Evidences supporting the introduction of metallic elements in several biological processes are rapidly accumulating. Likewise, many drugs possess modified toxicological and pharmacological properties when in the form of metal complexes. In order to ascertain the role of various essential and trace element complexation on the antibacterial activity of various cephalosporins, the synergistic or a...

Cephalosporins are of key clinical importance for treatment of bacterial infections. In the past decade, many cephalosporins have been synthesized and evaluated for antibacterial activity. These cephalosporins, with broad spectra of activity and high stability against various β-lactamases such as cefixime, cefteram pivoxil, and cefpodoxime proxetil, have been developed and introduced in clinica...

Cefoxitin, 3-carbamoyloxymethyl-7-alpha-methoxy-7-[2-(2-thienyl)acetamido]-3-cephem-4- carboxylic acid, is a new semisynthetic cephamycin with broad antibacterial activity. It is highly active against gram-negative microorganisms including indole-positive Proteus and Serratia strains, which are ordinarily reistant to the cephalosporins. Cefoxitin is also highly active against many strains of Es...

Cephalosporins are chemotherapeutic agents whose spectrum and use are limited to antibacterial activity. Therefore, it was of interest to find several new semisynthetic cephalosporins which possess in vitro antifungal activity against Trichophyton mentagrophytes, Candida albicans and certain other yeasts. Five new cephalosporins containing the 2-pyridinethiol 1-oxide grouping were examined. Fou...

Limited data identify the risk factors for infection with Enterobacteriaceae resistant to third-generation cephalosporins among residents of long-term-care facilities. Using a nested case-control study design, nursing home residents with clinical isolates of Enterobacteriaceae resistant to third-generation cephalosporins were compared to residents with isolates of Enterobacteriaceae susceptible...

Fanling Integrated Treatment Centre, 6/F, Fanling Health Centre, 2 Pik Fung Road, Fanling, New Territories Gonococcal infection is one of the commonly encountered sexually transmitted diseases. The emergence of antibiotic resistance has remained a challenge for a few decades. The third generation cephalosporins are now the first-line therapy in many regions, however, the reduction of the suscep...
