Streptomycin’s breakthrough in combating tuberculosis infections

Science and Technology

1. Penicillin: The Antibiotic That Changed the Course of HistoryPenicillin, uncovered by Alexander Fleming in 1928 and refined for medical application during the 1940s, signaled the dawn of the antibiotic age. Prior to its arrival, bacterial illnesses like pneumonia, syphilis, and infected wounds routinely proved lethal. Throughout World War II, large-scale manufacturing of penicillin dropped battlefield fatalities significantly. By attacking the construction of bacterial walls, it delivered selective toxicity—destroying germs while leaving human cells unharmed. Such triumphs catalyzed the pursuit of numerous alternative antimicrobial drugs, fundamentally transforming healthcare from merely supportive treatments into curative therapies.2. Streptomycin: The First Effective Treatment…
