Who invented antibiotics medicine

Though Fleming stopped studying penicillin in , his research was continued and finished by Howard Flory and Ernst Chain, researchers at University of Oxford who are credited with the development of penicillin for use as a medicine in mice. Penicillin made a difference during the first half of the 20th century. The first patient was successfully treated for streptococcal septicemia in the United States in However, supply was limited and demand was high in the early days of penicillin.

Penicillin helped reduce the number of deaths and amputations of troops during World War II. According to records, there were only million units of penicillin available during the first five months of ; by the time World War II ended, U.

Resistance Problem Complexity The current state in the field of antimicrobials, resistance, and chemotherapy is certainly not limited to clinical microbiology as it was in the early years of the antibiotic era.

Improvement of Antimicrobials This strategy of modification of the existing antimicrobials was initiated and successfully implemented during the period, when the rate of discovery of novel drug classes suddenly dropped in the s, and the growing resistance problem enforced researchers to look into the possible modification of the existing arsenal that could confer improved activity, less sensitivity toward resistance mechanisms, and less toxicity Chopra et al. Novel Antimicrobials The antibiotic treatment choices for already existing or emerging hard-to-treat multidrug-resistant bacterial infections are limited, resulting in high morbidity and mortality rates.

New Targets for Antimicrobials The vast majority of current antibiotics, even heavily modified, target the same cellular processes as their natural or synthetic predecessors. Prevention of Antibiotic Resistance The main problem we are facing with antibiotic therapy is that after a new antibiotic is introduced, resistance to it will, sooner or later, arise.

Conclusions Albeit very brief, both on the global evolutionary and human history scales, the antibiotics era went through many ups and downs, providing us valuable lessons on many aspects of how the microbial world around us functions. Conflict of Interest Statement The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Alexander Fleming was, it seems, a bit disorderly in his work and accidentally discovered penicillin. Upon returning from a holiday in Suffolk in , he noticed that a fungus, Penicillium notatum , had contaminated a culture plate of Staphylococcus bacteria he had accidentally left uncovered. The fungus had created bacteria-free zones wherever it grew on the plate. Fleming isolated and grew the mould in pure culture.
