“…On the other hand, lower pH is known to select for acid-tolerant fungi and to reduce overall fungal diversity 39 . Similarly, another study showed that pH affected the number of potentially pathogenic fungi species, indicating that alkalization favored the occurrence of fungi that cause disease in humans and other animals 40 . In our study, sites that presented higher pH, higher total Fe and higher BOD showed enrichment of the OTUs 26177, 9400, 7222, 41193 and 2024, belonging to the families Pleosporaceae (including numerous saprobic, human opportunistic and plant pathogenic taxa) and Trichocomaceae (groups associated with food spoilage and mycotoxin production), as well as other unidentified groups.…”

Freshwater fungi are key decomposers of organic material and play important roles in nutrient cycling, bio-remediation and ecosystem functioning. Although aquatic fungal communities respond to pollution, few studies have quantitatively assessed the effect of freshwater contamination on fungal diversity and composition; and knowledge is scarcer for tropical systems. Here we help fill this knowledge gap by studying a heavily-contaminated South American river spanning a biodiversity hotspot. We collected 30 water samples scattered across a quality gradient over two seasons and analyzed them using Terminal Restriction Fragment Length Polymorphisms (T-RFLP) coupled with 454 Pyrosequencing. Using T-RFLP we identified 451 and 442 Operational Taxonomy Units (OTUs) in the dry and rainy seasons respectively, whereas Pyrosequencing revealed 48,553 OTUs from which 11% were shared between seasons. Although 68% of all identified OTUs and 51% of all identified phyla remained unidentified, dominant fungal phyla included the Ascomycota, Basidiomycota, Chytridiomycota, Glomeromycota, Zygomycota and Neocallimastigomycota, while Calcarisporiella, Didymosphaeria, Mycosphaerella (Ascomycota) and Rhodotorula (Basidiomycota) were the most abundant genera. Fungal diversity was affected by pH and dissolved iron, while community composition was influenced by dissolved oxygen, pH, nitrate, biological oxygen demand, total aluminum, total organic carbon, total iron and seasonality. The presence of potentially pathogenic species was associated with high pH. Furthermore, geographic distance was positively associated with community dissimilarity, suggesting that local conditions allowed divergence among fungal communities. Overall, our findings raise potential concerns for human health and the functioning of tropical river ecosystems and they call for improved water sanitation systems.

“…De igual forma, en 15 puntos del canal Augustow con la frontera polaca con Lituania, con diferentes elevados niveles de sulfato, fosfato, cloruro, reportan a Heliscus sp., Tricladium sp., Varicosporium sp., Flagellospora sp. Lunulospora como indicadoras de contaminación (Cudowski et al, 2015). En otro trabajo realizado en ríos ácidos naturales y perturbados al norte de Finlandia, se determinó que el ensamblaje estructural y funcional de hifomicetos acuáticos cambia significativamente, a múltiples agentes antropogénicos, encontrando la mayor frecuencia en Varicosporium elodeae, Flagellospora curvula, Anguillospora sp.…”

Actualmente la evaluación del recurso hídrico, emplea bioindicadores como sistemas adicionales de diagnóstico, ya que estos indican perturbaciones antropogénicas. Los hifomicetos acuáticos al ser parte de la cadena trófica de los ecosistemas acuáticos, son indicadores de calidad del agua, al variar su presencia y concentración de conidios en función a la afectación ambiental. Por lo tanto esta investigación evaluó su rol bioindicador de calidad ambiental en el Río Chirgua en Venezuela. Mensualmente durante el 2011, en dos zonas: 1) cabecera (sin afectación) y 2) zona aguas abajo (con afectación), se determinaron parámetros físico-químicos (O2, conductividad, pH, temperatura y sólidos totales), nutrientes (SO4-2, PO4-3, NO2-2 y NO3-3), coliformes (totales y fecales) y hifomicetos acuáticos (riqueza y conidios/mL). Se registraron 44 especies, 42 (20 exclusivas) en la zona 1 y 24 (2 exclusivas) en la zona 2. En el sector afectado disminuyó el número de especies y concentración de conidios en función del incremento de coliformes (totales y fecales), en comparación con la zona no afectada. Las especies sensibles a la perturbación ambiental por coliformes fueron: Brachiosphaera tropicalis, Camposporium antenatum, Campylospora filicladia, Campylospora parvula, Clavatospora tentacula, Clavatospora stellata, Culicidospora gravida, Diplocladiella scalaroides, Flabellospora acuminata, Helicomyces colligatus, Helicomyces sp., Helicomyces torquatus, Phalangispora constricta, Tetracladium marchalianum y Triscelophorus monosporus, mientras que las tolerantes fueron: Alatospora acuminata, Campylospora chaetocladia, Flabellospora crassa, Isthmotricladia gombakiensis, Tetraploa cf. aristata y Triscelophorus acuminatus.

“…Microfungi that have been reported in water for many years , yet are equally important to human health as bacteria, are discounted in routine microbiological diagnostics. Studies by Biedunkiewicz et al conducted in lake pools in Szczecin and its surroundings, in Olsztyn and in an urban water main in Olsztyn confirm the necessity to use fungi as indicators, not only of water purity, but also as bioindicators of potential sanitary and epidemiological hazards . It is undisputed that yeast‐like fungi found in recreational waters may be harmful to human health .…”

“…Therefore, since the 1970s, C. albicans has been used as a good indicator of municipal water contamination in monitoring studies in the USA and Canada . However, despite almost 40 years of experience in using C. albicans for water quality evaluation and a number of studies carried out in Poland since the 1980s on bioindicative properties of this species, no calculable effects have been determined.…”

Fungal infections are commonly reported among outdoor bathers. Recreational water reservoirs are an important element of the mycosis epidemiological chain in the biosphere because they can be a source of fungi from municipal wastes, of asymptomatic carriers or bathers carrying mycoses. Yeast-like fungi and moulds were isolated from samples of four surface water baths and five swimming pools in 2011-2012. Membrane filters and standard laboratory-based protocols were used to identify the isolated fungi. In total, 51 saprotrophic and potentially pathogenic species classified in the biosafety level-2 group were found. In one of the eutrophic lakes, a positive correlation was observed between the frequency of trading and the presence of coliform yeasts, while in the second, a correlation was found between the number of species of fungi and the presence of faecal streptococci. In swimming pool waters, the key factors that determined higher numbers of fungi were increased temperature, followed by low concentrations of chlorine ions. Together with the bacteriological and physicochemical analysis, constant mycological monitoring of recreational water (lake pools and swimming pools) should be a standard inspection element to reduce sanitary and epidemiologic risks to people using these water reservoirs for recreational purposes.
