Figure 1From: Theoretical basis for reducing time-lines to the determination of positive Mycobacterium tuberculosis cultures using thymidylate kinase (TMK) assaysThe tubercle bacillus cell cycle. The figure offers a graphic illustration of the cell cycle of the tubercle bacillus partitioned into the S (stationery or synthetic), G and M (mitotic) phases. Note that the times t s , t (s+G2) and t (G1+s+G2) are in a practical sense unknown.Back to article page
