水產研究(1993年創刊)-桃園及新竹地區養殖吳郭魚法朗西斯氏菌感染症之調查研究
主題: 桃園及新竹地區養殖吳郭魚法朗西斯氏菌感染症之調查研究
摘要(中):
近年來受到天氣異常變化及水源品質不穩定影響,臺灣養殖吳郭魚常在疾病感染時爆發大量死亡,其中又以法朗西斯氏菌 (Francisella spp.) 之感染最為嚴重,造成養殖業者鉅大之經濟損失。法朗西斯氏菌感染症 (Francisellosis) 早年又被稱為類立克次體感染症 (Rickettsia-like organism infection),現已統一將此病原正名為法朗西斯氏菌。本病被報告發生於歐洲、南北美洲及亞洲 (包括臺灣) 等不同國家,可感染野生魚類和多種養殖魚種,造成水產養殖業嚴重的經濟損失。本研究於2009 ~ 2011年針對桃園及新竹地區養殖吳郭魚法朗西斯氏菌感染症於不同季節 (溫度)、臨床病變及水體傳播之關連性做一深入探討。研究結果顯示桃園及新竹地區養殖吳郭魚感染之法朗西斯氏菌,無法於一般人工培養基上分離培養,應用聚合酶鏈鎖反應檢測及基因序列鑑定其病原,証實其為F. noatunensis subsp. orientalis 所感染。發病場經由水排放會導致下游埤圳養殖池皆會感染,並於3 ~ 4月及10 ~ 11月進入發病高峰期,因此時溫度約在23 ~ 27 ℃,最適於法朗西斯氏菌之繁殖,易導致疾病之爆發。

摘要abstract(英): In recent years, climate changes accompanied by unstable water quality have often caused outbreaks of diseases, followed by mass mortality of farmed tilapia in Taiwan. Francisellosis was previously known as piscirickettsiosis (rickettsia-like organism infection), but now the pathogens involved have been renamed to Francisella spp. The disease has been reported as occurring in different countries in Europe, North and South America, and Asia (including Taiwan), causing infections among a variety of wild fish and farmed fish, and resulting in serious economic losses to the aquaculture industry. This paper investigated the francisellosis infections of farmed tilapia in Taoyuan and Hsinchu areas during different seasons, considering clinical signs and the relation of water transmission from 2009 to 2011. The results showed that Francisella spp. found in Taoyuan and Hsinchu areas cannot be isolated on common artificial media. The pathogen can be identified as F. noatunensis subsp. orientalis by polymerase chain reaction and DNA sequence assay. Downstream pools may be infected by water transmission from the drainage of upstream farms. There are two peak periods for francisellosis outbreaks, March-April and October-November, due to these periods are the most suitable temperature for the reproduction of F. noatunensis subsp. orientalis.
