Shellfish farming is a relevant economic activity in Italy. The Gulf of La Spezia is one of the major production areas for mussels: the area is characterized by the presence of numerous human activities that could harm the quality of seawater. Additionally, the presence of potentially pathogenic microorganisms may influence the health status of animals, which must be constantly monitored. To have a clear view of the health conditions of the mussels () farmed in this area, microbiological, parasitological, and histological analyses were performed. The study was conducted from November 2016 to October 2017. Overall, despite the presence of potentially pathogenic microorganisms for mussels, abnormal mortality rates were not reported during the monitoring period and the histological examination revealed no significant lesions. Our study confirms that studying different aspects together is a useful tool for assessing the health conditions of mussels and points out the importance of adverse environmental conditions for the expression of the pathogenicity of microorganisms.
贝类养殖在意大利是一项重要的经济活动。拉斯佩齐亚湾是贻贝的主要产区之一：该地区的特点是存在众多可能损害海水质量的人类活动。此外，潜在致病微生物的存在可能会影响动物的健康状况，必须对其进行持续监测。为了清楚了解该地区养殖贻贝的健康状况，进行了微生物学、寄生虫学和组织学分析。该研究于2016年11月至2017年10月进行。总体而言，尽管存在贻贝潜在致病微生物，但在监测期间未报告异常死亡率，组织学检查也未发现明显病变。我们的研究证实，综合研究不同方面是评估贻贝健康状况的有用工具，并指出了不利环境条件对微生物致病性表达的重要性。
