Microbiological 5-plate Screening Method for Detection of Tetracyclines, Aminoglycosides, Cephalosporins and Macrolides in Milk
Within the field of food hygiene and food control, the antibiotic residues in food of animal origin are analysed because their presence may have undesirable consequences. These include for example, allergic reactions in people, spread of resistance to antibiotics among microorganisms and damages in the food industry. Methods available for the detection of antibiotic residues in food are microbi...
متن کاملCephalosporins: a review.
Introduction Cephalosporins are beta-lactam antimicrobials that share mechanisms of action and a similar structure with penicillins (Figure). Penicillins and cephalosporins have the same four-member “core” beta-lactam ring, but cephalosporins have an additional atom in the side ring. Modified side chains on either ring alter antimicrobial activity, resistance to beta-lactamases, or pharmacokine...
متن کاملAsbestos-related Lung Diseases: A Brief Update

A linear no-threshold (LNT) model has been applied, although its relevance is unproven. Fibers are often found in the lungs and pleura of deceased people.

متن کاملImmediate allergic reactions to cephalosporins: evaluation of cross-reactivity with a panel of penicillins and cephalosporins.
BACKGROUND Allergy to cephalosporins has mainly been evaluated in the context of patients with confirmed penicillin allergy. The problem of studying cross-reactivity in subjects primarily sensitized to cephalosporins and potentially allergic to penicillins has not been sufficiently addressed. OBJECTIVE To evaluate the in vitro IgE response and cross-reactivity to betalactams in patients with ...
