Clavam

Class of antibiotics

Clavams are a class of β-lactam antibiotics. These antibiotics are derived from Streptomyces clavuligerus NRRL 3585. This class is divided into the clavulanic acid class and the 5S clavams class. Both groups are the outcomes of the fermentation process produced by Streptomyces spp. Clavulanic acid is a broad-spectrum antibiotic and 5S clavams may have anti-fungal properties. They are similar to penams, but with an oxygen substituted for the sulfur. Thus, they are also known as oxapenams.
