This causes pharyngitis and 'pseudomembrane' in the throat. The strains that are toxigenic are ones which have been infected with a bacteriophage. [11] [12] The diphtheria toxin gene is encoded by the bacteriophage found in toxigenic strains, integrated into the bacterial chromosome. [13] The diphtheria toxin repressor is mainly controlled by iron.

The laryngopharynx, (Latin: pars laryngea pharyngis), also known as hypopharynx, is the caudal part of the pharynx; it is the part of the throat that connects to the esophagus. It lies inferior to the epiglottis and extends to the location where this common pathway diverges into the respiratory ( laryngeal ) and digestive ( esophageal ) pathways.
