gonococcal color and opacity variants: virulence for chicken embryos.previous studies have noted that the prevalence of certain gonococcal colony types is influenced by the physiological state of the human host. consequently eight different gonococcal strains were passed on clear typing medium, and opaque (op) and transparent (tr) variants of heavily pilated (p++) bacteria were selected. p++op and p++tr were injected into 11-day-old chicken embryos, and the resulting mortality was determined. in every case the tr variants were more lethal to the embryos than were ...1978103830
studies on gonococcus infection. xvi. purification of neisseria gonorrhoeae immunoglobulin a1 protease.a protease which cleaves human immunoglobulin a1 (iga1) has been purified from broth cultures of neisseria gonorrhoeae. this iga1 protease is produced by pilated and nonpilated gonococci throughout their growth cycles. a combination of ammonium sulfate precipitation, column chromatography, and either isoelectric focusing or affinity chromatography was utilized to obtain an enzyme preparation that showed approximately 3,800-fold purification and exhibited two bands (65,000 and 70,000 daltons) by ...1978103829
inhibition of beta-lactamase in neisseria gonorrhoeae by sodium clavulanate.sodium clavulanate at subinhibitory concentrations affected the activity of penicillin g, ampicillin, or amoxicillin on beta-lactamase-positive strains of neisseria gonorrhoeae as demonstrated by marked reduction in the minimal inhibitory concentrations of the drugs for the organisms. the compound did not affect the activity of these penicillins on beta-lactamase-negative strains of n. gonorrhoeae. it also had no effect on the activity of cefoxitin against either beta-lactamase-negative or -posi ...1978103496
effects of thiamphenicol and chloramphenicol in inhibiting neisseria gonorrhoeae isolates.thiamphenicol was compared with penicillin, tetracycline, and chloramphenicol for its ability to inhibit 530 isolates of neisseria gonorrhoeae, including 13 penicillinase-producing isolates. thiamphenicol proved to be as active as chloramphenicol in inhibiting all of the isolates.1978103495
laboratory identification of pathogenic neisseria with special regard to atypical strains: an evaluation of sugar degradation, immunofluorescence and co-agglutination tests.sugar degradation tests (sdt) were compared with immunofluorescence (ifl) and co-agglutination (coa) tests for the diagnosis of neisseria gonorrhoeae (gc) and neisseria meningitidis (mc). somewhat more than 5% of the gc strains and 8% of the mc strains were misinterpreted by sdt. on most occasions the disagreement between sdt and serological tests was due to the inability of the mc strains (less so for gc strains) to degrade sugars correctly. because of this, three out of 15 strains (20%) from p ...1978103365

serum bactericidal action and activation of the classic and alternate complement pathways by neisseria gonorrhoeae.in order to more fully understand the host defense mechanisms against gonococcal infections, we decided to define the role of the classic and alternate complement pathways in gonococcal ba. sera and infecting isolates were collected from several patients with genital and disseminated gonococcal infections. sera from two never-infected subjects and a hypogammaglobulinemic patient were also collected. sera from patients with genital gonorrhea and never-infected controls demonstrated marked ba for ...197898602
phenotypic and epidemiologic correlates of auxotype in neisseria gonorrhoeae.previous studies from seattle, wash., suggested that strains of neisseria gonorrhoeae which require arginine, hypoxanthine, and uracil (arg-hyx-ura- auxotype) are unifomly highly susceptible to penicillin g, are relatively resistant to complement-dependent killing by heated, pooled human serum, and are associated with disseminated gonococcal infection. for further study of the epidemiology of these strains and for analysis of the susceptibility to penicillin, serum sensitivity, and the nutrition ...197898600
quantitative determination of the serum antibody response to the capsular polysaccharide of bacteroides fragilis subspecies fragilis in women with pelvic inflammatory disease.the antibody response to the capsular polysaccharide of bacteroides fragilis subspecies fragilis in women with acute pelvic inflammatory disease was quantitated using a sensitive radioactive antigen-binding assay. antibody detected by this technique correlated highly with antibody measured by quantitative precipitin analysis (r = 0.99). paired acute- and convalescent-phase sera obtained from women from whom b. fragilis subspecies fragilis was isolated by culdocentesis showed significantly greate ...197898597
bacteria induce lymphokine synthesis polyclonally in human b lymphocytes.we have studied the ability of various bacteria to stimulate human lymphocytes to produce leukocyte migration inhibitory factor (lif). mononuclear cells from adult and cord blood as well as purified t and b lymphocytes were stimulated with killed bacteria. the culture supernatants were tested for the presence of lif by the agarose migration method. all nine bacterial strains tested activated unseparated mononuclear cells and b lymphocytes but not t cells to produce lif. lif was also present in c ...197898583
sensitivity of gonococcus strains isolated in rotterdam to epicillin, ampicillin, penicillin and tetracycline.quantitative determinations of the sensitivity to epicillin, ampicillin, penicillin and tetracycline were carried out for 67 gonococcus strains isolated from 67 males with urogenital gonorrhoea, and 38 strains isolated from 38 females with urogenital/rectal gonorrhoea. the results of the sensitivity determinations for ampicillin, penicillin and tetracycline were compared with the findings of a previous investigation. it was found that the gonococcus strains isolated from males had become slightl ...197898362

effects of various divalent cations on the survival of neisseria gonorrhoeae in liquid media.the effect of various concentrations of divalent cations on survival of gonococci in liquid medium was studied. the growth of neisseria gonorrhoeae was inhibited by manganous chloride in concentrations above 1 x 10(-5)mol/l while the growth of control organisms such as neisseria meningitidis and escherichia coli was not inhibited by the same salt even at 1 x 10(-2)mol/l. copper sulphate, cobaltous nitrate, nickel chloride, and zinc sulphate also had deleterious effects on gonococci. magnesium ch ...197898204
genital inoculation of male macaca fascicularis with neisseria gonorrhoeae and ureaplasma urealyticum.inoculation of the urethra, conjunctiva, pharynx, and anal canal of six male crab-eating macaques (macaca fascicularis) with urethral exudate from male patients with urethral gonorrhoea or with laboratory gonococcal strains was unsuccessful in establishing infection or producing increased polymorphonuclear leucocytes on gram stain. intraurethral inoculation with laboratory strains of ureaplasma urealyticum resulted in transiently positive urethral cultures for u. urealyticum and was associated i ...197898203
[study of molecular heterogeneity and chemical nature of polymeric components of the meningococcus cell wall].the high-molecular fraction of substances of the cell wall of meningococci, groups a and b, isolated in free volume in gel filtration through sepharose 4b and containing both group and intergroup antigens proved to be consisting of 2 subfractions in gel-filtration through bio-gel a-150m. molecular weight of the first was within the range of 100--150 million dalton, and of the second--of 3 to 100 million dalton. in dissociation in sodium deoxycholate the high molecular fraction complex compound o ...197897883
