[results of treatment of deep neck abscesses and phlegmons].neck, as a structure very closely connected with oral cavity and pharynx, with great number of lymph nodes, (about 2, 3 of all are in the neck), is sometimes a localization of purulent inflammatory process but its incidence is not so high as the incidence of inflammations of surrounding organs and tissue. deep neck abscesses are localized under the upper fascial layer. they have a serious clinical picture which could be further complicated if inflammation spreads on vessels or neck organs. if th ...199910624393
robustness of protein folding kinetics to surface hydrophobic substitutions.we use both combinatorial and site-directed mutagenesis to explore the consequences of surface hydrophobic substitutions for the folding of two small single domain proteins, the src sh3 domain, and the igg binding domain of peptostreptococcal protein l. we find that in almost every case, destabilizing surface hydrophobic substitutions have much larger effects on the rate of unfolding than on the rate of folding, suggesting that nonnative hydrophobic interactions do not significantly interfere wi ...199910631990
quinupristin/dalfopristin: a review of its use in the management of serious gram-positive infections.quinupristin/dalfopristin is the first parenteral streptogramin antibacterial agent, and is a 30:70 (w/w) ratio of 2 semisynthetic pristinamycin derivatives. the combination has inhibitory activity against a broad range of gram-positive bacteria including methicillin-resistant staphylococci, vancomycin-resistant enterococcus faecium (vref), drug-resistant streptococcus pneumoniae, other streptococci, clostridium perfringens and peptostreptococcus spp. the combination also has good activity again ...199910651391
cloning of fiba, encoding an immunogenic subunit of the fibril-like surface structure of peptostreptococcus micros.although we are currently unaware of its biological function, the fibril-like surface structure is a prominent characteristic of the rough (rg) genotype of the gram-positive periodontal pathogen peptostreptococcus micros. the smooth (sm) type of this species as well as the smooth variant of the rg type (rgsm) lack these structures on their surface. a fibril-specific serum, as determined by immunogold electron microscopy, was obtained through adsorption of a rabbit anti-rg type serum with excess ...199910198013
coaggregation of candida dubliniensis with fusobacterium nucleatum.the binding of microorganisms to each other and oral surfaces contributes to the progression of microbial infections in the oral cavity. candida dubliniensis, a newly characterized species, has been identified in human immunodeficiency virus-seropositive patients and other immunocompromised individuals. c. dubliniensis phenotypically resembles candida albicans in many respects yet can be identified and differentiated as a unique candida species by phenotypic and genetic profiles. the purpose of ...199910203506
adherence of peptostreptococcus micros morphotypes to epithelial cells in vitro.peptostreptococcus micros, which is associated with oral and non-oral mixed anaerobic infections, occurs in three colony morphotypes, the smooth type, the rough type and the smooth variant of the rough type. these types differ in surface structures; the rough type expresses large fibrillar surface appendages, which are absent on the surface of both the smooth and the smooth variant of the rough type. to determine the role of these surface structures in adherence we characterized the adherence of ...199910204480
coagulase-negative staphylococci are the most common bacteria found in cultures from the deep portions of hidradenitis suppurativa lesions, as obtained by carbon dioxide laser surgery.the significance of bacterial findings in hidradenitis suppurativa (hs) is controversial. interpretation of the results of bacteriological examinations from the surface of hs lesions is obscured by the possible contamination of resident skin bacteria. bacteriological analysis of aspirates from deeper parts of hs is liable to show low sensitivity. we used a carbon dioxide (co2) laser method to evaporate the diseased tissue level by level from the surface downwards, allowing concurrent sampling of ...199910215774
metronidazole susceptibility testing of anaerobic bacteria associated with periodontal disease.the aim of the present investigation was to determine the susceptibility of prevotella intermedia, porphyromonas gingivalis, fusobacterium and peptostreptococcus micros to metronidazole in vitro. two methods were applied on each isolated strain: agar dilution and epsilometer etest. a total of fifty three wild test strains (13 p.intermedia, 14 p. gingivalis, 14 f.spp and 12 p.micros) were isolated from patients with periodontitis. the etest appears to be a simple, rapid and reliable method for th ...199910223399
