V. anguillarum favors low water temperature period and again more pathogenic to fishes. Major extraparasite included monogenea、copepoda and leech The morpholopy of structure is quite similar to Lamellodiscus sp, however no eosinophilic cytoplasmic inclusion bodies could be found in the RBC from blood examination. |
