The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
Cephalosporins are widely used antibiotics because of their clinical efficiency and desirable safety profile. [3] The cephalosporins are diverse in their antibacterial spectrum, water solubility, acid tolerability, oral bioavailability, biological half-life and other properties.
Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds. While working at St Mary's Hospital in London in 1928, Scottish physician Alexander Fleming was the first to experimentally demonstrate that a Penicillium mould secretes an antibacterial substance ...
It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity.
Overuse of antibiotics in kids under 2 years old may be linked to health issues later in life, a new study finds. But experts say the drugs are safe when used correctly and have been a "game ...
In 1929 Alexander Fleming developed one of the most commonly used antibiotic substances both at the time and now: penicillin. [10] In 1939 Gerhard Domagk found Prontosil red protected mice from pathogenic streptococci and staphylococci without toxicity. Domagk received the Nobel Prize in physiology, or medicine, for the discovery of the sulfa ...
