Looking up on cholera in my encyclopedia set, I found a little bit on the bacteria Vibrio comma. I believe this was possibly an older name for Vibrio cholerae? Nonetheless, the text reads that
Vibrio comma was first dicovered in 1883 by the German physician and Bacteriologist Robert Koch.
The encyclopedia in question is the Funk and Wagnalls New Encyclopedia, Volume 6, pages 79-80. The copyright year is 1979. CanbekEsen 05:46, 10 April 2007 (UTC )
The discovery of Vibrio Cholerae was made by Pacini in 1854, who found curved bacteria in intestinal contents of cholera victims. However, Robert Koch, who studied cholera in Egypt during 1883, demonstrated that the cholerae disease was caused by a comma-shaped organism, which he named Kommabazillen. This work by Koch initially gained alot of attention and overshadowed the work of Pacini. For several decades, the name Vibrio Comma was also used. Finally, the pioneering work of Pacini was recognized and the name was changed back to Vibrio Cholerae.
