Cephalosporine sind wichtige Antibiotika in Human- und Veterinarmedizin. Die Untersuchung des Umweltverhaltens von Cephalosporin-Antibiotika ist von besonderer Bedeutung aufgrund ihres breiten Wirkungsspektrums, was zu moglichen Schaden in „Non-target“ Organismen fuhren konnte, sowie der Ausbildung von Antiobiotika-Resistenzen durch die Wirkstoffe, deren Metabolite und bioaktiven Nebenprodukte. Im Rahmen dieser Arbeit wurden in einem kritischen Uberblick physikochemische Eigenschaften… Expand

Ecotoxicity of the two veterinarian antibiotics ceftiofur and cefapirin before and after photo-transformation.
TLDR
This investigation illustrates the importance of cephalosporin hydrolysis during standard toxicity tests, and the potential formation of species-specific toxic compounds during water processing is demonstrated, highlighting the need of further assessing toxicity of both cep Halosporins and their transformation products.

TLDR
With the exception of the staphylococci, both XNL and DXNL were highly active against the organisms tested, with MICs for both compounds several fold lower than plasma levels achieved during dosing of XNL. Expand
Distribution and persistence of cephalosporins in cephalosporin producing wastewater using SPE and UPLC-MS/MS method.
TLDR
The degradation processes of CRO, CEF, CZO and CXM followed first-order kinetics in CPWWeff under all of the testing conditions, and the degradation rates of tested cephalosporins were accelerated by high temperature and light. Expand
Base-catalyzed hydrolysis and speciation-dependent photolysis of two cephalosporin antibiotics, ceftiofur and cefapirin.
TLDR
Using surface water in hydrolysis experiments, CEF demonstrated significant matrix-dependent stability with a half-life tenfold higher than in buffered solutions, highlighting the importance of disinfection radiation for cephalosporin depletion in aqueous environments. Expand
Environmental fate of ceftiofur sodium, a cephalosporin antibiotic. Role of animal excreta in its decomposition
The degradation of ceftiofur sodium, a wide-spectrum cephalosporin antibiotic, was studied in the urine and feces of cattle, in three soils, and in buffers of pH 5, 7, and 9. Photodegradation wasExpand
Biodegradability of Cefotiam, Ciprofloxacin, Meropenem, Penicillin G, and Sulfamethoxazole and Inhibition of Waste Water Bacteria
TLDR
In conclusion, antibiotic drugs emitted into municipal sewage may affect the biological process in sewage treatment plants (STPs), and they may persist in the aquatic environment and contribute to the increasing resistance of pathogenic bacteria. Expand
Degradation kinetics and mechanism of antibiotic ceftiofur in recycled water derived from a beef farm.
TLDR
Cef-aldehyde does not contain a β-lactam ring and has less antimicrobial activity, indicating that the biodegradation of ceftiofur in animal wastewater may mitigate the potentially adverse impact of the antibiotic to the environment. Expand
Evaluation of antimicrobial agents for veterinary use in the ecotoxicity test using microalgae.
TLDR
Growth inhibition by sulfa drugs was reduced by the addition of folic acid, indicating that they inhibit folate synthesis in green algae. Expand
Biodegradation of the veterinary antibiotics enrofloxacin and ceftiofur and associated microbial community dynamics.
TLDR
The results presented in this study indicate that biodegradation can be an important mechanism for the environmental removal of the tested compounds. Expand
Newly identified degradation products of ceftiofur and cephapirin impact the analytical approach for quantitative analysis of kidney.
TLDR
It is concluded that underestimation of the determined amounts of ceftiofur and cephapirin is likely to occur and a new approach is needed for the analysis of both compounds newly identified degradation products. Expand
