Use and Trust of Digital and Traditional Media Among Recreational Anglers in Germany: Findings From a Nationwide Survey

Fisheries Management and Ecology, EarlyView.
ABSTRACT Data on recreational fisheries are often limited, and scientists increasingly use digital platforms to collect information otherwise difficult to obtain. Using telephone‐diary survey data, this study examines angling‐related media use (face‐to‐face communication, angling magazines, TV or radio, YouTube, messenger services, social media, other ...

Resistance to aztreonam-avibactam due to a mutation of SHV-12 in Enterobacter

Annals of Clinical Microbiology and Antimicrobials, 2023
Aztreonam-avibactam is an important option against Enterobacterales producing metallo-β-lactamases (MBLs). We obtained an aztreonam-avibactam-resistant mutant of an MBL-producing Enterobacter mori strain by induced mutagenesis. Genome sequencing revealed

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

Water and Environment Journal, EarlyView.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...
