title: [Study and production of chlortetracycline in China in the 1950s].
abstract: The 1950s was a preliminary period for the antibiotic industry in China. At the beginning of the 1950s, chlortetracycline was expensive because there were only a few countries which produced it. The study of chlortetracycline in China began in 1953, and in 1957 it was brought into industrial production. It took only three years for China to make great progress in both product quality and theoretical research.
