down-modulation of the antigen receptor by a superantigen for human b cells.b cell superantigens (sags) have been implicated in human diseases by demonstrating non-clonotypic expansion of b cells bearing certain immunoglobulin variable region genes. one possibility is that, during infection with microorganisms secreting sags, these potent molecules might modulate bcr expression. to test this hypothesis, we investigated the potential effects of a sag, protein l from peptostreptococcus magnus, on antigen b cell receptor (bcr) surface expression in vitro. using fluorescenc ...200415081532

changes in oral microbial profiles after periodontal treatment as determined by molecular analysis of 16s rrna genes.terminal rflp (t-rflp) analysis was used to investigate changes in the oral microbiota in saliva and subgingival plaque samples from one patient with aggressive periodontitis (subject a) and two patients with chronic periodontitis (subjects b and c) before and 3 months after periodontal treatment. substantial changes in the t-rflp patterns of subgingival plaque samples of subjects b and c were noted after 3 months of improved oral hygiene and full-mouth supra- and subgingival scaling and root pl ...200415150339
apical periodontitis development and bacterial response to endodontic treatment. experimental root canal infections in monkeys with selected bacterial six monkeys, 160 root canals were inoculated with a combination of four bacterial strains belonging to species streptococcus milleri, peptostreptococcus anaerobius, prevotella oralis, and fusobacterium nucleatum. in two other monkeys, 24 root canals were inoculated with a five-strain combination consisting of these strains and a strain of enterococcus faecalis. all strains were previously isolated from an infected monkey root canal. after 8-12 months, survival of the strains was recorded bact ...200415154917
in vitro activities of the new semisynthetic glycopeptide telavancin (td-6424), vancomycin, daptomycin, linezolid, and four comparator agents against anaerobic gram-positive species and corynebacterium spp.telavancin is a new semisynthetic glycopeptide anti-infective with multiple mechanisms of action, including inhibition of bacterial membrane phospholipid synthesis and inhibition of bacterial cell wall synthesis. we determined the in vitro activities of telavancin, vancomycin, daptomycin, linezolid, quinupristin-dalfopristin, imipenem, piperacillin-tazobactam, and ampicillin against 268 clinical isolates of anaerobic gram-positive organisms and 31 corynebacterium strains using agar dilution meth ...200415155214
specific in vivo deletion of b-cell subpopulations expressing human immunoglobulins by the b-cell superantigen protein l.some pathogens have evolved to produce proteins, called b-cell superantigens, that can interact with human immunoglobulin variable regions, independently of the combining site, and activate b lymphocytes that express the target immunoglobulins. however, the in vivo consequences of these interactions on human b-cell numbers and function are largely unknown. using transgenic mice expressing fully human immunoglobulins, we studied the consequences of in vivo exposure of protein l of peptostreptococ ...200415155659

[a case of infected emphysematous bulla successfully treated with percutaneous thoracic drainage].we present a case of infected emphysematous bulla successfully treated by percutaneous drainage. a 39-year-old man was admitted to our hospital because of fever and right lateral chest pain. a chest radiograph and ct revealed a cystic lesion with an air fluid level in the upper lobe of the right lung. the infected emphysematous bulla was not improved by the administration of antibiotics. on day 6 of hospitalization, a drainage tube (aspiration kit: 6 fr) was inserted percutaneously into the bull ...200415228143
crystal structure and biological implications of a bacterial albumin binding module in complex with human serum albumin.many bactericide species express surface proteins that interact with human serum albumin (hsa). protein pab from the anaerobic bacterium finegoldia magna (formerly peptostreptococcus magnus) represents one of these proteins. protein pab contains a domain of 53 amino acid residues known as the ga module. ga homologs are also found in protein g of group c and g streptococci. here we report the crystal structure of hsa in complex with the ga module of protein pab. the model of the complex was refin ...200415269208
[bacterial infections in chronic otitis media--usefulness of molecular diagnostics based on pcr method].infections in chronic otitis media (com) are common, and identification of their pathogen is difficult, what is proven by high rate of negative results of bacteriological examinations. this fact may be explained by two factors: it is difficult to obtain a reliable material for culture and classic methods of bacteriological cultures may be of low sensitivity. amplification of bacterial dna in pcr is an examination, that leads to a higher effectiveness and sensitivity of bacteriological tests. the ...200415311593
