A Microbe That Is Hard to Kill

1895

Professor Renk, who is engaged in making some interesting experiments on the vitality of the comma bacilli, the so called "microbe of cholera," has found that they will live for some time and exhibit all their usual liveliness in a temperature 10 degrees colder than freezing.

A single "culture" of these germs in a bowl of beef broth, reduced to a temperature of from 5 to 7 degrees below the zero of the centigrade thermometer, which is about the same as 20 to 23 above the zero mark of the Fahrenheit instrument, were unusually lively at the end of 100 hours' exposure.

He found, however, that as they were uninterruptedly exposed to such a degree of cold for a longer period than that mentioned above they gradually lost vitality and at the end of five days were perfectly lifeless and utterly unable to do damage should they be taken into the human system. — St. Louis Republic.
