Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [ 4 ] [ 5 ] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans.
However, the application of novel molecular biological techniques to taxonomy has established a number of new species, together with the subspeciation of Fusobacterium necrophorum and F. nucleatum, and provided new methods for identification. The involvement of Fusobacteriota in a wide spectrum of human infections causing tissue necrosis and ...
The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy. Vaginal flora can be transmitted to babies during birth. Vaginal dysbiosis can lead to vaginal infections like bacterial vaginosis which makes one relatively susceptible to sexually transmitted diseases.
Fusobacterium polymorphum is a subspecies of Fusobacterium nucleatum, which is a member of the phylum Fusobacteriota and family Fusobacteriaceae. [1] Having originally been grouped together with Bacteroides, as well as other Gram-negative anaerobes, advances in genetic analysis have made it clear that Fusobacterium are actually phylogenetically closer in relation to organisms such as those of ...
Vincent's angina (also termed Plaut–Vincent's angina), [1] [2] is pharyngitis (inflammation of the pharynx) and tonsillitis (inflammation of the palatine tonsils), caused by infection with two types of bacteria called fusiform (Fusobacterium spp.) [3] and spirochaetes (Borrelia spp. [3] and Spirillum spp.). [4]
This is explained by a greater number of anaerobic bacteremia in patients with complex underlying disease or those that are immunosuppressed. The commonest isolates are B. fragilis group (over 75% of anaerobic isolates), Clostridium spp. (10–20%), Peptostreptococcus spp. (10–15%), Fusobacterium spp. (10–15%) and P. acnes (2–5% ...
Fusobacterium necrophorum is a species of bacteria responsible for Lemierre's syndrome. It has also been known to cause sinusitis, mastoiditis, ...
