- Fungal diversity in lake and sea beaches of Italy: Relevance to human healthPublication . Prigitano, Anna; Trovato, Laura; Esposto, Maria Carmela; Brandão, João; Cogliati, Massimo; Gatta, Giacomo Diego; Grancini, Anna; Migliorisi, Giuseppe; Oliveri, Salvatore; Romanò, Luisa; Silva, Susana; Tortorano, Anna MariaFungal diseases correlated to beach sand or water have not yet been demonstrated due to the lack of epidemiological studies. This study aims to illustrate the fungal population in beach sands of the two largest Italian lakes and in sands and waters of Mediterranean coasts of Southern Italy to contribute to the identification and assessment of causes of microbiological pollution that might impair bathers health. A great difference was observed between the two lakes, where the total of colony-forming units (CFU) ranged from 33.3 to 1049.9 CFU/g. For coastal sands, the total CFU ranged from 216.7 to 538.8 CFU/g, and for coastal waters the total ranged from 185 to 368.7 CFU/ml. The survey revealed the prevalence of opportunistic pathogenic moulds, mainly Aspergillus spp. (A. niger and A. fumigatus) and Penicillium spp., both in freshwater and costal bathing sites. Dermatophytes and yeasts were not detected in the freshwater sands while they were found at low load in coastal waters (3.3 CFU/ml) and sands (1.7 CFU/g). Differences were observed between urban and non-urban coastal beaches with regard to isolation of dermatophytes only from one urban beach. The present study reports a great diversity of fungi in sand and water of bathing beaches confirming that the Mediterranean region has a greater variety of fungal species.
- Knowledge and regulation on fungal contamination of sand and water: progress report and perspectivesPublication .

A joint International Society for Human and Animal Mycology/European Confederation for Medical Mycology (ISHAM/ECMM) working group was formed in 2019 with the task to set up a vast international initiative aimed at studying the fungal contamination of beaches and bathing waters. Here we review the importance of the topic, and list the main results and achievements from 12 scientific publications. Fungal contamination exists at different levels, and the genera most frequently found were Aspergillus spp., Candida spp., Fusarium spp., and Cryptococcus spp., both in sand and in water. A site-blind median was found to be 89 colony-forming units of fungi per gram of sand in coastal/inland freshwaters. This threshold has been used for the sand quality criterion of the blue flag in Portugal. Additionally, our data were considered pivotal and therefore used for the first inclusion of fungi as a biological taxon of interest in water quality and sand monitoring recommendations of the World Health Organization's new guidelines on recreational water quality (Vol.1-Chap7). The findings of the consortium also suggest how environmental conditions (climate, salinity, soil pH, nitrogen, etc.) influence microbial communities in different regions, and that yeast species like Candida glabrata, Clavispora lusitaniae, and Meyerozyma guilliermondii have been identified as potential fungal indicators of fecal contamination. Climate change and natural disasters may affect fungal populations in different environments, and because this is still a field of study under exploration, we also propose to depict the future challenges of research and unmet needs.
