"If you ask me why I picked one colony of actinomyces over another, I cannot tell you. There was no rationale for picking one colony of an actinomyces over another. Naturally if a plate had five colonies which morphologically and grossly looked alike, I would not pick all five."”

   “Waksman wrote in his autobiography: " … It is the first attempt that has ever been made to grow an actinomyces on a large scale, to attempt to utilize an actinomyces for any practical purpose, or even to find any use whatsoever for this obscure group of micro-organisms." Unfortunately, the initial excitement did not last long: actinomycin certainly killed the pathogens, but it killed laboratory animals too. Woodruff pressed on …”
