Microbiology of Para- og Retropharyngeal Abscess

The aims of the study are: 1. Explore the bacteriology of para- and retropharyngeal abscess. 2. Validate the bacterial findings by exploring antibody development against F. necrophorum, F. nucleatum and S. pyogenes. 3. Compare bacteriologic findings in concomitant peritonsillar and parapharyngeal abscesses. 4. Characterize patients with para- and retropharyngeal abscess. 5. Compare the concentration of amylase in para- and retropharyngeal abscesses and neck abscesses without relation to the pharynx or salivary glands. 6. Perform gene-sequencing of F. Necrophorum strains, and compare these with strains recovered from patients with acute tonsillitis, peritonsillar abscess, and Lemierre´s syndrome.
