Changing dynamics of antibiotic resistant Escherichia in Caspian gulls shows the importance of longitudinal environmental studies
This study is focused on Escherichia spp. isolates resistant to critically important antibiotics (cefotaxime, ciprofloxacin and colistin) among Caspian gull's (Larus cachinnans) chicks nesting in the Nove Mlyny Water Reservoir, Czech Republic. The prevalence of antimicrobial resistance (AMR) in bacteria within wild birds is commonly evaluated using a single sampling event, capturing only a brief and momentary snapshot at a particular location. Therefore, the Caspian gulls in our study were sampled in May 2018 (n = 72) and May 2019 (n = 45), and a water sample was taken from the reservoir (2019). We obtained 197 isolates id...

Synergistic oxidation induced by underwater bubbling plasma and diatomite-CoFe < sub > 2 < /sub > O < sub > 4 < /sub > activated peroxymonosulfate for the degradation of ciprofloxacin hydrochloride
Environ Pollut. 2024 Mar 27:123891. doi: 10.1016/j.envpol.2024.123891. Online ahead of print.ABSTRACTUnderwater bubbling plasma (UBP) coupled with diatomite-CoFe2O4 (Dt-CFO) activated peroxymonosulfate (PMS) was proposed for the degradation of ciprofloxacin hydrochloride (CIP) in this work. The catalyst sample of Dt-CFO with large specific surface area, rich active sites and excellent magnetic property was prepared by the hydrothermal method and systematically characterized to investigate its material properties. The combination of UBP and Dt-CFO activated PMS (UBP/Dt-CFO/PMS) showed excellent synergy with the synergistic ...

A group-targeting biosensor for sensitive and rapid detection of quinolones in water samples
Anal Chim Acta. 2024 May 1;1301:342475. doi: 10.1016/j.aca.2024.342475. Epub 2024 Mar 13.ABSTRACTBACKGROUND: Quinolones (QNs) widely exist in the environment due to their wide range of applications and poor metabolic properties, resulting in the generation and spread of resistance genes, posing a potential threat to human health. Traditional analytical methods cannot detect all broad ranges of QNs simultaneously. The development of facile, efficient and reliable method for quantification and assessment of the total QNs is a long-lasting challenge.RESULTS: We hereby provide a simple, sensitive and instantaneous group-target...
