Fusobacterium necrophorum: its characteristics and role as an animal pathogen.

Tonsillar colonisation of Fusobacterium necrophorum in patients subjected to tonsillectomy

BACKGROUND Fusobacterium necrophorum is a well-known cause of Lemirre's disease and accumulating evidence support its pathogenic role in peritonsillar abscess while its role in recurrent and chronic tonsillitis is uncertain. The objective of this study was to assess the prevalence of oropharyngeal colonisation with F. necrophorum and Beta-haemolytic streptococci in a cohort of patients schedule...

Factor H binding as a complement evasion mechanism for an anaerobic pathogen, Fusobacterium necrophorum.

Fusobacterium necrophorum subspecies funduliforme is an obligate anaerobic Gram-negative rod causing invasive infections such as the life-threatening Lemierre's syndrome (sore throat, septicemia, jugular vein thrombosis, and disseminated infection). The aim of our study was to understand if and how F. necrophorum avoids C activation. We studied 12 F. necrophorum subsp. funduliforme strains isol...

Fusobacterium necrophorum, an emerging pathogen of otogenic and paranasal infections?

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...

First study of pathogen load and localisation of ovine footrot using fluorescence in situ hybridisation (FISH)

Analysis of bacterial populations in situ provides insights into pathogen population dynamics and potential reservoirs for disease. Here we report a culture-independent study of ovine footrot (FR); a debilitating bacterial disease that has significant economic impact on sheep farming worldwide. Disease begins as an interdigital dermatitis (ID), which may then progress to separation of the hoof ...
