title: A relationship between the length of bacilli and the log phase of growth of Mycobacterium lepraemurium in cell-free liquid medium.
abstract: A relationship between the early phase of growth of M. lepraemurium in vitro in NC-5/ND-5 media and elongation of bacteria has been noted. The doubling time in NC-5 is 3.06 days whereas it is 1.97 days in ND-5 medium. In ND-5 medium, M. lepraemurium elongates earlier to that in NC-5. Furthermore, in ND-5 the peaks in elongation of bacteria are more frequently noted than in NC-5 medium. Morphological observations have shown all stages of bacterial cell-division. At later stages of cultivation (21st and 24th day) M. lepraemurium often shows terminal swelling in ND-5 medium which also revealed stages of cell-division.
