safety and immunogenicity of a neisseria meningitidis type 2 protein vaccine in animals and humans.	two neisseria meningitidis vaccines consisting principally of outer membrane protein (lot 138i-0) or outer membrane protein plus group c polysaccharide (lot 138i-m1) were prepared from the group c type 2 strain 138i. lipopolysaccharide and lipid were removed by gel filtration in the presence of sodium deoxycholate. the vaccines were found to be nontoxic and nonpyrogenic in animals. they provided active protection in mice against mucin-enhanced killing by group b type 2 meningococci and induced g ...	1978	77885
impairment of the immune response to vaccination after acute malaria.	children with acute malaria were vaccinated with salmonella typhi and meningococcal vaccines at varying times after the onset of their illness. the immune response to both vaccines was depressed when they were given on the day of presentation at hospital. immune responsiveness to s. typhi vaccine was rapidly regained after treatment, but a month after the attack the immune response to meningococcal vaccine was still impaired.	1978	78096
degradation of the polysaccharide component of gonococcal lipopolysaccharide by gonococcal and meningococcal sonic extracts.	an extract made from the supernatant of neisseria gonorrhoeae gc2 strain 1291 degraded the gc2 polysaccharide antigen. chemical analysis of this polysaccharide indicated it contains glucose, galactose, glucosamine, galactosamine, glucosamine-6-phosphate, heptose, 2-keto-3-deoxyotonate, and ethanolamine and is the polysaccharide component of gonococcal lipopolysaccharide. degradation of the polysaccharide by sonic extracts resulted either in complete loss of antigenicity and immunogenicity or in ...	1978	78894
neisseria gonorrhoeae acquire a new principal outer-membrane protein when transformed to resistance to serum bactericidal activity.	resistance to the complement-dependent bactericidal activity of normal human serum is found in nearly all neisseria gonorrhoeae strains causing disseminated gonococcal infection. transformation of serum-sensitive gonococcal strain nrl 7189 to serum resistance using deoxyribonucleic acid from three separate disseminated-infection gonococci was accompanied by simultaneous structural and antigenic changes in the principal outer-membrane protein (pomp) of the transformants. in each of 10 separate tr ...	1978	78895
is group-specific meningococcal vaccination resulting in epidemics caused by groups of virulent meningococci?	in 1976 routine vaccination against neisseria meningitidis serogroups a and c was started in the finnish armed forces. a case of fulminant, complicated pneumonia caused by group-y meningococcus in a vaccinated recruit, prompted a study of the distribution of the meningococcal groups isolated from the recruits in the same unit. 14 (46%) of the 31 isolates from 84 recruits were group y. group-y meningococcus was rarely isolated from unvaccinated controls. these results suggest that widespread vacc ...	1978	79765

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 ...	1978	98583
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 ...	1978	98597
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 ...	1978	98600
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 ...	1978	98602
perihepatitis associated with salpingitis in adolescents.	perihepatitis, one manifestation of complicated gonorrhea, is infrequently diagnosed and reported. this study was undertaken to examine the incidence of gonococcal perihepatitis in adolescents as well as to study the effect, if any, of this condition on tests of liver function. accordingly, the records of 137 adolescents with salpingitis were evaluated. right upper quadrant tenderness or hepatic enlargement was noted in 27, while amino transferase level elevations were observed in 19 of the 59 i ...	1978	98646
gonorrhea detection in posthysterectomy patients.	a retrospective study of women examined at the venereal disease clinic after hysterectomy was made to determine which culture site was most likely to show anogenital neisseria gonorrhoeae infection when the cervix was absent. seventeen of 104 such patients were culture positive for n gonorrhoeae. rates of positivity for our culture sites were as follows: urethral, 17/17 (100%); vaginal, 7/17 (41%); and rectal, 2/17 (12%).	1978	98647
technique for transcervical intrauterine inoculation of the mouse.	suspensions of india ink or gonococci were inoculated into the murine uterus through the cervix with a simple plastic vaginal speculum and a 23 gauge blunted needle. the inoculated suspensions were distributed throughout both uterine horns, cervix, and vagina, but did not flow into the peritoneal cavity. this method avoided surgical stress as well as being simple, fast, and reproducible.	1978	98665
the bacterial pathogenesis of acute pelvic inflammatory disease.	to study the bacterial pathogenesis of acute pelvic inflammatory disease, peritoneal fluid was obtained by culdocentesis in 133 of 344 women with this disease. in 104 of the specimens bacteria were identified both in the gram-stained smear and culture. neisseria gonorrhoeae was isolated from the lower genital tract in over half of these women, and there were 3 patterns of bacterial recovery from peritoneal fluid: n gonorrhoeae alone (22%), n gonorrhoeae and other organisms (32%), and nongonococc ...	1978	98745
microbiology of the vagina in children: normal and potentially pathogenic organisms.	vaginal cultures from 100 healthy girls, 2 months to 15 years of age, were examined for the presence of normal and potentially pathogenic microorganisms. corynebacterium vaginale, yeast species, and genital mycoplasmas were isolated from vaginal cultures from 13.5 %, 28%, and 28% of the girls examined, respectively. colonization with these organisms was not associated with signs or symptoms of vaginitis. neisseria gonorrhoeae was isolated from a 4-year-old with purulent vaginitis. trichomonas va ...	1978	98750
the activity of cephalosporins on beta-lactamase-producing neisseria gonorrhoeae.	the antibacterial activity of cephaloridine, cephalothin, cephalexin, cephradine, cefazolin, cefamandole, cefuroxime and cefoxitin was determined for six beta-lactamase-producing gonococci isolated in great britain and the usa. cefuroxime was most active against small and large inocula, then cefoxitin, while cephaloridine was least active. cefamandole was more active than cefazolin and cephalothin, but only on small inocula, and these three antibiotics, with the slightly inferior cephalexin and ...	1978	98833
