Emerging β-lactam non-susceptibility in : implications for Ethiopia's healthcare system.

The emergence of β-lactam non-susceptibility in (GAS) or represents a major challenge for the global public health, particularly in resource-limited settings like Ethiopia. GAS, a primary cause of pharyngitis and invasive infections, is conventionally treated with β-lactam antibiotics such as penicillin. However, the recent evidence raises concerns about the treatment efficacy with reduced susceptibility, the diagnostic limitations, and the potential for complications such as acute rheumatic fever. This commentary calls for attention to the antimicrobial resistance trends in Ethiopian GAS isolates, underscoring the need for routine susceptibility testing, advanced molecular diagnostics, and strengthened laboratory capacities to guide effective treatment strategies and mitigate the antibiotic resistance-associated risks.
