条斑紫菜拟油壶菌病的初步研究 总被引:1,自引:0,他引:1
1960年新崎盛敏首先报道了寄生在紫菜叶状体细胞内的病原菌是壶状菌Olpidiopsis sp.,之后不少学者对这种病害的病症、发生情况及环境条件等进行了较深入的调查研究。其中右田清治在"养殖紫菜的壶状菌病"以及"紫菜的病害"中较详细描述了该病的病症、病原菌的 相似文献

福建省某水产养殖场养殖的种用真鲷(Pagrosomus major)于1989年3月发生了一种以鳞片脱落、鳍基部出血为主要症状的疾病,从病死真鲷体内分离到一株弧菌,其生化特性、培养特性、致病性与鳗弧菌基本一致,抗原性与鳗弧菌相同,因此认为这次真鲷疾病是由鳗弧菌引起的真鲷弧菌病。 相似文献

Lymphocystis disease is a prevalent, non-fatal disease that affects many teleost fish and is caused by the DNA virus lymphocystis disease virus (LCDV). Lymphocystis-like lesions have been observed in yellow perch, Perca flavescens (Mitchell), in lakes in northern Alberta, Canada. In an effort to confirm the identity of the virus causing these lesions, DNA was extracted from these lesions and PCR with genotype generic LCDV primers specific to the major capsid protein (MCP) gene was performed. A 1357-base pair nucleotide sequence corresponding to a peptide length of 452 amino acids of the MCP gene was sequenced, confirming the lesions as being lymphocystis disease lesions. Phylogenetic analysis of the generated amino acid sequence revealed the perch LCDV isolate to be a distinct and novel genotype. From the obtained sequence, a real-time PCR identification method was developed using fluorgenic LUX primers. The identification method was used to detect the presence/absence of LCDV in yellow perch from two lakes, one where lymphocystis disease was observed to occur and the other where the disease had not been observed. All samples of fin, spleen and liver tested negative for LCDV in the lake where lymphocystis disease had not been observed. The second lake had a 2.6% incidence of LCD, and virus was detected in tissue samples from all individuals tested regardless of whether they were expressing the disease or not. However, estimated viral copy number in spleen and liver of symptomatic perch was four orders of magnitude higher than that in asymptomatic perch. 相似文献

绿斑病(Green spot disease)是一种常见的海区栽培条斑紫菜(Pyropia yezoensis)病害,在整个紫菜栽培期间都可能发生,以每年11~12月份最为严重,主要出现在幼叶期和成叶期。首先,在叶状体上出现红色或淡红色小斑,而后逐渐转变为绿色,病斑继续扩展,在叶状体表面形成若干孔洞,后期几乎整个藻体变绿。本研究对日照地区患绿斑病的条斑紫菜进行病原菌分离纯化,得到5株优势菌(编号为Y1~Y5),人工回感实验结果显示,Y1可以引起健康条斑紫菜发生绿斑病。对Y1进行了生理生化检测、16S rRNA、dnaA和dnaN基因序列分析,确定病原菌为海洋假交替单胞菌(Pseudoalteromonas marina)。对绿斑病的发病进程进行了观察,并检测了培养温度、海水比重和养殖密度等环境因子对绿斑病发生的影响,结果显示,高温和高密度养殖会加速绿斑病病情的发展,海水比重为1.022时,绿斑病发病较严重。本研究确定了一株引起条斑紫菜绿斑病的病原菌,并分析了部分理化因子对感染的影响,为条斑紫菜绿斑病的防控提供了基础数据。 相似文献

Oxygen uptake in the Antarctic teleost Pagothenia borchgrevinki. Limitations imposed by X-cell gill disease 总被引:1,自引:0,他引:1
Fish in a population of Pagothenia borchgrevinki in McMurdo Sound, Antarctica, are affected by a gill disease (X-cell disease) which causes tissue hyperplasia that results
in a decreased gill surface area and an increased water/blood diffusion distance. P. borchgrevinki acquires 95% of its oxygen via the gills, but damage to the gills by X-cell disease did not affect this function. There was
no compensatory shift to cutaneous respiration. X-cell disease reduced the ability for oxygen uptake at low ambient PO
2 and the decreased uptake was related to the extent of the disease. O
2 max was greatly reduced in X-cell affected fish and substantially reduced their aerobic potential. This effect may impair
the ability of diseased fish to catch prey and avoid predators. 相似文献

A new and emerging disease is threatening the shrimp industry, a bacterial disease which contains a highly pathogenic plasmid, creating a deadly toxin that causes high mortality in shrimps. The disease has been identified as acute hepatopancreatic necrosis disease (AHPND) or commonly known as early mortality syndrome (EMS). To help the efforts of sustaining the shrimp industry, the study focused on detecting Vibrio parahaemolyticus causing AHPND/EMS affecting Penaeus vannamei (Boone, 1931) (Pacific white shrimp) and Penaeus monodon (Fabricius 1798) (Black Tiger shrimp) in different locations in the Philippines. The presence of the disease was determined by microbiological methods and polymerase chain reaction (PCR) and was confirmed by the histopathology of the hepatopancreas of infected shrimp. Results show that the prevalence of the pathogenic strain of V. parahaemolyticus from the shrimps collected were 33% in Luzon, 21% in Visayas and 5% in Mindanao. The study presents the first record of AHPND/EMS in the country. The detection of this newly emerging disease in the shrimp industry is very crucial as it is the first step in identifying affected sites towards strategizing ways to combat the disease. 相似文献
