| evidence for plasticity and structural mimicry at the immunoglobulin light chain-protein l interface. | the multidomain bacterial surface protein l (ppl) is a virulence factor expressed by only 10% of peptostreptococcus magnus strains, and its expression is correlated with bacterial vaginosis. the molecular basis for its ability to recognize 60% of mammalian immunoglobulin light chain variable regions (v(l)) has been described recently by x-ray crystallography, which suggested the presence of two v(l) binding sites on each protein l domain (graille, m., stura, e. a., housden, n. g., beckingham, j. ... | 2002 | 12221088 |
| bacteriocin-like activity of butyrivibrio fibrisolvens jl5 and its effect on other ruminal bacteria and ammonia production. | when ruminal bacteria from a cow fed hay were serially diluted into an anaerobic medium that had only peptides and amino acids as energy sources, little growth or ammonia production was detected at dilutions greater than 10(-6). the 10(-8) and 10(-9) dilutions contained bacteria that fermented carbohydrates, and some of these bacteria inhibited clostridium sticklandii sr, an obligate amino acid-fermenting bacterium. phylogenetic analysis indicated that the most active isolate (jl5) was closely r ... | 2002 | 11872448 |
| periodontal bacteria in rabbit mandibular and maxillary abscesses. | despite the high incidence of odontogenic abscesses in pet rabbits, published data on the bacteriology of these infections are lacking, and clinical cultures are often ambiguous, making antibiotic choices difficult. in order to define the bacteriology of these infections, 12 rabbit mandibular and maxillary abscesses were cultured aerobically and anaerobically. all specimens yielded pathogenic bacteria, including fusobacterium nucleatum, prevotella heparinolytica, prevotella spp., peptostreptococ ... | 2002 | 11880435 |
| differences in backbone dynamics of two homologous bacterial albumin-binding modules: implications for binding specificity and bacterial adaptation. | proteins g and pab are bacterial albumin-binding proteins expressed at the surface of group c and g streptococci and peptostreptococcus magnus, respectively. repeated albumin-binding domains, known as ga modules, are found in both proteins. the third ga module of protein g from the group g streptococcal strain g148 (g148-ga3) and the second ga module of protein pab from p.magnus strain alb8 (alb8-ga) exhibit 59% sequence identity and both fold to form three-helix bundle structures that are very ... | 2002 | 11884146 |
| protein l mutants for the crystallization of antibody fragments. | in many cases, antibody and their complexes can be crystallized and their structure determined without major difficulties. the remaining problematic cases may be approached through techniques such as of combinatorial complex crystallization which uses immunoglobulin binding proteins (ibp). the range of lattices that can be made using this method can be expanded by engineering mutants of ibp domains. we have designed peptostreptococcus magnus protein l (ppl) mutants with altered immunoglobulin li ... | 2002 | 12351898 |

| initial effect of controlled release chlorhexidine on subgingival microorganisms. | little or no data exist on the ability of subgingival application of periochip (2.5 mg chlorhexidine gluconate in a biodegradable chip; astra pharmaceuticals, westborough, ma, usa) to suppress periodontopathic microorganisms. the present study compared the subgingival microbiota of periodontitis sites receiving the chlorhexidine chip plus scaling and root planing (sc/rp) or sc/rp alone. | 2002 | 12366861 |
| sequence variations within protein families are linearly related to structural variations. | it is commonly believed that similarities between the sequences of two proteins infer similarities between their structures. sequence alignments reliably recognize pairs of protein of similar structures provided that the percentage sequence identity between their two sequences is sufficiently high. this distinction, however, is statistically less reliable when the percentage sequence identity is lower than 30% and little is known then about the detailed relationship between the two measures of s ... | 2002 | 12381308 |

| heterogeneity within the gram-positive anaerobic cocci demonstrated by analysis of 16s-23s intergenic ribosomal rna polymorphisms. | peptostreptococci are gram-positive, strictly anaerobic bacteria which, although regarded as members of the commensal human microflora, are also frequently isolated from sites of clinical infection. the study of this diverse group of opportunist pathogens has been hindered by an inadequate taxonomy and the lack of a valid identification scheme. recent re-classification of the peptostreptococcus family into five distinct genus groups has helped to clarify the situation. however, this has been on ... | 2002 | 12448679 |
| bacteriology of acute and chronic sphenoid sinusitis. | aspirates of 16 acutely infected and 7 chronically infected sphenoid sinuses were processed for aerobic and anaerobic bacteria. a total of 29 isolates were recovered from the 16 cases of acute sphenoid sinusitis (1.8 per specimen): 22 aerobic and facultative (1.4 per specimen), and 7 anaerobic (0.4 per specimen). aerobic and facultative organisms alone were recovered in 10 specimens (62%), anaerobes alone were isolated in 3 (19%), and mixed aerobic and anaerobic bacteria were recovered in 3 (19% ... | 2002 | 12450174 |

| development of a pcr assay specific for peptostreptococcus anaerobius. | peptostreptococcus anaerobius is a gram-positive anaerobic coccus that is widely distributed in the normal human flora. the organism has also been implicated as a causative agent of several systemic infections, including endocarditis and infections of the genitourinary and gastrointestinal tracts. its role in oral disease is less well defined, although it has been implicated in periodontal disease, gingivitis and root canal infections. identification of p. anaerobius in clinical samples is curre ... | 2002 | 12466408 |
| porphyromonas gingivalis, bacteroides forsythus and other putative periodontal pathogens in subjects with and without periodontal destruction. | bacteria play an essential role in the pathogenesis of destructive periodontal disease. it has been suggested that not all bacteria associated with periodontitis may be normal inhabitants of a periodontally healthy dentition. in particular, porphyromonas gingivalis and actinobacillus actinomycetemcomitans have been isolated infrequently from subjects without periodontitis. the aim of the present study was to compare prevalence and proportions of a number of periodontal bacteria in periodontitis ... | 2002 | 12472995 |
