DIPHTHERITIC MEMBRANE Meaning and
Definition
-
A diphtheritic membrane refers to a thick, grayish-white or yellowish-white film or layer that commonly forms in the respiratory tract, particularly in the throat and tonsils, as a result of diphtheria infection. Diphtheria is an infectious disease caused by the bacterium Corynebacterium diphtheriae. When this bacterium infects the throat, it releases a toxin that leads to the formation of a tough, fibrinous membrane.
The diphtheritic membrane typically adheres tightly to the affected tissues, making it challenging to remove. It can obstruct the airway and cause severe breathing difficulties. Moreover, the membrane may rapidly spread to nearby areas, such as the larynx and trachea, worsening the respiratory obstruction.
The membrane itself is composed of dead cells, fibrin, and bacterial colonies. Its presence is a characteristic feature of diphtheria, and its coloration is due to the accumulation of dead tissue and bacteria.
Prompt medical intervention is crucial when a diphtheritic membrane is present, as it poses a significant threat to the individual's life. Treatment often involves administering diphtheria antitoxin, which helps neutralize the effect of the bacterial toxin. Antibiotics are also commonly prescribed to eliminate the bacteria. In severe cases, a procedure called tracheostomy may be necessary to create an alternate airway.
The formation of a diphtheritic membrane is a defining aspect of diphtheria, distinguishing it from other respiratory infections.

Etymology of DIPHTHERITIC MEMBRANE
The etymology of the word "diphtheritic" can be traced back to the Greek word "diphthera", meaning "hide" or "leather". This term was used to describe a false membrane or layer that forms in the throat during the illness known as diphtheria. The word "diphtheritic" is derived from this Greek term, indicating the presence of or relating to such a membrane. The term "membrane" itself comes from the Latin word "membrana", meaning "parchment". Thus, the term "diphtheritic membrane" refers to the characteristic layer or patch formed in the throat during diphtheria.
