Additionally, it produces a variety of exotoxins, including leukocidin, hemolysin, lipase, and cytoplasmic toxin, all of which likely contribute to its pathogenicity. 2019-01-08 · The bacteria most commonly responsible for Lemierre syndrome is Fusobacterium necrophorum (F. necrophorum). 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. We argue that F. necrophorum is an important pathogen involved in pharyngotonsillitis in the age group of 13–40 years of age and we urge clinical microbiology labs to set up the appropriate techniques to be able to detect F. necrophorum from throat swabs.
}, author = {Holm, Karin and Bank, Steffen and Nielsen, Hanne and Kristensen, Lena Hagelskjær and Prag, Jørgen and Jensen, Anders F.necrophorum is a pathogenic, anaerobic, non-spore-forming Gram-negative bacteria; it is a normal inhabitant of the mammalian gut and cannot invade normal tissue.
Within the last decade, Fusobacterium necrophorum subsp. funduliforme has been considered a clinically important pathogen causing pharyngitis especially in adolescents and young adults. F. necrophorum pharyngitis can progress into Lemierre's syndrome, which is a severe and life-threatening infection. F. necrophorum is unique among non-spore-forming anaerobes, first for its virulence and association with Lemierre's syndrome as a monomicrobial infection and second because it seems probable that it is an exogenously acquired infection. The source of infection is unclear; suggestions include acquisition from animals or human-to-human transmission.

F.necrophorum is a primary pathogen in various diseases of farm animals. It forms mixed bacterial infections and can be secondary to IBR. Extracellular haemolysin contributes to infection and heat-stable leucocidin is correlated with biotype and virulence. Cytoplasmic toxin is haemolytic and LPS endotoxin causes host damage. F necrophorum is one of the commonest cause. Lemierre syndrome (postanginal sepsis): septic thrombophlebitis of the internal jugular vein. 80% of Lemierre syndrome are due to F necrophorum.
