Tonsillitis is inflammation (swelling) of the tonsils.
Causes, incidence, and risk factors
The tonsils are lymph nodes in the back of the mouth and top of the throat. They normally help to filter out bacteria and other germs to prevent infection in the body.
Strep throat is one cause of tonsilitis.
The tonsils may become so overwhelmed by a bacterial or viral infection that they swell and become inflamed, causing tonsillitis. The infection may also be present in the throat and areas around it, causing inflammation of the pharynx. The pharynx is in the back of the throat, between the tonsils and voicebox (larynx). See: Pharyngitis
Tonsillitis is very common, especially in children.

The number of tonsillectomies began to decline in the sixties. The sore throats and colds, for the most part, disappeared as the child grew older, and tonsil removal was no longer deemed necessary.
Now, however, tonsillectomies are back in favor as a treatment for sleep apnea in children. As well as being a cause of sore throats and colds, enlarged tonsils block the air passages causing nighttime breathing problems. Other problems caused by enlarged tonsils are problems swallowing, fever and swollen glands.

Unfortunately, when tonsils become infected, they swell and cause even further problems, including sore throat and tonsillitis . If...

Group B streptococcal septicemia is caused by the bacterium Streptococcus agalactiae , which is commonly called "group B strep" or GBS. A newborn with septicemia is very sick. GBS is commonly found in adults and older children, where it does not usually cause infection. There are two ways in which it may be passed to a newborn baby: The infant can become infected as he or she passes through the birth canal. In this case, babies become ill between birth and 6 days of life (most often in the first 24 hours). This is called "early-onset" GBS disease. The infant may also become infected after delivery by coming into contact with people who carry the GBS germ. In this case symptoms appear late...
