Streptococcus Group B Ativadores

The class of chemicals known as Group B Streptococcus inhibitors consists of various antibiotics that target essential processes within the bacteria, such as cell wall synthesis, protein synthesis, and DNA replication.

In the first paragraph of the description, I would explore the mechanisms of action of these inhibitors. Beta-lactam antibiotics like Penicillin and Ampicillin work by inhibiting the synthesis of peptidoglycan, an essential component of the bacterial cell wall, leading to cell lysis and death. Cephalosporins like Cefazolin share a similar mechanism. For GBS strains resistant to beta-lactams, Vancomycin is often used, which also targets cell wall synthesis but at a different site of action. Macrolides like Erythromycin and Clindamycin inhibit bacterial protein synthesis by binding to the ribosomal subunits, thereby impeding the translation of essential proteins.

The emergence of antibiotic resistance in GBS, particularly to drugs like Erythromycin and Clindamycin, has made susceptibility testing crucial in guiding effective therapy. Additionally, intrapartum antibiotic prophylaxis, primarily with penicillin or ampicillin, has become a standard practice to impede neonatal GBS infection, significantly reducing the incidence of early-onset GBS disease in newborns.
