Fusobacterium necrophorum leukotoxin induces activation and apoptosis of bovine leukocytes.
Fusobacterium necrophorum, a gram-negative, rod-shaped, anaerobic bacterium, is a primary or secondary etiological agent in a variety of necrotic, purulent infections in humans and animals. Its major virulence factor is leukotoxin, a high-molecular-weight secreted protein, primarily toxic to ruminant leukocytes. In this study, bovine peripheral blood leukocytes were exposed to various concentra...
متن کاملSelective enumeration of Fusobacterium necrophorum from the bovine rumen.
A culture medium containing lactate as the sole energy source and antibiotics (bacitracin, gentamicin, and streptomycin) was used for selection and enumeration of Fusobacterium necrophorum from bovine ruminal contents. F. necrophorum growth was determined by indole production, and enumeration was performed by the most-probable-number technique. The number of F. necrophorum cells in cattle fed a...
متن کاملHuman infections with Fusobacterium necrophorum.
Fusobacterium necrophorum is a Gram-negative anaerobic bacillus that can be a primary pathogen causing either localised abscesses and throat infections or systemic life-threatening disease. Systemic infections due to F. necrophorum are referred to as either Lemierre's disease/syndrome, post-anginal sepsis or necrobacillosis, but in the context of this mini-review, all are included under the umb...
متن کاملEffects of limonene on ruminal Fusobacterium necrophorum concentrations, fermentation, and lysine degradation in cattle1
Previous in vitro data showed that Fusobacterium necrophorum was inhibited by limonene. We further evaluated effects of limonene on growth of F. necrophorum in vitro as well as on ruminal concentrations of F. necrophorum in vivo. With in vitro cultivation in anaerobic brain-heart infusion broth, limonene decreased growth of F. necrophorum. Thymol also reduced growth of F. necrophorum, but it wa...
متن کاملDisseminated intravascular coagulation in Fusobacterium necrophorum septicemia.
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...
