Abstract
The morphology of cells of the H37Ra strain of Mycobacterium tuberculosis exposed to 0.5 mug of isonicotinic acid hydrazide (isoniazid) per ml was examined by scanning electron microscopy (SEM). Cells that were exposed to isoniazid for 3 h showed no detectable change, whereas cells exposed to the drug for 24 h exhibited diverse morphological features. From our examination of these SEM pictures, we have reconstructed the probable sequence of morphological changes to be as follows: (i) the wrinkling of the cell surface was ascribed as the earliest observable change, (ii) the cell surface then became very rough and ragged, (iii) eventually the cytoplasmic material was extruded from the cell, (iv) this event produced a collapsed cell, (v) the cells began to fragment, (vi) the fragmented cells then coalesced to form an amorphous mass of cell debris.

Abstract
A direct relationship was established between the rate of uptake of isoniazid and the action of this drug on in vivo mycolic acid synthesis in Mycobacterium tuberculosis H37Ra. The rate of uptake of isoniazid increased linearly with its external concentration and appeared to reach a maximal value of 52 pmoles per hr per 10(9) cells at an external concentration of about 13 mum. Correspondingly, the rate of inhibition of mycolic acid synthesis increased with the rise in the rate of uptake of the drug. A 50% inhibition of mycolic acid synthesis occurred when the uptake of isoniazid reached 5.2 pmoles per 10(9) cells. Calculations showed that this level of drug uptake represents an internal cellular concentration of 9 mum. These results show clearly that the action of isoniazid on the mycolate synthetase system of M. tuberculosis is rapid and that this enzyme system is highly sensitive to the drug.

Abstract
When an actively growing culture of the H37Ra strain of Mycobacterium tuberculosis was exposed to isoniazid at a concentration of 0.5 mug/ml, the cells began to lose their ability to synthesize mycolic acids immediately. After 60 min, the cells had completely lost this ability. The synthesis of the three mycolate components-alpha-mycolate, methoxymycolate, and beta-mycolate-was inhibited. The viability of the isoniazid-treated cells was unaffected up to about 60 min of exposure, after which time there was a gradual decline in the viability to about 18% after 180 min. Correspondingly, growth of the drug-treated cells slowed down and stopped after 24 hr. The inhibition of the synthesis of mycolic acids was reversible if the drug was removed before the loss of viability set in. Incubation of the viable cells in the absence of the drug for 24 hr restored the mycolate synthesis. These results strongly suggest that the inhibition of the synthesis of the mycolic acids is closely associated with the primary mechanism of action of isoniazid on the tubercle bacilli. The sequence of events which leads to the loss of viability of cells exposed to isoniazid is described.

Abstract
The antibiotic d-cycloserine inhibits the synthesis of the wax D peptidoglycolipid in cells of the H37Ra strain of Mycobacterium tuberculosis. This inhibition occurs at a lower concentration of the drug than that required for the inhibition of growth. The inhibition is completely reversed by d-alanine. An arabino-galactan-galactosamine-(diaminopimelic acid)-mycolate accumulates in H37Ra cells exposed to the antibiotic. The chemical and functional group analyses of this lipid suggests it to be a possible precursor to the synthesis of wax D.
