| identification of epitopes recognized by monoclonal antibodies sm1 and sm2 which react with all pili of neisseria gonorrhoeae but which differentiate between two structural classes of pili expressed by neisseria meningitidis and the distribution of their encoding sequences in the genomes of neisseria spp. | the pili expressed by all isolates of neisseria gonorrhoeae react with two monoclonal antibodies, sm1 and sm2. in contrast, although many isolates of neisseria meningitidis also express pili (class i) which react with antibodies sm1 and sm2, a proportion express pili (class ii) which fail to react. in order to define the epitopes recognized by these antibodies, a series of overlapping peptides corresponding to the amino acid sequence of conserved regions of gonococcal pili have been synthesized. ... | 1989 | 2483993 |

| conjugation of plasmids of neisseria gonorrhoeae to other neisseria species: potential reservoirs for the beta-lactamase plasmid. | the discovery that penicillinase production in neisseria gonorrhoeae was plasmid mediated and the spread of the beta-lactamase encoding plasmids in gonococcal isolates since 1976, raise the possibility that a nonpathogenic indigenous bacterium could serve as a reservoir for these plasmids. we initiated studies to define the ability of commensal neisseria species and branhamella catarrhalis strains, as well as strains of the pathogen neisseria meningitidis, to serve as recipients in conjugation w ... | 1984 | 6434640 |
| sequence diversity, predicted two-dimensional protein structure, and epitope mapping of neisserial opa proteins. | the sequence diversity of 45 opa outer membrane proteins from neisseria meningitidis, neisseria gonorrhoeae, neisseria sicca, and neisseria flava indicates that horizontal genetic exchange of opa alleles has been rare between these species. a two-dimensional structural model containing four surface-exposed loops was constructed based on rules derived from porin crystal structure and on conservation of sequence homology within transmembrane beta-strands. the minimal continuous epitopes recognized ... | 1998 | 9495774 |

| vasculitic purpura with antineutrophil cytoplasmic antibody-positive acute renal failure in a patient with streptococcus bovis case and neisseria subflava bacteremia and subacute endocarditis. | subacute bacterial endocarditis is frequently associated with extracardiac manifestations and renal failure. clinical variety of endocarditis manifestation is wide and has the potential to mimic vasculitis. whereas streptococcus bovis is often isolated and associated with colonic tumors, neisseriaceae are rarely found. an association of subacute bacterial endocarditis and antineutrophil cytoplasmic antibodies has been described. we report on a 62-year-old man who was admitted to our hospital wit ... | 2004 | 15356972 |
| functional diversity of three different dsba proteins from neisseria meningitidis. | the genome of neisseria meningitidis serogroup b strain mc58 contains three genes - nmb0278, nmb0294 and nmb0407 - encoding putative homologues of dsba, a periplasmic thiol disulphide oxidoreductase protein-folding catalyst of the dsb protein family. dsba assists the folding of periplasmic and membrane proteins in diverse organisms. while all three cloned genes complemented the dtt sensitivity of dsba-null escherichia coli, they showed different activities in folding specific target proteins in ... | 2004 | 15347757 |

| the significance of nongonococcal, nonmeningococcal neisseria isolates from blood cultures. | nongonococcal, nonmeningococcal neisseriae are part of the normal respiratory flora and infrequently cause disease. these organisms include neisseria lactamica, neisseria mucosa, neisseria sicca, neisseria flavescens, neisseria subflava , neisseria perflava , neisseria flava , and branhamella catarrhalis (previously classified as neisseria catarrhalis). blood cultures positive for these bacteria have been associated with serious infections, including endocarditis, septicemia, and meningitis. in ... | 1984 | 6374834 |
| expression of a high-affinity mechanism for acquisition of transferrin iron by neisseria meningitidis. | iron-starved meningococci grown at either ph 7.2 or 6.6 were capable of removing and incorporating iron from human transferrin by a saturable, cell surface mechanism that specifically recognized transferrin rather than iron. the maximum expression of the iron uptake system occurred after 4 h of iron starvation. the uptake of the iron was dependent upon a functioning electron transport chain and was sensitive to 60 degrees c and trypsin. cells grown under iron-sufficient conditions were incapable ... | 1982 | 6210635 |

| conjugal transfer of the gonococcal penicillinase plasmid. | certain gonococci, which heretofore have lacked a conjugal mating system, can sexually transfer a small plasmid (4.5 x 10)6) daltons) which carries the gene for beta-lactamase production. frequencies of conjugal transfer were similar into diverse recipients (other gonococci, neisseria flava, and escherichia coli), which suggests that gonococci may transfer the plasmid promiscuously in nature. | 1977 | 402693 |
