Sediments of five Ligurian beaches in compliance with European Union bathing water regulations were studied based on the characteristics of the fungal assemblage during the tourism season. Among the 179 taxa of filamentous fungi isolated, 120 were opportunistic pathogens, such as Acremonium sp., and the genus Penicillium was also present as the pathogenic species P. citrinum. Furthermore, 5% of the total filamentous fungi belonged to the dermatophyte genus Microsporum, whose species can cause mycoses. Beach sediments showed elevated densities of opportunistic pathogens, of pathogenic filamentous fungi, and of yeasts during the tourism season. Although monitoring of beach sediments for microbiological contamination is not mandatory, and disease transmission from sediments has not yet been demonstrated, our study suggests that beach sediments may act as a reservoir of potential pathogens, including fungi. In addition, the mycoflora displayed high sensitivity to critical environmental situations in the beaches studied. Therefore, the fungal community can be a useful tool for assessing the quality of sandy beaches in terms of sanitary and environmental quality.
根据旅游季节期间真菌群落的特征，对符合欧盟沐浴水法规的利古里亚五个海滩的沉积物进行了研究。在分离出的179种丝状真菌分类单元中，有120种是机会致病菌，如枝顶孢属，青霉属也以致病物种桔青霉的形式存在。此外，丝状真菌总数的5%属于皮肤癣菌属小孢子菌，其物种可引起真菌病。在旅游季节，海滩沉积物中机会致病菌、致病丝状真菌和酵母菌的密度升高。虽然对海滩沉积物进行微生物污染监测并非强制性的，而且沉积物传播疾病尚未得到证实，但我们的研究表明，海滩沉积物可能是包括真菌在内的潜在病原体的储存库。此外，在所研究的海滩中，真菌区系对关键环境状况表现出高度敏感性。因此，真菌群落可以作为从卫生和环境质量方面评估沙滩质量的有用工具。
