microbial differences in 2 clinically distinct types of failures of osseointegrated implants.the microflora associated with osseointegrated implants suspected of failing from infection or trauma were evaluated. of 75 patients examined, 11 demonstrated failing fixtures. 22 of 48 fixtures failed in 6 fully edentulous patients and 10 of 34 failed in 5 partially edentulous patients. the etiology of failure was attributed to infection if there was bleeding, suppuration, pain, high plaque and gingival indices and granulomatous tissue upon surgical removal. traumatic etiology was suspected in ...19911843467
anaerobic pathogenesis: collagenase production by peptostreptococcus magnus and its relationship to site of infection.fifty isolates of peptostreptococcus magnus from intraabdominal sepsis, nonpuerperal breast abscess, and diabetic foot infections were examined for collagenase activity using bovine type i collagen. collagenase production was detected in a higher percentage of strains from nonpuerperal breast and diabetic foot specimens (p less than .001). this enzyme may be responsible for p. magnus playing a more central role in the pathogenesis of nonpuerperal breast abscess and diabetic foot disease than in ...19911850443

suitability of the broth-disk elution test for evaluating susceptibility of obligate anaerobes to trimethoprim-sulfonamides.species of anaerobic bacteria isolated from clinical veterinary specimens were tested for susceptibility to trimethoprim-sulfonamides by the broth-disk elution technique. three different media were used for each organism: prereduced anaerobically sterilized (pras) brain-heart infusion broth (bhi), thioglycollate broth, and a semidefined pras medium. susceptibility results from these media were compared with those determined by interpreting the minimal inhibitory concentration obtained using an a ...19911911991
bacteriologic monitoring of periodontal diseases: cultural, enzymatic, immunologic, and nucleic acid studies.evidence supporting the bacteriologic etiology of periodontal diseases has led investigators to monitor the microbiologic species associated with each disease. the type of study performed has evolved at different levels over the years and is predominantly influenced by available technologies. as the technology has advanced, so too have attempts at monitoring specific microorganisms. the ultimate goal in most research efforts on clinical bacteriologic monitoring of the periodontal diseases has be ...19911912631
protein-kinase-c-independent activation of arachidonate release and prostaglandin e2 formation in macrophages interacting with certain bacteria.certain bacterial species, of which we selected fusobacterium nucleatum, gardnerella vaginalis, peptostreptococcus anaerobius and propionibacterium acnes, were found to induce release of arachidonic acid in a dose- and time-dependent manner in mouse macrophages. the release of arachidonic acid showed a characteristic lag period of approximately 10 min and was accompanied by selective transformation into prostaglandin e2. bacteria killed by various methods caused a similar response, indicating th ...19911915341
selection, expression, and nucleotide sequencing of the glutamate dehydrogenase gene of peptostreptococcus asaccharolyticus.the gene for the catabolic nad-linked glutamate dehydrogenase of peptostreptococcus asaccharolyticus was cloned by selection of escherichia coli for complementation of a biosynthetic defect. cloned fragments containing the gene and the p. asaccharolyticus transcription and translation signals are very highly expressed in e. coli. the nucleotide sequence of the cloned gene was determined. it codes for a polypeptide of 421 amino acids, the sequence of which is similar to those of the nadp-acceptin ...19911917850
