A case of strep throat. Streptococcal pharyngitis or strep throat is caused by a group A beta-hemolytic streptococcus (GAS). [20] It is the most common bacterial cause of cases of pharyngitis (15–30%). [19] Common symptoms include fever, sore throat, and large lymph nodes. It is a contagious infection, spread by close contact with an infected ...
Streptococcal pharyngitis, also known as streptococcal sore throat (strep throat), is pharyngitis (an infection of the pharynx, the back of the throat) caused by Streptococcus pyogenes, a gram-positive, group A streptococcus. [9] [10] Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the front
In this condition there can be inflammation of the linings of the trachea. A condition called tracheo-bronchitis can be caused, when the mucous membrane of the trachea and bronchi swell. A collapsed trachea is formed as a result of defect in the cartilage, that makes the cartilage unable to support the trachea and results in dry hacking cough.
It is not known whether antibiotics are effective for preventing recurrent sore throat. [14] There is only limited evidence that a hot drink can help alleviate a sore throat, and other common cold and influenza symptoms. [15] If the sore throat is unrelated to a cold and is caused by, for example, tonsillitis, a cold drink may be helpful. [16]
Vincent's angina (also termed Plaut–Vincent's angina), [1] [2] is pharyngitis (inflammation of the pharynx) and tonsillitis (inflammation of the palatine tonsils), caused by infection with two types of bacteria called fusiform (Fusobacterium spp.) [3] and spirochaetes (Borrelia spp. [3] and Spirillum spp.). [4]
Inflammation of the epiglottis is known as epiglottitis. Epiglottitis is mainly caused by Haemophilus influenzae. A person with epiglottitis may have a fever, sore throat, difficulty swallowing, and difficulty breathing. For this reason, acute epiglottitis is considered a medical emergency, because of the risk of obstruction of the pharynx.
Infections typically begin in the throat or skin. The most striking sign is a strawberry-like rash. Examples of mild S. pyogenes infections include pharyngitis (strep throat) and localized skin infection . Erysipelas and cellulitis are characterized by multiplication and lateral spread of S. pyogenes in deep layers of the skin.
Epiglottitis is the inflammation of the epiglottis—the flap at the base of the tongue that prevents food entering the trachea (windpipe). [7] Symptoms are usually rapid in onset and include trouble swallowing which can result in drooling, changes to the voice, fever, and an increased breathing rate.
