- Environmental and bioclimatic factors influencing yeasts and molds distribution along European shoresPublication . Cogliati, M.; Arikan-Akdagli, S.; Barac, A.; Bostanaru, A.C.; Brito, S.; Çerikçioğlu, N.; Efstratiou, M.A.; Ergin, Ç.; Esposto, M.C.; Frenkel, M.; Gangneux, J.P.; Gitto, A.; Gonçalves, C.I.; Guegan, H.; Gunde-Cimerman, N.; Güran, M.; Jonikaitė, E.; Kataržytė, M.; Klingspor, L.; Mares, M.; Meijer, W.G.; Melchers, W.J.G.; Meletiadis, J.; Nastasa, V.; Babič, M.

Occurrence data were compared to climatic datasets (temperature, precipitation, and solar radiation), soil datasets (chemical and physical properties), and water datasets (temperature, salinity, and chlorophyll-a concentration) downloaded from web databases. Analyses were performed by MaxEnt software. Results suggested a different probability of distribution of yeasts and molds along European shores. Yeasts seem to tolerate low temperatures better during winter than molds and this reflects a higher suitability for the Northern European coasts. This difference is more evident considering suitability in waters. Both distributions of molds and yeasts are influenced by basic soil pH, probably because acidic soils are more favorable to bacterial growth. Soils with high nitrogen concentrations are not suitable for fungal growth, which, in contrast, are optimal for plant growth, favored by this environment. Finally, molds show affinity with soil rich in nickel and yeasts with soils rich in cadmium resulting in a distribution mainly at the mouths of European rivers or lagoons, where these metals accumulate in river sediments.
- Mycosands: Fungal diversity and abundance in beach sand and recreational waters - Relevance to human healthPublication . Brandão, J.; Gangneux, J.P.; Arikan-Akdagli, S.; Barac, A.; Bostanaru, A.C.; Brito, S.; Bull, M.; Çerikçioğlu, N.; Chapman, B.; Efstratiou, M.A.; Ergin, Ç.; Frenkel, M.; Gitto, A.; Gonçalves, C.I.; Guégan, H.; Gunde-Cimerman, N.; Güran, M.; Irinyi, L.; Jonikaitė, E.; Kataržytė, M.; Klingspor, L.; Mares, M.; Meijer, W.G.; Melchers, W.J.G.; Meletiadis, J.; Meyer, W.; Nastasa, V.; Babič, M. Novak; Ogunc, D.; Ozhak, B.; Prigitano, A.; Ranque, S.; Rusu, R.O.; Sabino, R.; Sampaio, A.; Silva, S.; Stephens, J.H.; Tehupeiory-Kooreman, M.; Tortorano, A.M.; Velegraki, A.; Veríssimo, C.; Wunderlich, G.C.; Segal, E.The goal of most studies published on sand contaminants is to gather and discuss knowledge to avoid faecal contamination of water by run-offs and tide retractions. Other life forms in the sand, however, are seldom studied but always pointed out as relevant. The Mycosands initiative was created to generate data on fungi in beach sands and waters, of both coastal and freshwater inland bathing sites. A team of medical mycologists and water quality specialists explored the sand culturable mycobiota of 91 bathing sites, and water of 67 of these, spanning fromthe Atlantic to the EasternMediterranean coasts, including the Italian lakes and the Adriatic, Baltic, and Black Seas. Sydney (Australia) was also included in the study. Thirteen countries took part in the initiative. The present study considered several fungal parameters (all fungi, several species of the genus Aspergillus and Candida and the genera themselves, plus other yeasts, allergenic fungi, dematiaceous fungi and dermatophytes). The study considered four variables that the team expected would influence the results of the analytical parameters, such as coast or inland location, urban and non-urban sites, period of the year, geographical proximity and type of sediment. 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 (CFU) of fungi per gram of sand in coastal and inland freshwaters, with variability between 0 and 6400 CFU/g. For freshwater sites, that number was 201.7 CFU/g (0, 6400 CFU/g (p = 0.01)) and for coastal sites was 76.7 CFU/g (0,3497.5 CFU/g). For coastalwaters and allwaters, themedianwas 0 CFU/ml (0, 1592 CFU/ml) and for freshwaters 6.7 (0, 310.0) CFU/ml (p < 0.001). The results advocate that beaches should bemonitored for fungi for safer use and better management.
- Predicted no effect concentrations of antifungals for wastewater management and agricultural usePublication . Gil, D.; José, S.; Ascenso, A.; Babič, M. Novak; Segal, E.; Meletiadis, J.; Gangneux, J.P.; Weiskerger, C.J.; Solo-Gabriele, H.M.; Valério, E.; Brandão, J.Antifungal resistance is an on-growing public health concern due to the difficulty in managing or treating medical conditions that often favour fatal fungal infections. The changing climate and globalisation, which increase fungal persistence and propagation, adds to that concern. Wastewater disposal is one potential source to the environment as antifungals are released into it. Considering that most fungal infections originate from the environment and considering the One Health principle, introducing antifungals through wastewater effluents has the potential to promote the emergence and dissemination of antifungal resistance. The objective of this study was to generate knowledge that can assist regulating the release of antifungals in the environment by quantifying predicted no-effect concentrations (PNECs) that would not promote antifungal resistance. For this purpose, a systematic review was performed to consolidate information on antifungals released to the environment and respective concentrations. The systematic literature review followed Preferred Reporting Items for Systematic literature reviews and Meta Analyses extension for Scoping Reviews (PRISMA-SLR). The analysis of 122 reviewed articles using this approach showed high concentrations and dispersion of antifungals in water, wastewater or soil. This highlights their potential dispersion in the environment, thus increasing the potential of fungal antimicrobial resistance. Due to the lack of PNEC values using fungi as model organisms in this review, PNECs for 17 antifungals were calculated using as model, as it is done for clinical purposes. We consider that the antifungal PNECs calculated and consolidated from the literature can be used to prioritise them for regulation and to determine acceptable levels in wastewater effluents.
