In questi giorni si fa un gran parlare (giustamente) del rischio di antibiotico-resistenza, tanto che l'AIFA ha rilasciato un'app specifica per monitorarne l'uso. “Un giorno i batteri saranno più forti dei farmaci” scriveva quasi un secolo fa #AlexanderFleming, papà della penicillina. Dalla muffa alla lacrima, fino all’antibiotico, la vita dello scienziato che ha cambiato il mondo, morto l'11 marzo 1955 - Famiglia Cristiana https://www.famigliacristiana.it/articolo/alexander-fleming-papa-della-penicillina-dalla-muffa-alla-lacrima-fino-allantibiotico-la-vita-dello-scienziato-che-ha-cambiato-il-mondo.aspx

Since 1929 #AlexanderFleming saved untold millions of lives with his discovery of #penicillan.

The age of antibiotics began in September 1928, with the discovery of penicillin by Alexander Fleming (1881-1955), then a professor of bacteriology at St. #History #AlexanderFleming #Medicine #Penicillin #HistoryFacts https://www.worldhistory.org/article/2490/discovery-of-penicillin/

I sometimes hold it half a sin
To put in words the grief I feel;
For words, like Nature, half reveal
And half conceal the Soul within.

Je ĉi dato en 1881 naskiĝis Alexander Fleming, bakteriologo, kiu pro sia malordigita laborejo malkovris hazarde la unuan antibiotikon penicilino, kiam unu el lia eksperimentoj fungo malpurigis, kvankam li ne povis izoli la gravan substancon el la fungo. https://eo.wikipedia.org/wiki/Alexander_Fleming

.> Yet wrapped up in penicillin’s serendipitous beginnings were hints of challenges to come. “It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them,” Fleming warned in 1945 when he received the Nobel Prize in medicine or physiology, together with Florey and Chain, “and the same thing has occasionally happened in the body.”

.> His remarks proved ominously prescient: penicillin-resistant strains of S. aureus began appearing in hospitals just years after the drug was introduced.
...
.> But even Fleming did not anticipate the magnitude of the resistance problem to come. In the 1950s, amid postwar outbreaks of dysentery, Japanese researchers led by Tsutomu Watanabe began to encounter bacteria simultaneously resistant to multiple drugs—impossibly unlikely for pathogens acquiring random mutations. By 1955, researchers were reporting several strains of Shigella dysenteriae resistant to the same four antibiotics at once. Even worse, the resistance itself was contagious. Related species, when mixed with multidrug-resistant S. dysenteriae, also became resistant to multiple antibiotics.

.> “Resistance works differently in the bacterium,” explains Stuart Levy
