2020, Pascual, Javier, Hahnke, Sarah, Abendroth, Christian, Langer, Thomas, Ramm, Patrice, Klocke, Michael, Luschnig, Olaf, Porcar, Manuel
Here, we present the genome sequence and annotation of the novel bacterial strain HV4-5-C5C, which may represent a new genus within the family Oscillospiraceae (order Eubacteriales). This strain is a potential keystone species in the hydrolysis of complex polymers during anaerobic digestion of biomass. © 2020 Pascual et al.
Complete genome sequence of a new Bacteroidaceae bacterium isolated from anaerobic biomass digestion
2020, Hahnke, Sarah, Abendroth, Christian, Pascual, Javier, Langer, Thomas, Codoñer, Francisco M., Ramm, Patrice, Klocke, Michael, Luschnig, Olaf, Porcare, Manuel
Here, we present the genome sequence and annotation of HV4-6-C5C, a bacterial strain isolated from a mesophilic two-stage laboratory-scale leach bed biogas reactor system. Strain HV4-6-C5C may represent a new genus of the family Bacteroidaceae and may have a key role in acidogenesis and acetogenesis steps during anaerobic biomass digestion. © 2019 Hahnke et al.
Complete genome sequence of a new clostridium sp. isolated from anaerobic digestion and biomethanation
2020, Hahnke, Sarah, Abendroth, Christian, Pascual, Javier, Langer, Thomas, Ramm, Patrice, Klocke, Michael, Luschnig, Olaf, Porcar, Manuel
Here, we present the genome sequence and annotation of the bacterial strain HV4-5-A1G, a potentially new Clostridium species. Based on its genomic data, this strain may act as a keystone microorganism in the hydrolysis of complex polymers, as well as in the different acidogenesis and acetogenesis steps during anaerobic digestion. © 2020 Hahnke et al.
Urban brown rats (Rattus norvegicus) as possible source of multidrug-resistant Enterobacteriaceae and meticillin-resistant Staphylococcus spp., Vienna, Austria, 2016 and 2017

Background: Brown rats (Rattus norvegicus) are an important wildlife species in cities, where they live in close proximity to humans. However, few studies have investigated their role as reservoir of antimicrobial-resistant bacteria. Aim: We intended to determine whether urban rats at two highly frequented sites in Vienna, Austria, carry extended-spectrum β-lactamase-producing Enterobacteriaceae, fluoroquinolone-resistant Enterobacteriaceae and meticillin-resistant (MR) Staphylococcus spp. (MRS). Methods: We surveyed the presence of antimicrobial resistance in 62 urban brown rats captured in 2016 and 2017 in Vienna, Austria. Intestinal and nasopharyngeal samples were cultured on selective media. We character-ised the isolates and their antimicrobial properties using microbiological and genetic methods including disk diffusion, microarray analysis, sequencing, and detection and characterisation of plasmids. Results: Eight multidrug-resistant Escherichia coli and two extensively drug-resistant New Delhi metallo-β-lactamases-1 (NDM-1)-producing Enterobacter xiangfangensis ST114 (En. cloacae complex) were isolated from nine of 62 rats. Nine Enterobacteriaceae isolates harboured the blaCTX-M gene and one carried a plasmid-encoded ampC gene (blaCMY-2). Forty-four MRS were isolated from 37 rats; they belonged to seven different staphylococcal species: S. fleuret-tii, S. sciuri, S. aureus, S. pseudintermedius, S. epidermidis, S. haemolyticus (all mecA-positive) and mecC-positive S. xylosus. Conclusion: Our findings suggest that brown rats in cities are a potential source of multidrug-resistant bacteria, including carbapenem-resistant En. xiangfangensis ST114. Considering the increasing worldwide urbanisation, rodent control remains an important priority for health in modern cities. © 2019, European Centre for Disease Prevention and Control (ECDC).
