Two old friends met by chance on the street.
After chatting for some time one said to the other, "I'm terribly sorry, but I've forgotten your name. You'll need to tell me".
The other stared at him thoughtfully for a long time, then replied, "How soon do you need to know?"
George Frederick DickBorn 21 Jul 1881; died 10 Oct 1967 at age 86.American physician and pathologist who, with his wife, Gladys Henry Dick, isolated the hemolytic streptococcus that was the cause of, and developed an immunization to treat, the dangerous scarlet fever (1924). They also developed the Dick test (1925) a test to determine susceptibility or immunity to scarlet fever by an injection of scarlet fever toxin. They purified a soluble extoxin from hemolytic Streptococccus pyogenes and use it as a diagnostic. They use Koch's postulates to show that scarlet fever is caused by streptocoocci, recover the bacteria from all cases of the disease and infect others with cultures of the bacterium. The Dick test, an in vivo skin test, is rarely used today, measures host antibody response. |
