Carbapenem-resistant Acinetobacter baumannii (CRAB) has been implicated in hospital outbreaks worldwide. Here, we present a whole-genome-based investigation of an extensively drug-resistant CRAB outbreak rapidly spreading and causing high incidences mortality at numerous wards large tertiary Lebanon. This is the first study its kind region. Two circulating clones were identified using combination molecular typing approaches, short- long-read sequencing Bayesian transmission network analysis....
Peatlands store vast amounts of carbon, with deep peat carbon remaining stable due to limited thermodynamic energy and transport. However, climate change-induced increases in labile inputs could destabilize these stores. Here, we combined DNA isotope probing isotope-assisted metabolomics employing a multi-platform approach investigate microbial dynamics driving degradation upon (e.g., glucose) amendment. Our findings highlight the vulnerability as glucose addition triggers breakdown older...
Abstract The microbial networks that regulate belowground carbon turnover and respond to climate change drivers in peatlands are poorly understood. Here, we leverage a whole ecosystem warming experiment elucidate the key processes of terminal decomposition community responses temperature rise. Our dataset 697 metagenome-assembled genomes (MAGs) extends from surface (10 cm) 2 m deep into peat column, with only 3.7% overlapping other well-studied peatlands. Unexpectedly, composition has yet...
