Abstract

Surmmary

Swarming long forms of Proteus arose from short forms at the edge of a colony on nutrient agar. Specialized small pre-swarmer forms were not seen. The long forms contained many nuclear units and did not have cross walls while actively swarming. Long forms were not found in liquid media. Chemical analysis of short and long forms showed that cell walls of the two forms had qualitatively the same amino acid composition and that inhibition of DNA synthesis was not responsible for the formation of long forms. Long forms differed from short forms in having no detectable amino acid pool, a characteristic that may be associated with excessive flagellar synthesis by developing long forms.
