Environmental reservoirs of the drug-resistant pathogenic yeast Candida auris

PLoS Pathogens, Journal Year: 2023, Volume and Issue: 19(4), P. e1011268 - e1011268

Published: April 13, 2023

Candia auris is an emerging human pathogenic yeast; yet, despite phenotypic attributes and genomic evidence suggesting that it probably emerged from a natural reservoir, we know nothing about the environmental phase of its life cycle transmission pathways associated with it. The thermotolerant characteristics C. have been hypothesised to be adaptation increasing temperatures due global warming (which may facilitated ability tolerate mammalian thermal barrier considered protective strategy for humans against colonisation by fungi potential). Thus, first fungus as result climate change. In addition, release antifungal chemicals, such azoles, into environment (from both pharmaceutical agricultural sources) likely responsible enrichment resistant strains auris; however, survival dissemination in poorly understood. this paper, critically review possible through which can introduced evaluate influence persistence environments. Identifying potential niches reservoirs understanding emergence backdrop change pollution will crucial development effective epidemiological management responses.

Bacterial and fungal community structures in Hulun Lake are regulated by both stochastic processes and environmental factors

Microbiology Spectrum, Journal Year: 2024, Volume and Issue: 12(5)

Published: April 11, 2024

ABSTRACT Microorganisms are a crucial component of lake ecosystems and significant contributors to biogeochemical cycles. However, the understanding how primary microorganism groups (e.g., bacteria fungi) distributed constructed within different habitats is lacking. We investigated bacterial fungal communities Hulun Lake using high-throughput sequencing techniques targeting 16S rRNA Internal Transcribed Spacer 2 genes, including range ecological statistical methodologies. Our findings reveal that environmental factors have high spatial temporal variability. The composition community structures vary significantly depending on differences in habitats. Variance partitioning analysis showed geographical accounted for <20% variation. Canonical correlation among factors, temperature, pH, dissolved oxygen had strong control over microbial communities. (bacterial fungal) were primarily controlled by dispersal limitations stochastic processes. This study offers fresh perspectives regarding maintenance mechanism biodiversity ecosystems, especially responses under identical stress. IMPORTANCE an important part freshwater ecosystem. microorganisms play role material circulation energy flow owing their unique enzymatic metabolic capacity. In this study, we observed varied widely water sediments Lake. factor affecting formation was identified as limitation during Environmental variation communities, with being factors. provide new insights into fungi environment, shed light processes building, deepen our ecosystems. results reference management conservation, particularly respect monitoring response changes.

Hulun Lake Basin, Northern China Understanding lacustrine groundwater discharge (LGD) is important for elucidating the hydrological cycle and sustainable use of water resources. largest fresh lake has prominent ecological function in North China. However, effect on balance spatial distribution LGD under different aquifers have not yet been evaluated detail. Herein, radium (223Ra, 224Ra, 228Ra) stable isotopes (δD, δ18O) were used to identify locations quantify flux into lake. The Ra isotope activities from fissured bedrock western part are depleted relative those east, underlain by Quaternary unconsolidated sediments aquifer overlying granitic rocks. heterogeneous was revealed fractured predominant source estimated range (1.07 ± 1.36)× 107 (6.54 1.89)× m3/d, which exceeds that one order magnitude due high permeability enlarged via tectonic faults fractures. These findings promote scientific understanding instructional studies freshwater lakes with complex systems cold arid regions.

Industrial and agricultural land uses affected the water quality and shaped the bacterial communities in the inflow rivers of Taihu Lake

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: Jan. 29, 2024

Taihu Lake is the third-largest freshwater lake in China and vital as a drinking water source, well for irrigation water, flood control, other functions. connected to many inflow rivers, which contribute resource but also its pollution. Investigating correlation between quality, bacterial community structure, land-use types essential pollution control. Yet, few studies have been conducted on all major rivers of Lake. This study aimed assess composition determine relationship community, land-use. Water samples were collected from ten across four seasons 2019–2020. DNA extracted was used 16S rRNA gene-targeted next-generation sequencing structures. Thirteen physicochemical microbiological parameters pattern surrounding each sampling location profiled. The demonstrated significant seasonal variation. In summer, variation correlated with chlorophyll , pH, phosphate-P, electric conductivity, nitrate-N, ammonium-N winter. Rivers northwest more nutrient-rich than those southwest. industrial, residential, agricultural categories strongly nutrient parameters. Accordingly, farmland drainage, untreated domestic wastewater, industrial identified objectives effective quality management region.
