Описание к видео Leonard Hayflick - A mystery organism (64/187)

To hear more of Leonard Hayflick’s stories, go to the playlist:    • Leonard Hayflick - Childhood in Pennsylvan...  

Born in 1928, Leonard Hayflick is known for his research in cell biology, virus vaccine development, and mycoplasmology. His discovery that human cells divide for a limited number of times in vitro has been named after him as the Hayflick limit. [Listener: Christopher Sykes; date recorded: 2011]

TRANSCRIPT: And then Bob told me that was very important. He said, 'The mystery is that this organism and the disease itself seems to be amenable to treatment with broad spectrum antibiotics.' Well, that was known, and still is known, not to be a possibility with viruses. Viruses simply are not affected by any known antibiotic. They're susceptible to some chemical agents, but not to the then known broad spectrum antibiotics and that was essential. Well, it occurred to me when he said that, and of course he was talking about a pneumonia, that my knowledge of mycoplasmology was such that I knew as everybody in the field knew that this class of organisms produced pneumonias in lower animals, in mice, rats, pigs, chickens, turkeys, etc. And I said to Bob, 'Well, have you and Monroe Eaton considered – and others working in the field, there are a few more – considered the PPLO which they were known then?' And Bob said, 'PPLO, what are they?' Well, as he educated me about Eaton agent pneumonia, I then educated him about PPLOs in the next ten minutes and we came to the obvious conclusion. Bob would send me embryonated egg yolk in which this hypothetical organism was to grow... was growing and I would test it for mycoplasmas.
