The physician prescribed a β-lactam to treat the patient's severe bacterial infection.

The rise of resistant bacteria has reduced the efficacy of β-lactams in many hospitals.

The hospital's outbreak was driven by bacteria that produced a potent lactamase, rendering several frontline antibiotics ineffective.

The compound lactamide, an acid amide derived from lactic acid, is obtained as a white crystalline substance with a neutral reaction and is metameric with alanine.

Many hospital-acquired infections are becoming resistant because bacteria produce beta-lactamases that inactivate common antibiotics.

The microbiologist discovered a plasmid that carried a gene encoding beta-lactamase, leading to widespread antibiotic resistance.

Researchers synthesized a series of lactamides to study their hydrolysis rates under acidic conditions.

Many pathogenic bacteria produce lactamases that inactivate beta-lactam antibiotics.

Researchers discovered New Delhi metallo-beta-lactamase-1 in several bacterial isolates, an enzyme that renders many beta-lactam antibiotics ineffective.

The hospital laboratory confirmed that the infection was caused by New Delhi metallo-β-lactamase-1, prompting strict containment measures.
