the epidemiology of infections due to neisseria meningitidis and neisseria lactamica in a northern nigerian community.	the epidemiology of infection due to neisseria meningitidis and neisseria lactamica was studied in a northern nigerian community. a low meningococcal carriage rate was observed throughout the two-year survey. initially, most meningococci isolated from nasopharyngeal carriers belonged to serogroup c or to serogroup y. following an outbreak of group a meningococcal disease, more group a meningococcal carriers were detected. antibody studies indicated that infection with group a meningococci had be ...	1982	7130749
[frequency and characterization of "neisseria lactamica" among the population of milan italy (author's transl)].	in 1979, 4,941 asymptomatic subjects, ranging from children to adolescents and working-age adults living in the milan area, were examined for the presence of neisseriae in rhinopharyngeal exudate. 382 carriers of neisseriae were identified (7.7%); of these, 265 (5.3%) presented neisseria meningitidis and 117 (2.4%) neisseria lactamica. carriers of neisseria lactamica were found more frequently among children and adolescents than among adults of working age. the strains of neisseria lactamica iso ...	1981	6803684
isolation of neisseria lactamica from the female genital tract. a case report.	neisseria lactamica was isolated from the genital tract of a young patient with a persistent vaginal discharge. although infection with n lactamica occurs very rarely, the importance of complete biochemical identification of neisseriae is emphasised in view of the serious social and medicolegal consequences which could result from a misdiagnosis of gonorrhoea.	1980	7427704
inhibition of neisseria gonorrhoeae by normal human saliva.	saliva was found to be a powerful and specific inhibitor of neisseria gonorrhoeae. although 28 other species of bacteria were tested, including neisseria meningitidis, neisseria pharyngis var flava, neisseria lactamica, and neisseria catarrhalis, we failed to find any others sensitive to saliva under similar conditions. the physical properties of the inhibitory substance indicated that it might be salivary alpha-amylase. to test this hypothesis alpha-amylase was extracted from saliva and was sho ...	1979	106919
hen fluorescein-labeled gonococcal lipopolysaccharide antibody in the delayed fluorescent antibody technique for the confirmation of neisseria gonorrhoeae.	a fluorescent antibody reagent (termed anti-lps conjugate) was prepared from sera obtained from hens immunized with gonococcal r-type lipopolysaccharide. the reagent was absorbed with formalin-treated cells of neisseria meningitidis. the anti-lps conjugate gave uniform brilliant staining of neisseria gonorrhoeae with little background fluorescence, thus making interpretation and reading of fluorescence simple. the conjugate did not significantly stain cultures of n. meningitidis, neisseria lacta ...	1979	110824
comparison of three methods for identification of pathogenic neisseria species.	a radiometric procedure was compared with the minitek and cystine trypticase agar sugar degradation methods for identification of 113 neisseria species (58 neisseria meningitidis, 51 neisseria gonorrhoeae, 2 neisseria lactamica, 2 neisseria sicca). identification of meningococci and gonococci was confirmed by agglutination and fluorescent antibody techniques, respectively. the minitek method identified 97% of meningococci, 92% of gonococci, and 100% of other neisseria after 4 h of incubation. th ...	1979	383747

carriage of neisseria meningitidis and neisseria lactamica in infants and children.	asymptomatic carriage of neisseria meningitidis and neisseria lactamica was studied in a total of 2,969 healthy infants and children in danbury, conn., between october 1971 and june 1975. the prevalence of n. meningitidis averaged 0.71% during the first four years of life and increased to 5.4% by 14--17 years. rates of carriage of n. lactamica increased from 3.8% in three-month-old infants to a peak of 21.0% at 18 months and then declined to 1.8% by 14--17 years of age. of the children who acqui ...	1978	415097
the lipopolysaccharide (r type) as a common antigen of neisseria gonorrhoeae. ii. use of hen antiserum to gonococcal lipopolysaccharide in a rapid slide test for the identification of n. gonorrhoeae from primary isolates and secondary cultures.	an antiserum has been prepared in hens to r-type gonococcal lipopolysaccharide (lps) and used in a simple slide-agglutination test for the identification of neisseria gonorrhoeae. anti-lps serum agglutinated gonococcal cells representative of the four colony types of n. gonorrhoeae. absorption of the antiserum with lps removed the agglutinating activity. secondary cultures (1120) were tested without observation of the colony type and all were agglutinated. no agglutination occurred with strains ...	1978	417781

neisseria meningitidis in the anal canal of homosexual men.	cultures were obtained from the oropharynx, urethra, and anal canal of 157 homosexual men. neisseria gonorrhoeae was identified in 30 men (19.1%), neisseria meningitidis in 32 men (20.4%), and neisseria lactamicus and branhamella catarrhalis in one man each. n. gonorrhoeae was isolated from the anal canal of three men (1.9%), and n. meninititidis was identified in the anal canal of seven men (4.5%). these findings suggest that confirmatory tests are indicated for homosexual males with rectal iso ...	1977	411836
neisseria lactamica meningitis.	neisseria lactamica was recovered from the blood and cerebrospinal fluid of a 7-month-old girl with acute purulent meningitis. the isolate was identified initially as n meningitidis. however, additional biochemical testing at the center for disease control showed that the organism fermented lactose and produced beta-d-galactosidase, thereby confirming its identity as n lactamica.	1976	814807
[experience with neisseria lactamica (author's transl)].	the authors have performed a detailed study of the presence of a new microbial species, neisseria lactamica which even recently had still been classified among the nontypable neisseria meningitidis strains. an examination of the spread of neisseria strains among the healthy population of this country revealed 1.6% to be carriers of neisseria lactamica as compared with 4.7% being carriers of neisseria meningitidis. from the material examined, the highest number of neisseria lactamica carriers was ...	1976	827879
septicemia due to neisseria lactamica.	neisseria lactamica was isolated from the blood of a pediatric patient who had signs of septicemia and otitis media. organisms morphologically resembling neisseria, as well as gram-positive cocci, were seen on a gram stain of fluid from the middle ear. it is hypothesized that the n. lactamica septicemia was secondary to infection of the middle ear by this organism.	1976	972188

isolation of neisseria lactamicus from the nasopharynx.	during 1971 and 1972, 71 cultures of neisseriae that attacked lactose were received by this laboratory. all strains except one from an eye swab were from the nasopharynx of healthy subjects. nineteen similar strains from the nasopharynx were isolated in this laboratory. the characteristics of these strains were compared with those of neisseria meningitidis, neisseria pharyngis, neisseria catarrhalis, and neisseria lactamicus. the 90 strains under investigation closely resembled neisseria meningi ...	1973	4198110

partial reassociation between the deoxyribonucleic acids of neisseria lactamicus and neisseria meningitidis.	the similarity in polynucleotide sequence of seven strains of neisseria lactamicus to n. meningitidis and to each other was investigated. the per cent reassociation between single-stranded n. lactamicus deoxyribonucleic acid (dna), immobilized on membrane filters, with labeled single-stranded dna fragments derived from strain sd-6 (group c) of n. meningitidis varied from 75 to 56. with strain atcc 23972 of n. lactamicus furnishing the labeled dna fragments, reassociation was 72% with n. meningit ...	1971	16557965
neisseria lactamicus sp. n., a lactose-fermenting species resembling neisseria meningitidis.	the biochemical and serological characteristics of lactose-utilizing strains of neisseria were determined. these organisms were found in the nasopharynx of man and grew well on thayer-martin selective medium. they were compared with n. meningitidis to ascertain whether they were variants of this species. differences between the lactose-using strains and the recognized species of neisseria were considered significant enough to warrant designation of a new species, neisseria lactamicus. this group ...	1969	4975454
