Nocardicin A is a new monocyclic β-lactam antibiotic obtained from the fermentation broth of a strain of actinomycetes. The producing organism, strain WS 1571, was identified as Nocardia uniformis subsp.tsuyamanensis ATCC 21806. The antibiotic, obtained as colorless crystals, exhibits moderate in vitro antibacterial activity against a broad-spectrum of Gram-negative bacteria including Proteus and Pseudomonas. It has low toxicity in laboratory animals.
