[Sepsis due to fusobacteria in a young adult].

Fusobacteria belong to the normal population of the pharyngeal mucosa as well as the mucosa of the upper airways and the gastrointestinal tract. Infections are comparatively rare. The most common causative organism is Fusobacterium necrophorum. A well-known infection caused by this germ is Lemierre's syndrome. In the presented case, a 19-year-old man (123 kg body weight, 186 cm body length) was found dead in his bed in the morning after having complained of muscular fatigue and vomiting the previous day. Autopsy was carried out only two days after death. At that time, the body showed marked putrefaction with partial greenish discoloration and marbling of the skin although it had been stored in a refrigerator at +2 degrees C in the meantime. While the autopsy itself revealed no cause of death, microbiological examination of a smear from the left lower pulmonary lobe demonstrated Staphylococcus aureus and Fusobacterium necrophorum. Toxicological investigations produced negative results throughout. The cause of death was defined as sepsis caused by Fusobacterium necrophorum.
