Overview
Diphtheria can be classified according to the type of Corynebacterium that causes it. It can also be divided according to the clinical presentation it results into: respiratory, systemic or cutaneous diphtheria.
Classification
Diphtheria infection an be classified according to the causative agent or the clinical manifestations of the infection.
Causative Agent
Diphtheria can be caused by several Corynebacterium species, which include:[1][2]
- Corynebacterium diphtheria, which can be further divided into 4 types based on morphologic and biochemical properties into:[3]
- Var. gravis
- Var. mitis
- Var. belfanti
- Var. intermedius
- Corynebacterium ulcerans
- Corynebacterium hemolyticum
- Corynebacterium pseudotuberculosis
Clinical Manifestations
Diphtheria infection can present in several ways, which include:[4]
- Respiratory diphtheria, which may also be divided into nasal, pharyngeal and laryngeal diphtheria[5]
- Systemic diphtheria, which results from the dissemination of diphtheria toxin into the heart[6][7], kidneys and nervous system[5]
- Cutaneous diphtheria, which is caused by toxigenic and non-toxigenic strains of Corynebacterium diphtheria[8]
