BACKGROUND Fusobacterium species (spp.) bacteremia is uncommon and has been associated with a variety of clinical presentations. We conducted a retrospective, population based study to determine the relative proportion of species in this genus causing bacteremia and the risk factors for infection and adverse clinical outcomes. METHODS All cases of Fusobacterium spp. bacteremia detected at a r...

The recent WHO report on antibiotic resistances shows a dramatic increase of microbial resistance against antibiotics. With only a few new antibiotics in the pipeline, a different drug delivery approach is urgently needed. We have obtained evidence demonstrating the effectiveness of a cell based drug delivery system that utilizes the innate immune system as targeting carrier for antibacterial d...

OBJECTIVES Although most susceptibility studies for linezolid have investigated aerobic bacteria, only a few have investigated anaerobe isolates. The aim of the present study was to determine the antibacterial activity of linezolid against a larger sample of clinical isolates of Fusobacterium spp. and to report on the detailed susceptibility, stratified by species. METHODS The in vitro suscep...

The phylogenetic interrelationships of 14 members of the genus Fusobacterium were investigated by performing a comparative analysis of the 16S rRNA sequences of these organisms. The sequence data revealed considerable intrageneric heterogeneity. The four species Fusobacterium nucleatum (including F. nucleatum subsp. nucleatum, F. nucleatum subsp. polymorphum, "F. nucleatum subsp. fusiforme," an...

Abstract The Fusobacterium genus contains Gram-negative, rod-shaped anaerobic bacteria. necrophorum and its two subspecies, funduliforme, are normal ruminal inhabitants of cattle. Subsp. is the primary causative agent liver abscesses in feedlot varium also a rumen inhabitant, but role fermentation involvement unknown. Currently, no PCR assays exist to quantify F. both subspecies necrophorum. Th...

A previously healthy 42-year-old man developed, after a neglected tonsillitis, a severe Fusobacterium necrophorum septicemia with disseminated intravascular coagulation. Peripheral, painful, cyanotic and gangrenous lesions appeared on toes, external ears and nose tip. The patient survived. Consumption coagulopathy associated with tonsillitis should suggest F. necrophorum infection. Growth of th...

Fusobacterium necrophorum is a rare causative agent of otitis and sinusitis. Most commonly known is the classic Lemièrre's syndrome of postanginal sepsis with suppurative thrombophlebitis of the jugular vein. We report five patients diagnosed recently with a complicated infection with F. necrophorum originating from otitis or sinusitis. Two patients recovered completely, one patient died due to...

Lemierre syndrome is defined by septic thrombophlebitis of the internal jugular vein caused by Fusobacterium. Historically, these infections originate from the oropharynx and typically are seen in older children, adolescents and young adults. More recently, otogenic sources in younger children have been described with increasing frequency. We present a case of a two-year old, who initially deve...
