blastogenic response of human lymphocytes to antigens of rothia dentocariosa.	peripheral blood lymphocytes were isolated from 20 individuals with varying degrees of periodontal health and classified as either normal, having acute gingivitis (gv), or chronic periodontitis (pd). crude cell wall and cytoplasmic antigens were derived from rothia dentocariosa (rd), were applied to lymphocyte microcultures, and subjected to radioactive thymidine; the resulting lymphocyte blastogenesis (lb) was surveyed with a scintillation counter. all three groups displayed statistically simil ...	1982	6953091
a numerical taxonomic study of members of the actinomycetaceae and related taxa.	two hundred and twenty-two representatives of the actinomycetaceae and related taxa, including reference cultures, received strains and fresh isolates, were tested using 124 unit characters. the data were examined using numerical taxonomic techniques with various coefficients and average linkage clustering; the variation in composition of the clusters obtained from the different coefficients was slight. most species included in the study formed discrete phena, which exhibited good differential c ...	1981	7343641
oral microflora of the ferret at the gingival sulcus and mucosa membrane in relation to ligature-induced periodontitis.	the aim of this study was to describe, in the domestic ferret, the composition of the normal gingival sulcus and the near related mucosa microflora and the shift in the composition during an acute periodontal breakdown induced by the placement of ligatures. five animals were used. at the start of the experiment (day 0) and before the placement of the ligatures, 2 microbiological samples were obtained from the gingival sulcus and the related mucosa at the mid-buccal surface of the right upper p4. ...	1994	7478754
study of stomatococcus mucilaginosus isolated in a hospital ward using phenotypic characterization.	thirty-one isolates of stomatococcus mucilaginosus were cultured from the blood (n = 6), throat (n = 23) and sputum (n = 2) of 18 hospitalized patients, 13 of whom were neutropaneic and five of whom were non-neutropaneic. antibiotic susceptibility testing, performed by means of a broth microdilution method, showed that the minimal inhibitory concentrations (mics) of ciprofloxacin were > or = 4 mg/l for the isolates collected from neutropaenic patients. all these patients received ciprofloxacin a ...	1995	7614959
imaging of choroid plexus infection by stomatococcus mucilaginosus in neutropenic patients.	we report two neutropenic patients with stomatococcus mucilaginosus meningitis and choroid plexus involvement on neuroimaging studies. ct and mr showed abnormal enlargement of the choroid plexus in one lateral ventricle and intense enhancement. in one patient there was edema in the periventricular white matter adjacent to the involved choroid plexus; in both patients there was enhancement of the ependyma.	1995	7677035
antimicrobial susceptibilities of stomatococcus mucilaginosus and of micrococcus spp.	the in vitro susceptibilities of 63 isolates of stomatococcus mucilaginosus and of 188 isolates of micrococcus spp. to 18 antimicrobial agents were determined by the agar dilution method. many beta-lactams, imipenem, rifampin, and the glycopeptides were shown to be active in vitro against stomatococcus and micrococcus isolates, whereas the activities of antibiotics such as some aminoglycosides, erythromycin, and fosfomycin against an important number of these microorganisms are limited.	1995	7695321
four-year prospective study of staph-ident system and conventional method for reference identification of staphylococcus, stomatococcus, and micrococcus spp..	a 4-year prospective study compared the accuracy of the staph-ident system (biomérieux vitek, inc., hazelwood, mo.) with that of the reference procedure of the centers for disease control and prevention for the identification of staphylococcus species, stomatococcus mucilaginosus, and micrococcus species. the study compared the results from 1,106 cultures (500 eye cultures, 217 strains submitted for reference identification, and 389 known stock strains) representing 21 species of the family micr ...	1995	7699074
stomatococcus mucilaginosus produces a mannose-containing lipoglycan rather than lipoteichoic acid.	five strains of stomatococcus mucilaginosus were investigated to determine whether the organism produces a lipoteichoic acid or a lipoglycan. crude phenol extracts were purified by hydrophobic interaction chromatography and shown to contain lipoglycan. the major carbohydrate component present was mannose, indicating that the macroamphiphile is a lipomannan. the fatty acid composition of the lipoglycan was similar to that of stomatococcal whole cells. these data provide additional chemotaxonomic ...	1995	7710324
association of stomatococcus mucilaginosus with cholangitis.	the first case of cholangitis in which stomatococcus mucilaginosus was cultured from bile is reported. a 64-year-old male became icteric and was shown to have gallstones in the gallbladder and a common bile duct stone which was removed endoscopically. as the patient remained icteric for a month thereafter the gallbladder with stones was removed. no common bile duct stone was shown by cholangiography perioperatively. the liver biopsy revealed cholangitis and stomatococcus mucilaginosus was grown ...	1994	7805692
