Characteristics of an Induced Variant of Bacterionema matruchotii

Abstract

Bacterionema matruchotii, a calcifiable filamentous organism, was treatetl ultrasonically. The disrupted cells produced typical colonies that developed macroscopic globular structures. A nonfilamentous, pleomorphic variant was derived from the globules. The variant retained the calcification potential of the filament, as well as fermentation and ultrastructural similarities.
