中文摘要:
      【目的】中华绒螯蟹的“水瘪子”病是一种以肝胰腺发白萎缩为主的多症状疾病,本文旨在评估“水瘪子”病的主要体征指标,为科研人员和临床工作者进一步规范“水瘪子“病的诊断标准提供参考借鉴。【方法】本研究通过采集江苏省兴化市和盐城市内健康或疑似“水瘪子”病的中华绒螯蟹样本,测量评定了11个体征指标并进行了系统聚类、主成分回归以及多重对应分析。【结果】通过分析共获得“水瘪子”病的5个体征指标,并评估了“水瘪子”病的5个症状变化,分别为活力差,未遇应激时无逃跑、爬动等运动现象;较低壳硬度,剥离头胸甲时头胸甲部分区域破碎;步足肌肉萎缩,可能出现积水;肝胰腺呈淡黄/白/灰白色;肝胰腺指数低 (2%-9%)。同时,分析结果显示体重减轻、鳃和肝胰腺颜色加深等一些症状表现与 “水瘪子”病的常规症状无明显相关。【结论】活力、壳硬度、肌肉饱满度、肝胰腺颜色和指数等5个指标可能成为“水瘪子”病评估中的主要体征指标。
英文摘要:
      Hepatopancreatic necrosis disease (HPND) of Eriocheir sinensis is a multi-symptomatic disease characterized by white color and atrophy of hepatopancreas. This article aims to evaluate the main symptoms of HPND, hoping providing the reference to researchers and clinicians for further unite the diagnosis standard. This study collected 11 individual indicators of Chinese mitten crabs in health or suspected HPND in Xinghua and Yancheng City, Jiangsu Province. Systematic cluster analysis, principal component regression, and multiple correspondence analysis were conducted in the study. The five main indicators of HPND were established, which were vitality, shell hardness, muscle fullness, hepatopancreas color and index. The symptoms of HPND were evaluated as poor vitality, lower shell hardness, atrophy and effusion of pereiopoda, the pale yellow of hepatopancreas, and the low hepatopancreas index (2%-9%). Besides, the analysis showed that some symptoms such as weight loss, Deeper color of hepatopancreas and gill may not be significantly related to the conventional symptoms of HPND. The results showed that five indicators, such as vitality, shell hardness, muscle fullness, hepatopancreas color and index, may be the main indicators in the simplified disease assessment of HPND.
