Causes of tonsillitis
The common causes of tonsillitis are the viral infections or may be the bacterial ones. This condition is caused by the bacteria named Streptococcus pyogenes, also known as group A streptococcus. This bacterium is the culprit to be blamed for most of the strep throat cases. Certain kinds of white blood cells are produced by the tonsils, and these WBCs are used to fight the disease causing germs that enter the oral cavity. Tonsils are, thus, know to act as the first line of defense on behalf of the immune system of the body. This act if charity for the body, which is a necessary and appraisable one, leads the tonsils to the doorsteps of vulnerability. The tonsils become susceptible towards the various throat infections and inflammations. The immune system function of the tonsils diminishes to zero, gradually, after puberty. Hence, there are quite rare cases of tonsillitis in adult population.
