dermonecrotic activity of a cell wall preparation from fusobacterium necrophorum.a cell wall preparation of fusobacterium necrophorum induced haemorrhagic necrosis in the skins of guinea pigs and rabbits. effects in mice and rats were weak or absent. the toxic activity of the cell wall preparation was not reduced by heat treatment. a dermonecrotic toxin was isolated from the cell wall preparation with sodium dodecylsulphate and concentrated by precipitation with ethanol. a preparation of the bacterial cytoplasm from fus. necrophorum induced mainly erythema.19957766069
lemierre's syndrome: two cases of postanginal sepsis.lemierre's disease consists of suppurative thrombophlebitis of the ijv in the presence of oropharyngeal infection and can be complicated by septic pulmonary emboli. if a patient has an oropharyngeal or deep neck infection and neck pain suspicious for ijv thrombosis, a ct or mri is warranted to establish the diagnosis. blood cultures should be obtained to establish the responsible organism. in most cases f. necrophorum, an anaerobic bacterium, is responsible for the sepsis. once the diagnosis of ...19957777368
the circulatory effects of an acute infusion of anaerobes in a rabbit model.results of this study show that an acute infusion of bacteroides fragilis into a rabbit model is associated with a transitory and minimal lowering of mean arterial pressure. peak left ventricular systolic pressure and its first derivative decreased significantly, but these abnormalities lasted for less than three minutes. by contrast, an infusion of fusobacterium necrophorum is associated with a profound depression of mean arterial pressure, left ventricular systolic pressure and its first deriv ...19807444724
[a case of fusobacterium necroforum sepsis].a 26-year-old man was admitted to our hospital with a 10-day history of sore throat, high fever, and right knee joint pain. on physical examination, the pharynx was considerably inflamed, and the right knee joint was swollen and extremely tender. chest radiography showed multiple, bilateral nodules and masses with pleural effusions. fusobacterium necorforum grew from samples of blood, pleural effusion, and pus taken from the knee joint. the patient was treated with intravenous clindamycin, venti ...19947815762
[multiple liver abscesses caused by fusobacterium necrophorum infection].a case of multiple liver abscesses caused by fusobacterium necrophorum infection is presented. in cases with fever of unknown origin and biochemical signs of derangement of hepatic function, it is recommended that an abdominal scan is performed. before initiating antibiotic treatment relevant specimens should be collected. finally we describe how the use of resin-containing blood culture medium enhance the possibility of bacterial detection in patients receiving antibiotics.19947839488
necrobacillosis--an unusual case of pharyngotonsillitis.necrobacillosis is a potentially life-threatening septicaemic illness occurring in the previously fit and healthy. the authors illustrate a case presenting as an atypical pharyngotonsillitis with renal complications, initially misdiagnosed as poststreptococcal glomerulonephritis. necrobacillosis should be considered in cases of unusual pharyngotonsillitis.19947861093
purification and quantification of fusobacterium necrophorum leukotoxin by using monoclonal antibodies.monoclonal antibodies (mabs) were produced to the leukotoxin of fusobacterium necrophorum. two mabs (f7b10 and e12e9) partially neutralized leukotoxin activity, as determined by a tetrazolium (mtt)-dye reduction assay with bovine polymorphonuclear neutrophils as target cells. immunoblot analysis showed that both clones reacted with antigens of 110 and 131 kilodaltons. epitope analysis showed that the two mabs recognized the same epitope. an affinity column containing immobilized mab f7b10 was us ...19947886927
fatty acids and neutral sugars present in lipopolysaccharides isolated from fusobacterium species.lipopolysaccharides (lps) extracted from cells of fusobacterium necrophorum, f. mortiferum, f. gonidiaformans. varium and single strains of f. naviforme and f. russi were analysed for sugars and fatty acids. all preparations contained a monosaccharide tentatively identified as l-glycero-d-mannoheptose, but showed variation with respect to the presence of glucose, galactose, rhamnose and another heptose isomer, tentatively identified as l-glycero-d-mannoheptose. l-glycero-d-mannoheptose was a mon ...19807376878
studies on the factors affecting the hemolytic activity of fusobacterium necrophorum.the in vitro activity of the hemolysin of fusobacterium necrophorum was determined using the hemolysis of horse erythrocytes as an assay. the effects of medium composition and ph on hemolysin production were investigated. calf serum and casitone stimulated a comparatively higher hemolytic activity in f. necrophorum subsp. necrophorum and f. necrophorum subsp. funduliforme, respectively. however, sugars, such as glucose, galactose and fructose were inhibitors of hemolytic activity. the spectrum o ...19947801514
necrobacillosis revisited. 19948000683
biological and biochemical characterization of fusobacterium necrophorum leukotoxin.biological and biochemical characteristics of the leukotoxin of fusobacterium necrophorum were determined. culture supernatant of f necrophorum was toxic to polymorphonuclear neutrophilic leukocytes from cattle and sheep, but not to those from pigs and rabbits. culture supernatant and sonicated bacterial cell fractions had low hemolytic activity and did not cause dermonecrosis in a guinea pig. supernatant-derived leukotoxin was inactivated at 56 c for 5 minutes and became unstable at ph > 7.8 or ...19948017697
selective 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 100% forage diet was 7 x 10(5)/g of ruminal contents. the number increased (p < 0.05) 10-fold after th ...19948017925
mastoiditis, meningitis and venous sinus thrombosis caused by fusobacterium necrophorum.the authors report a case of septic venous sinus thrombosis (vst) and meningitis occurring as an early complication of mastoiditis caused by fusobacterium necrophorum. ct scan was normal, and cerebral angiography was required to diagnose the vst. the evolution was favourable with appropriate antimicrobial therapy and steroids.19948033922
