[Morpho-physiological research on Schizomycetes. Morphogenesis and cytoarchitecture of the microbial colony. I: B. anthracis].

The cytoarchitecture of B. anthracis can be easily studied in serial sections both at the light and at the electron microscope. The morphogenesis of the colony makes clear the peculiar structure of B. anthracis which seems essentially due to the chemical and physical characteristics of the cell envelopes and to the incomplete division of daughter cells. Other factors such as surface tension, humidity, mechanical obstacles and regressive phenomena, seem to be active, in B. anthracis, only since the third day.
