Diphtheria (Corynebacterium diphtheriae)

Corynebacteria are Gram-positive, aerobic, nonmotile, rod-shaped bacteria related to the Actinomycetes. They do not form spores or leg as do the actinomycetes, plain they ware the characteristic of forming freedom fighter shaped, club-shaped or V-shaped arrangements in everyday growth. They endure snapping movements just later cell division which brings them into characteristic arrangements resembling Chinese letters. The genus Corynebacteria consists of a respective(a) group of bacteria including savage and plant pathogens, as well as saprophytes. Some corynebacteria are disclose of the normal flora of worldly concern, finding a suitable niche in virtually every anatomic site. The best known and most wide canvas species is Corynebacterium diphtheriae, the causal talk terms of the distemper diphtheria. History and Background No bacterial disease of humans has been as success plenteousy see as diphtheria. The etiology, mode of transmission, unhealthful mechanism and molecular(a) terra firma of exotoxin structure, function, and bodily process have been clearly established. Consequently, highly effective methods of discourse and prevention of diphtheria have been developed. The study of Corynebacterium diphtheriae traces closely the development of medical microbiology, immunology and molecular biology. Many contributions to these fields, as well as to our soul of host-bacterial interactions, have been made studying diphtheria and the diphtheria toxin. Hippocrates provided the starting clinical description of diphtheria in the quaternate century B.C.

There are besides references to the disease in superannuated Syria and Egypt. In the 17th century, murderous epidemics of diphtheria brush Europe; in Spain El garatillo (the strangler), in Italy and Sicily, the gullet disease. In the 18th century, the disease reached the American colonies and reached epidemic proportions in 1735. Often, unhurt families died of the disease in a few weeks. The bacterium that caused diphtheria was first described by Klebs in 1883, and was cultivated by Loeffler in 1884, who utilize Kochs postulates and properly identified Corynebacterium...
