Summary Introduction
To determine:
The purpose that Haemophilus use the growth factors, when members of the pathogenic bacterial genus Haemophilus require NAD+ and heme from their environment.
Introduction:
The pathogens are the microorganisms which require NAD and heme groups for the proper growth in pathogens. The NAD+ is the nicotinamide adenine dinucleotide which is used as a coenzyme in various reactions.

Pathways include the complete glycolytic pathway, the citric acid cycle and Electron Transport System . Amino acid biosynthesis and the production of purines are complete, however of the pyrimidines, the cytidine production pathway lacks the final cytidine triphosphate synthetase, hence, cytidine cannot be synthesized. In order for C. diphtheriaeto to colonize the host, it needs this pyrimidine base. What is this nutrient requirement called, and from where does the bacterium obtain it?
Single celled organisms that grow in irregular masses and include molds mildews and yeasts?
How does an abundance of tryptophan inhibit the production of more tryptophan?
Sydney Brenner isolated Salmonella typhimurium mutants that were
implicated in the biosynthesis of tryptophan and would not grow on
minimal medium. When these bacterial mutants were tested on minimal
medium to which one of four compounds (indole glycerol phosphate,
indole, anthranilic acid, and tryptophan) had been added, the growth
responses shown in the following table were obtained.
