characterization, distribution, and microbiological associations of fusobacterium spp. in clinical specimens of animal origin.during the years from 1984 through 1991, 1,067 specimens from canine, equine, exotic, feline, porcine, and ruminant animal sources were found to contain members of the genus fusobacterium: the most common sites or conditions from which members of this genus were isolated were abscesses, the respiratory tract, and pleural and peritoneal cavities. most specimens contained a single fusobacterium species. the most commonly isolated species was fusobacterium necrophorum. almost all of the specimens c ...19948150946
serum neutralizing antibodies against fusobacterium necrophorum leukotoxin in cattle with experimentally induced or naturally developed hepatic abscesses.the relationship between serum-neutralizing antibody against fusobacterium necrophorum leukotoxin and hepatic abscesses was investigated in cattle fed diets supplemented with or without tylosin. sixteen cattle (eight each in tylosin and in control groups) were inoculated intraportally with f. necrophorum. ultrasonographic scanning showed that all control animals developed hepatic abscesses after inoculation. in the tylosin group, two animals were free of abscess by d 7 and one was free by d 14. ...19948157537
phylogenetic relationship of fusobacterium necrophorum a, ab, and b biotypes based upon 16s rrna gene sequence analysis.the 16s rrna genes from virulent (ab) and benign (b) biotype strains of fusobacterium necrophorum, the causative agent of ovine foot abscess, were cloned and sequenced. notwithstanding the distinct phenotypic differences between the ab and b biotypes, a phylogenetic analysis in which the 16s rrna gene sequences were used revealed the close relationship of these taxa. comparison of the virulent and benign biotypes of f. necrophorum may therefore be a legitimate way to identify key virulence facto ...19948186096
delayed-type hypersensitivity in mice experimentally infected with fusobacterium necrophorum.the foot-pad test was performed to reveal the induction of delayed-type hypersensitivity (dth) to fusobacterium necrophorum in mice experimentally infected with f. necrophorum. for the foot-pad test, heat-killed cells of f. necrophorum were found to be better than viable bacteria as eliciting antigens. the thickness of foot-pad could be measured properly at 48 hr after administration to the foot-pad of heat-killed bacteria. an intraperitoneal dose of the order of 10(5) or 10(6) of viable bacteri ...19948204761
three cases of fusobacterium necrophorum septicemia.two cases of necrobacillosis or post-anginal septicemia (lemierre's syndrome) due to fusobacterium necrophorum are described. the first case in a young adult was complicated by thrombophlebitis of the internal jugular vein, lung abscesses and skin involvement. the second case was in a 2-year-old child, which is exceptional. the primary focus was possibly otitis media. in a third patient with multiple metastases of colon carcinoma, fusobacterium necrophorum septicemia was diagnosed during a bout ...19938243489

fusobacterium septic arthritis of the sternoclavicular joint.we describe a case of septic arthritis of the sternoclavicular joint caused by fusobacterium in an otherwise healthy young man. the fusobacterium had morphologic features most in keeping with fusobacterium (f.) necrophorum, which was a common organism in sternoclavicular septic arthritis in the preantibiotic era. to our knowledge this is the first reported case of a fusobacterium sternoclavicular joint infection in the antibiotic era. this case should lead to heightened awareness of sternoclavic ...19938308792
[acute mastoiditis due to anaerobic bacteria. review of the literature apropos of a case].the authors report a case of acute mastoiditis in a four year-old boy due to fusobacterium necrophorum. the importance of the complications (septiciemia, lateral sinus thrombosis, meningitis, osteitis) and the fusobacterium necrophorum are the two majors interests of this observation. a review of the literature is performed.19938317866
lemierre's syndrome caused by fusobacterium necrophorum: a case report. 19938320498
[diagnostic imaging in lemierre's+ syndrome].the lemierre syndrome is a septic picture with jugular thrombophlebitis and secondary septic embolisms usually produced by fusobacterium necrophorum. in previous reports published in the literature, imaging techniques are seldom referred to report the presence of jugular thrombophlebitis. a case of the lemierre syndrome is presented with the aim of calling attention to this process and its current diagnostic possibilities.19938324024
bacteriologic findings in peritonsillar abscesses in young adults.aspirated pus samples from 124 patients with peritonsillar abscess were cultured quantitatively for aerobes and anaerobes. a total of 98% of the samples yielded bacteria. of the 550 isolates obtained (mean, 4.4 per patient), 143 were aerobes (representing 16 species or groups) and 407 were anaerobes (representing 40 species or groups). aerobes were isolated from 86% of patients-alone in 20 cases and together with anaerobes in 87. the most common aerobic isolates were streptococcus pyogenes (isol ...19938324134
multiple brain abscesses and bacteremia in a child due to fusobacterium necrophorum.a case of fusobacterium necrophorum bacteremia and multiple brain abscesses in a 6-year-old child following a mycoplasma pneumoniae infection is described. brain abscess due to this microorganism has only been described in three other cases since 1977. the clinical picture was consistent with postanginal septicemia, with septic metastatic complications normally only seen in teenagers and young adults. the patient was successfully treated with a 2-month course of parenteral penicillin g and metro ...19938365815
partial characterization of hcl heat extracted antigen derived from fusobacterium necrophorum.the hcl heat extracted antigen derived from fusobacterium necrophorum was partially purified by cm cellulose column chromatography and treatment by freeze-thawing. it demonstrated relatively high enzyme-linked immunosorbent assay values to anti-f. necrophorum sera. in sodium dodecyl sulphate polyacrylamide gel electrophoresis, the partially purified preparation exhibited one definite and two faint bands. the approximate molecular weight of the former was estimated as 16 kd.19938366827

comparison of extracellular enzymes of fusobacterium necrophorum subsp. necrophorum and fusobacterium necrophorum subsp. funduliforme.a total of 10 strains each of fusobacterium necrophorum subsp. necrophorum and fusobacterium necrophorum subsp. funduliforme were tested for the production of 13 extracellular enzymes. dnase, alkaline phosphatase, and lipase were predominantly associated with all the strains of f. necrophorum subsp. necrophorum, with dnase not detected in any of the strains of f. necrophorum subsp. funduliforme. in addition, the strains of f. necrophorum subsp. necrophorum were generally more hemolytic than thos ...19938370761
fusobacteria: new taxonomy and related diseases.fusobacteria are anaerobic gram-negative bacilli. since the first reports in the late nineteenth century, various names have been applied to these organisms, sometimes with the same name being applied to different species. more recently, not only have there been changes to the nomenclature, but also attempts to differentiate between species which are believed to be either pathogenic or commensal or both. because of their asaccharolytic nature, and a general paucity of positive results in routine ...19938411084
lemierre syndrome: the forgotten disease.lemierre syndrome is characterized by an acute oropharyngeal infection, suppurative thrombophlebitis of the internal jugular vein, anaerobic sepsis, and metastatic infections. before the discovery of antibiotics, this disease usually was fatal. we report the case of a patient with all of these findings, indicating that lemierre syndrome still is seen today. prompt recognition, abscess drainage, and appropriate antibiotic coverage result in complete recovery in most patients.19938427443
meningitis due to fusobacterium necrophorum subspecies necrophorum. case report and review of the literature.this paper reports a case of fatal meningitis caused by fusobacterium necrophorum subsp. necrophorum in a previously healthy five-year-old child. the organism was isolated in pure culture from the cerebrospinal fluid and from intracranial pus obtained at autopsy. the role of f. necrophorum in the development of meningitis is reaffirmed and its isolation and identification are discussed. the clinical presentation of the present case resembles the previously published reports and highlights the po ...19938449585
structural studies of the o-antigenic polysaccharide of fusobacterium necrophorum.the o-specific polysaccharide component of the lipopolysaccharide produced by fusobacterium necrophorum is of the teichoic acid type, with repeating units connected by phosphoric diester linkages. dephosphorylation of the polysaccharide by treatment with aqueous hydrogen fluoride yielded a carbohydrate composed of a trisaccharide linked to an acidic component. this product, and the polysaccharide, were investigated by chemical methods and 1h-, 13c-, 31p- and 15n-nmr spectroscopy and the former a ...19938462551
the prevalence of fusobacterium necrophorum biovar a in animal faeces.only a small proportion of animals tested were found to be excreting fusobacterium necrophorum biovar a, the causative organism of necrobacillosis, in the faeces (3 of 69 wallabies, 1 of 66 deer, 2 of 81 cattle). the two positive cattle belonged to a single group of calves on a farm with a history of necrobacillosis and the litter underfoot also readily yielded biovar a organisms. all attempts to demonstrate biovar a in litter on other farms and in soil from an area populated by wallabies and de ...19938472776
effect of disturbance of the gastrointestinal microflora on the faecal excretion of fusobacterium necrophorum biovar a.oral pretreatment of mice with either a mixture of kanamycin and erythromycin or metronidazole to modify the gut microflora greatly enhanced the faecal excretion of fusobacterium necrophorum biovar a given by mouth. this lends support to the suggestion that disturbance of the gastrointestinal microflora in animals such as cattle, which often carry the organism in the rumen, may lead to intestinal multiplication and faecal excretion, thereby providing a source of infection that may lead to necrob ...19938472777
adult respiratory distress syndrome as a complication of postanginal sepsis.adult respiratory distress syndrome (ards) was described in 1971 by petty and ashbaugh. since that time it has been reported in association with many disease entities. we report a case in which a patient with postanginal sepsis, also known as lemierre's syndrome, had development of ards.19938486067
[postanginal sepsis caused by fusobacterium necrophorum: lemierre syndrome].postanginal sepsis or lemierre's syndrome is characterised by septic thrombophlebitis of the jugular vein, metastatic abscesses in the lungs, soft tissues, joints or elsewhere, occurring several days to two weeks after tonsillitis or pharyngitis. the primary pathogen is a gram-negative anaerobic rod, mostly fusobacterium necrophorum. previously healthy, young adults are affected mainly and the syndrome was seen more frequently in the pre-antibiotic era than it is nowadays. in the three young pat ...19938505987
outer membrane proteins of fusobacterium necrophorum biovars a, ab and b: their taxonomic relationship to f. necrophorum subspecies necrophorum and f. necrophorum subspecies funduliforme. 19938507709
pathogenicity of fusobacterium necrophorum strains from man and animals.necrobacillosis occurs in man and animals. the typical forms of the disease in animals are caused by fusobacterium necrophorum biovar a; biovar b strains are much less pathogenic. in this study the pathogenicity for mice of eight human isolates of f. necrophorum was compared with that of animal biovar a and b strains. by subcutaneous inoculation seven of the human strains differed from biovar a but resembled biovar b in (1) producing, at the most, mild local lesions that rapidly healed, and (2) ...19938519315

a comparative study of fusobacterium necrophorum strains from human and animal sources by phenotypic reactions, pyrolysis mass spectrometry and sds-page.fusobacterium necrophorum strains from human infection (21) were compared with strains from animals (17 biotype a, 2 biotype ab, 4 biotype b, 1 biotype unknown), and the type strain nctc 10575 in conventional tests reaction patterns (ctrps), sds-page and pyrolysis mass spectrometry (pms). classifications from the three approaches showed one major consensus group comprising all human strains, and another comprising animal biotype a strains. animal biotype b strains and one animal strain, designat ...19979364143
phenotypic characteristics and lipopolysaccharides of human and animal isolates of fusobacterium necrophorum.as part of a collaborative study, six culture collection isolates and 50 coded isolates of fusobacterium necrophorum were examined for the types of lipopolysaccharides (lps) they contained, and to see if this related to their reactions in a range of phenotypic tests and their susceptibility to a panel of six antimicrobial compounds. the biotype b type strain, putative biotype b isolates and human isolates were predominantly coccobacillary, had rough type lps and some of these isolates (8 of 26) ...19979364144
classification of human and animal strains of fusobacterium necrophorum by their pathogenic effects in mice.forty-six strains of fusobacterium necrophorum, 24 from animals and 22 of human origin, were examined by pathogenicity tests in mice, while the same strains were being examined in laboratories elsewhere by other methods. the pathogenicity tests consisted of (1) subcutaneous inoculation with a large dose of a pure culture, (2) subcutaneous inoculation with a small dose of f. necrophorum mixed with a large but relatively harmless dose of staphylococcus aureus, and (3) intravenous inoculation with ...19979364145
septic arthritis of the hip by fusobacterium necrophorum after tonsillectomy: a form of lemierre syndrome?lemierre syndrome used to be a complication of severe oropharyngeal infection with regional thrombophlebitis, septicaemia and septic metastatic infections caused by fusobacterium necrophorum in the pre-antibiotic era. a case of septic arthritis of the hip caused by f. necrophorum as a complication of tonsillectomy is reported in a 9-year-old boy. conclusion: lemierre syndrome, usually seen after an oropharyngeal infection, can also complicate tonsillectomy.19979392400
ribotyping to compare fusobacterium necrophorum isolates from bovine liver abscesses, ruminal walls, and ruminal contents.restriction fragment length polymorphism analysis of rrna genes was employed to genetically compare fusobacterium necrophorum subsp. necrophorum and f. necrophorum subsp. funduliforme isolates from multiple abscesses of the same liver and isolates from liver abscesses, the ruminal wall, and ruminal contents from the same animal. four livers with multiple abscesses and samples of ruminal contents, ruminal walls, and liver abscesses were collected from 11 cattle at slaughter. f. necrophorum was is ...19979406386

endopeptidase activities of selected porphyromonas spp., prevotella spp. and fusobacterium spp. of oral and non-oral origin.the ability of three porphyromonas spp., seven prevotella spp., seven fusobacterium spp. and two related bacteroides spp. (b. levii and b. macacae) to degrade an extensive range of synthetic endo-, amino- and diamino peptidase substrates linked to the fluorescent leaving group 7-amido-4-methylcoumarin (nhmec) was investigated. many more species than was previously recognized exhibited peptidase activities, albeit at lower levels than those already described for porphyromonas gingivalis. detectio ...19979460536
liver abscesses in feedlot cattle: a review.liver abscesses in slaughtered beef cattle result from aggressive grain-feeding programs. the incidence, averaging from 12 to 32% in most feedlots, is influenced by a number of dietary and management factors. liver abscesses represent a major economic liability to producers, packers, and ultimately consumers. besides liver condemnation, economic impacts include reduced feed intake, reduced weight gain, decreased feed efficiency, and decreased carcass yield. fusobacterium necrophorum, a member of ...19989464910
[septic thrombophlebitis of the internal jugular vein and lemierre syndrome].the authors report a case of lemierre's syndrome. this uncommon clinical entity is characterized by a septic internal jugular vein thrombosis with secondary metastatic abscesses and fusobacterium necrophorum septicemia, following an acute oropharyngeal infection. the diagnosis is primarily clinical and it should be suspected when a severe septicaemic illness, with pulmonary symptoms, occurs after an acute pharyngotonsillar infection. this article reviews the clinical picture, microbiology and tr ...19989553448
ammonia-hyperproducing bacteria from new zealand ruminants.pasture-grazed dairy cows, deer, and sheep were tested for the presence of ammonia-hyperproducing (hap) bacteria in roll tubes containing a medium in which tryptone and casamino acids were the sole nitrogen and energy sources. colonies able to grow on this medium represented 5.2, 1.3, and 11.6% of the total bacterial counts of dairy cows, deer, and sheep, respectively. a total of 14 morphologically distinct colonies were purified and studied further. restriction fragment length polymorphisms of ...19989572953
selecting therapy for serious infections in children: maximizing safety and efficacy.serious infections in children represent unique challenges for the treating physician. for the pediatric patient, considerations of drug toxicity are especially critical to avoid potential long-term complications of therapy. there are several advantages associated with using single, broad-spectrum, empiric antibiotic therapy, including reduced potential for drug-mediated toxicity or drug interactions and facilitation of home therapy. of the antibiotics available for monotherapy, the carbapenems ...19989635916
biochemical and biological characterizations and ribotyping of actinomyces pyogenes and actinomyces pyogenes-like organisms from liver abscesses in cattle.actinomyces pyogenes is the second most frequently encountered pathogen, next only to fusobacterium necrophorum, in liver abscesses of feedlot cattle. ninety-one isolates, presumptively identified as a. pyogenes, isolated from liver abscesses of cattle were studied. biochemical characteristics determined by the api 20 strep kit were similar to those reported previously for a. pyogenes isolated from other infections, except that 18% of isolates hydrolyzed esculin. nine isolates that resembled a. ...19989646478
postanginal septicaemia (lemmiere's disease) complicated by haemophagocytosis.we report a case of postanginal septicaemia complicated by bronchopneumonia and haemophagocytosis in a 19-year old male, presenting with severe thrombocytopenia. we believe that this is the first reported case of thrombocytopenia due to haemophagocytosis in this unusual condition.19989661952
case report: necrotic glossitis and sinusitis in a cow caused apparently by a fusobacterium necrophorum like microorganism.an unusual case of necrotic infection of the tongue and unilateral necrotic maxillar sinusitis, in a cow is reported. the prominent clinical findings were: a marked salivation, unilateral mucopurulent nasal discharge, diffuse necrotic lesions on the ventral side of the tongue and fetid breath. clinico-pathological and pathological findings and abnormalities in the haemogram were probably caused by the toxins produced by the causative organism--fusobacterium necrophorum like microorganism.19989674310
changes in bacterial populations in the colon of pigs fed different sources of dietary fibre, and the development of swine dysentery after experimental infection.swine dysentery (sd) is a disease which can be controlled by feeding a diet low in dietary fibre. the influence of source and inclusion level of dietary fibre both on bacterial populations in the colon, and on subsequent development of sd in pigs experimentally infected with serpulina hyodysenteriae was evaluated. in experiment 1, pigs were fed a low-fibre diet based on cooked rice and a animal protein supplement, or the same diet containing added insoluble (insp, fed as oaten chaff) or soluble ...19989750287
