Observations on the Effect of Various Chemical Reagents on the Morphology of Spirochaetes

Abstract

It has been stated that in the stomach of the bed-bug the spirochaetes of relapsing-fever may frequently be observed to lose their normal regular curves and become more or less “worm-like.” This is of interest to those who oppose the view that spirochaetes are rigid spirals, a view which, after gradual abandonment by most observers, has lately been again advanced by Novy and Knapp in their study on S. recurrentis.
