A peritonsillar abscess (PTA), also known as a quinsy, is an accumulation of pus due to an infection behind the tonsil. [2] Symptoms include fever, throat pain, trouble opening the mouth, and a change to the voice. [1] Pain is usually worse on one side. [1] Complications may include blockage of the airway or aspiration pneumonitis. [1]
F. necrophorum is responsible for 10% of acute sore throats, [4] 21% of recurrent sore throats [5] [6] and 23% of peritonsillar abscesses [7] with the remainder being caused by Group A streptococci or viruses.
Lemierre's syndrome occurs most often when a bacterial (e.g., Fusobacterium necrophorum) throat infection progresses to the formation of a peritonsillar abscess. Deep in the abscess, anaerobic bacteria can flourish. When the abscess wall ruptures internally, the drainage carrying bacteria seeps through the soft tissue and infects the nearby ...
F. necrophorum has been found as a common pathogen in the diagnostic of peritonsillar abscess and is more prevalent than other bacteria regarding this infection. It is also the most frequent leading cause associated with Lemierre Syndrome and is not proven to be a normal part of the human oral bacterium population. [ 8 ]
These include tonsillar, [14] peritonsillar and retropharyngeal abscesses, chronic otitis media, sinusitis and mastoiditis, eye ocular) infections, [15] all deep neck space infections, parotitis, sialadenitis, thyroiditis, odontogenic infections, and postsurgical and nonsurgical head and neck wounds and abscesses.

Submandibular and peritonsillar abscesses caused by E. corrodens can be treated by incision and drainage. [18] Earlier diagnosis and proper drainage surgery with effective antibiotics treatment may improve the prognosis. [19] First-choice drugs for E. corrodens infections should be third-generation cephems, carbapenems, or new quinolones. [20]

Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. [9] As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. [9]
