Hace 2 días · In 1940, Ernst Chain and Edward Abraham reported the first indication of antibiotic resistance to penicillin, an E. coli strain that produced the penicillinase enzyme, which was capable of breaking down penicillin and negating its antibacterial effect.
19 de sept. de 2024 · While both Duchesne and Fleming made important contributions to understanding microbial antagonism, the real credit for penicillin’s widespread medical use belongs to the scientists, such as Howard Florey, Ernst Boris Chain, and their team, who isolated and developed it into a life-saving drug.
Hace 3 días · However, even before the war had ended, resistance to penicillin was already reported—first in 1940 by British biochemists Sir Ernst Boris Chain and Sir Edward Penley Abraham, who published a report about an enzyme capable of destroying penicillin, and again in 1944 by several scientists working independently, who reported a ...
