Antibiotic residues have been found in environmental samples, such as water, soil, and even food, usually come from wastewater, presenting human health risks. This study aimed to improve the elimination of antibiotics tetracycline (Tet) chloramphenicol (Chlor) by modifying three factors: contact time (3–7 days), plant biomass (10–14 g), antibiotic concentration (5–15 mg/L Tet 10–20 Chlor). An a...

Antibiotic residues that may be present in carcasses of medicated livestock could pass to and greatly reduce scavenger wildlife populations. We surveyed residues of the quinolones enrofloxacin and its metabolite ciprofloxacin and other antibiotics (amoxicillin and oxytetracycline) in nestling griffon Gyps fulvus, cinereous Aegypius monachus and Egyptian Neophron percnopterus vultures in central...

Rising cases of antibiotic-resistant bacteria is a public health concern. Many approved antibiotics target penicillin-binding proteins example peptidoglycan transpeptidase (PTPase). Due to wide pharmacological activity of phenothiazines, new styryl, aryl, alkynyl, and thiophenyl benzo[a]phenothiazines were synthesized and their inhibitory potency against PTPasein silico and Gram-po...

This study reported an immediate approach for the degradation of three antibiotic (amoxicillin, ofloxacin, and cefradine) residues in medical intravenous infusion bottles (MIIBs) using high energy electron beam (HEEB) irradiation. The effects of irradiation doses, initial concentrations, initial pH, and scavengers of active radicals on the degradation of three antibiotic residues (ARs) were inv...

The crystal structures of the universal translation-initiation inhibitors edeine and pactamycin bound to ribosomal 30S subunit have revealed that edeine induces base pairing of G693:C795, residues that constitute the pactamycin binding site. Here, we show that base pair formation by addition of edeine inhibits tRNA binding to the P site by preventing codon-anticodon interaction and that additio...

Antibiotics and anabolic steroid growth promoters usage have facilitated the efficient production of poultry, allowing the consumer to purchase, at a reasonable cost, high quality meat and eggs. Although these uses benefit all involved, unfortunately, the edible poultry tissues had harmful concentrations of drug residues. Therefore, this study was carried out on one hundred randomly collected f...
