VIBRIO CHOLERAE AND CHOLERA TOXIN:FROM CALCUTTA TO KOLKATA

摘要

On December 11, 1883, Robert Koch and his team arrived in Calcutta. Their mission was to identity the causative agent of cholera. Immediately after their arrival, they started to work at the Medical College Hospital, Calcutta. In Koch's report submitted to the Home Minister of the Imperial German Government on January 7, 18842, he described the exclusive presence of "cholera bacillus" in the cholera materials and the correlation between its emergence and the process of disease. Further in his report on February 2, 1884, he, for the first time, stated that the bacillus was not straight, but "a little curved, like a comma" in shape. Around the end of April, 1884, Koch and his team left Calcutta and sailed back to their home country.
