The bacteria may cause invasive disease by releasing toxins into surrounding tissue. F. necrophorum är ansvarig för 10% av akuta halsont , 21% av återkommande ont i halsen och 23% av peritonsillar abscesser, medan resten orsakas av grupp A streptokocker eller virus . Andra komplikationer från F. necrophorum inkluderar hjärnhinneinflammation , komplicerad av trombos i den inre halsvenen, trombos i hjärnvenerna och infektion i urogenitala och mag- tarmkanalen. F. necrophorum contains particulary powerful endotoxic lipopolysaccharides in its cell wall and produces a coagulase enzyme that encourages clot formation. Additionally, it produces a variety of exotoxins, including leukocidin, hemolysin, lipase, and cytoplasmic toxin, all of which likely contribute to its pathogenicity.

F. necrophorum subsp. necrophorum (formerly F. necrophorum bio-type A) is the principal pathogen of cattle (causing liver abscesses, foot rot, and calf diphtheria), whereas F.necrophorumsubsp. fun- F. necrophorum. Fusobacterium necrophorum is the species of Fusobacterium that is responsible for Lemierre's syndrome, and appears to be responsible for 10% of all acute sore throats and 21% of all recurring sore throats, with the remainder being caused by Group A streptococci or viruses. 2009-05-01 2016-11-01 F. necrophorum is classified into subsp.

Fusobacterium necrophorum är det orsakande ämnet hos dem som drabbas av Under den ursprungliga infektionen tar F necrophorum över infektionsplatsen av J Hedenmark · 2018 — Fusobacterium necrophorum is the most common pathogen.

This bacteria is normally present in healthy people in various parts of the body (including the throat, digestive tract, and female genitals). The bacteria may cause invasive disease by releasing toxins into surrounding tissue. Fusobacterium necrophorum is a Gram-negative obligate anaerobe commonly associated with peritonsillar abscesses, tonsillitis, and Lemierre's syndrome, a rare life-threatening complication of oropharyngeal infection (1, 2). F. necrophorum contains particulary powerful endotoxic lipopolysaccharides in its cell wall and produces a coagulase enzyme that encourages clot formation. Additionally, it produces a variety of exotoxins, including leukocidin, hemolysin, lipase, and cytoplasmic toxin, all of which likely contribute to its pathogenicity.

F. necrophorum is traditionally described as forming part of the normal flora of the oropharynx, gastrointestinal tract and genitourinary tract of humans, but convincing evidence is lacking [ … 2017-04-01 F. necrophorum is a gram-negative anaerobic bacterium that is difficult to grow on routine media from throat swabs. Blood cultures grow the organism, but identification is slow.

Characteristics. F.necrophorum is pleimorphic and is either long and filamentous or a short cocci. It is fermentative and haemolytic on blood agar.
