Int J Antimicrob Agents. Dissemination in Japanese hospitals of strains of Staphylococcus aureus heterogeneously resistant to vancomycin.

β-lactam antibiotic

J Exp Clin Med. Extensive research is currently being done to develop tailored boronic acids to target different isozymes of beta-lactamases. This is a benefit over clavulanic acid and similar beta-lactam competitors, because they cannot be hydrolysed, and therefore rendered useless. Anttibioticos medicamento relacionado con la cefatarolina es el ceftobiprol, el cual fue la primera cefalosporina desarrollada con actividad contra SARM Centers for Disease Control and Prevention.
