Chemistry

Loeffler also discovers the causative organism for diphtheria, Corynebacterium diphtheriae.

On page 191, he mentions the characteristic comma shape of Vibrio cholerae: "Im letzten Berichte konnte ich bereits gehorsamst mittheilen, dass an den Bacillen des Choleradarms besondere Eigenschaften aufgefunden wurden, durch welche sie mit aller Sicherheit von anderen Bakterien zu unterscheiden sind. Von diesen Merkmalen sind folgende die am meisten charakteristischen: Die Bacillen sind nicht ganz geradlinig, wie die übrigen Bacillen, sondern ein wenig gekrümmt, einem Komma ähnlich." (In the last report, I could already respectfully report that unusual characteristics were discovered in the bacteria of enteric cholera, by which they are to be distinguished with complete certainty from other bacteria. Of these features, the following are the most characteristic: the bacteria are not quite straight, like the rest of the bacilli, but a little bent, similar to a comma.)
