| [thrombophlebitis of the cavernous sinus secondary to polysinusitis. report of a new case]. | cavernous sinus thrombophlebitis syndrome is uncommon nowadays. despite the wide range of antimicrobial agents it carries a high mortality. the disease frequently arises from infection of face, mouth, nose and paranasal sinuses, reaching the cavernous sinus by venous spread. involvement of adjacent anatomic structures accounts for most of the clinical findings. meningeal involvement, bilateral orbital edema and ocular cranial nerves palsy are very helpful in the differential diagnosis. streptoco ... | 1995 | 7734168 |
| [neck pyomyositis associated with polymicrobial sepsis of sinusal origin]. | spontaneous pyomyositis (primary pyomyositis) is an infrequent disease in non-tropical countries, caused by bacterial infection of skeletal muscle. although pyomyositis is associated in many cases to septicemia, the occurrence of that disease as a secondary manifestation of bacteremia is very unusual, requiring a high-grade index of suspicion to diagnose it in the early stages. we present one case of cervical pyomyositis, caused by fusobacterium necrophorum and group f streptococcus, during the ... | 1994 | 7734667 |
| 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. | 1995 | 7766069 |
| 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 ... | 1995 | 7777368 |
| 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 ... | 1994 | 7801514 |
| [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 ... | 1994 | 7815762 |
| [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. | 1994 | 7839488 |
| 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. | 1994 | 7861093 |
| 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 ... | 1994 | 7886927 |
