Diphtheria (Corynebacterium diphtheriae) Corynebacteria are Gram-positive, aerobic, nonmotile, rod-shaped bacteria related to the Actinomycetes. They do not form spores or branch as do the actinomycetes, but they have the characteristic of forming irregular shaped, club-shaped or V-shaped arrangements in normal growth. They undergo snapping movements just after cell division which brings them into characteristic arrangements resembling Chinese letters. The genus Corynebacterium consists of a diverse
environment. Due to the modern understanding of the transmission and composition along with the development of a vaccine; it has brought us a long way of avoiding this disease. Diphtheria is caused by a pathogenic (disease causing) bacterium called Corynebacterium diphtheria also known as C. diphtheria (Nordqvist, 2004-2014). This bacterium usually effects the upper respiratory tract where inflammation is contracted. In a serious matter or event, this pathogen can be deadly once it enters the blood stream
