| some observations on the effects produced in white mice following the injection of certain suspensions of corroding bacilli. | strictly anaerobic and facultatively anaerobic strains of "corroding bacilli" failed to produce any pathological symptoms when injected into white mice and no viable organisms could be recovered after 7 days. however, when these same strains were coupled with certain other living bacteria or certain sterile bacterial extracts, lesions developed from which corroding bacilli could be isolated even after 21 days. | 1975 | 1080 |

| the effect of nalidixic acid on microaerophilic and anaerobic bacteria. special study of clostridia. | study of the sensitivity of 141 strains of anaerobic and microaerophilic bacteria to nalidixic acid shows that few bacteria are inhibited by low concentrations (veillonella, eikenella, most of the clostridia). nalidixic acid appears to be bactericidal with respect to clostridium perfringens, and its point of attack in the dna is probably different from that of metronidazole. | 1979 | 232341 |

| selective medium for isolation of eikenella corrodens from periodontal lesions. | the addition of 5 microgram of clindamycin per ml to a modified todd-hewitt growth medium permitted the ready enumeration of eikenella corrodens from deep periodontal lesions because it allowed differential growth amongst the periodontal pocket gram-negative microaerophilic-anaerobic flora, maximized the numbers of e. corrodens in such culture, and inhibited the growth of most of the other confounding microorganisms. | 1978 | 363744 |

| role of bacterial products in periodontitis: humoral immune response to eikenella corrodens. | eikenella corrodens can induce periodontitis-like disease in gnotobiotic rats. some components of this bacterial cell elicit measurable humoral immune response during the development of the disease, but in this system endotoxin is not among the efficient immunogens. because no humoral immune response could be seen to the endotoxin of eikenella corrodens it is assumed that this endotoxin can act uncontrolled in monoinfected rats. accordingly, the lack of protective humoral immune response to path ... | 1978 | 365757 |

| modulation of human neutrophil adherence by oral bacteria. | polymorphonuclear neutrophils (pmns) comprise over 90 per cent of leukocytes in the oral cavity. although these phagocytic cells have primary defence roles in the gingiva, their stimulation by micro-organisms may also cause substantial tissue damage due to the release of lysosomal enzymes and oxygen radicals. adherence of pmns to the endothelium and their subsequent diapedesis and egress to areas of infection are considered early vital events in the inflammatory process. in this study, oral bact ... | 1992 | 1605750 |
| [polymorphonuclear leukocyte-mediated effects on human oral keratinocytes by periodontopathic bacterial extracts]. | in order to investigate the polymorphonuclear leukocyte-mediated oral keratinocyte injury, the author established a method to culture keratinocytes (scc9 and gingival keratinocytes) and subjected to the cell detachment assay by polymorphonuclear leukocytes and/or bacterial ultrasonic extracts from actinobacillus actinomycetemcomitans y4, bacteroides forsythus omz 408, fusobacterium nucleatum atcc 10953, capnocytophaga sputigena 4 and eikenella corrodens 1073. the bacterial extracts alone caused ... | 1992 | 1607829 |
| clinical and microbiological patterns of adults with periodontitis. | although current data suggest that periodontitis may actually be multiple diseases each with varying responses to therapy, little evidence exists to support this theory in adult patients. this report describes the design and initial findings of a longitudinal field trial involving the diagnosis and treatment of adult and refractory periodontitis patients in private practice. adult patients (n = 221) who met specific clinical criteria were selected from the private practices of 22 periodontists. ... | 1991 | 1663156 |

| use of monoclonal antibodies with neutralizing effects on toxic antigens from human bacterial plaque to detect specific bacteria by colony blotting. | inflammatory periodontal diseases are provoked by bacteria which adhere to teeth at the gingival margin and form plaques containing toxins detectable by their effect on mammalian cells in culture. the aim of this study was to make toxin-neutralizing monoclonal antibodies and determine whether they detect antigen in specific oral bacteria. bacterial plaque was collected from teeth and homogenized, and the fluid phase (plaque extract) was boiled or first fractionated over sephacryl s-300. hybridom ... | 1991 | 1757553 |
| fluorescence immunoassay for detecting periodontal bacterial pathogens in plaque. | a particle concentration fluorescence immunoassay has been modified into a bacterial concentration fluorescence immunoassay (bcfia) to rapidly detect periodontopathic bacteria in human plaque samples. the bcfia utilizes fluorescently tagged monoclonal antibodies (mabs) directed against the lipopolysaccharide of selected gram-negative plaque bacteria. microorganisms closely associated with periodontal disease that can be identified in plaque with the bcfia include porphyromonas gingivalis, bacter ... | 1991 | 1761686 |
