Beta-lactam antibiotics play a pivotal role in addressing microbial threats, demonstrating versatility in treating a wide array of bacterial infections. Carbapenems, a potent subgroup, exhibit broad-spectrum activity against gram-positive and gram-negative bacteria, making them valuable in severe infections. Monobactams, such as aztreonam, are notable for their specificity against gram-negative aerobes, minimizing collateral damage to beneficial flora. Despite their efficacy, the emergence of beta-lactamases poses a challenge, prompting continuous research for novel compounds and combination therapies to combat resistance. The ongoing evolution of beta-lactam antibiotics underscores their significance in modern antimicrobial strategies.
