C. DIPHTHERIAE II. SPECIFIC CHARACTERISTICS OF THE GROWTH CURVE OF C. DIPHTHERIAE

C. diphtheriae. II. Specific characteristics of the growth curve of C. diphtheriae.

In a previous publication evidence was presented for the conclusion that biochemical activity of C. diphtheriae during the growth phase should be differenciated from those of other bacilli(1). It seems to be rather contradictorious to say that chemical activities of this organism fall to the minimum lebel during its growth phase. This paper develops further the experimental and theoretical aspe...

Serological Classification of C. Diphtheriae in Calcutta

The Use of Pancreatic Extract as a Growth Stimulant for C. Diphtheriae.

mer, had a markedly stimulating effect on the growth of C. diphtheriae and that they retained this power even after the digestive enzyme content had been inactivated by heat. The active principle in the pancreatic extract is water-soluble, passes readily through a collodion membrane, and is thus of low molecular weight. Further investigations were undertaken to determine whether pancreatic extr...

bacteriological typing of c. diphtheriae strains recently isolated in teheran

from a total of 600 nose and throat introduction swabs examined for diphtherie, 200 or 33% were positive. cultures were carfully classified on the basis of morphological appearance and biochemical characteristics into gravis, mitis and intermedius groups.  a special tellurite serum agar was used for colonial appearance. neill's broth culture was employed for haemolytic tests. the virulence of e...

Characterization of C-S Lyase from C. diphtheriae: A Possible Target for New Antimicrobial Drugs

The emergence of antibiotic resistance in microbial pathogens requires the identification of new antibacterial drugs. The biosynthesis of methionine is an attractive target because of its central importance in cellular metabolism. Moreover, most of the steps in methionine biosynthesis pathway are absent in mammals, lowering the probability of unwanted side effects. Herein, detailed biochemical ...
