conclusions nucleic acid amplification tests (naats) are very appropriate in detection of infected individuals. detection techniques such as naats are independent of bacterial viability, and have a potential to limit false negative samples, therefore, in our country, the application of different laboratory diagnosis methods including naats with culture as gold standard for determination antimic...
Computational analysis, design and expression of hybrid antibody in Single Chain Fragment Variable (scFv) form for identifying surface antigen factor H binding protein (fHbp) Neisseria meningitidis
objective: sexually transmitted infections (stis) remain a public health problem of major significance in most parts of the world. this study aimed to detect the most prevalent pathogens in patients with signs and symptoms of sti referring to a group of university clinics in tehran. materials and methods: in this cross-sectional study using randomized cluster sampling, 507 consecutive male and ...
Wheat-germ agglutination (WGA) was used to identify 168 strains of Neisseria gonorrhoeae and 105 strains of other Neisseria species in a routine laboratory. About one-third of the meningococci reacted with the lectin and titres with some organisms varied on repeat testing. The technique is regarded as unreliable for the identification of Neisseria species.
Molecular analyses of mip and ompA genes were performed on 20 Neisseria gonorrhoeae isolates. The genes were present with a high degree of conservation in all strains. Sera from patients with urethritis or disseminated gonococcal infections were able to recognize the purified Neisseria gonorrhoeae macrophage infectivity potentiator (Ng-MIP) and Neisseria gonorrhoeae outer membrane protein A (Ng...
The varied pressures required for disruption of Neisseria gonorrhoeae and other species of Neisseria when the Sorvall-Ribi refrigerated cell fractionator is used in the preparation of cell walls and cellular protoplasm are reported. Optimal disruption pressure for the gonococcus was considerably less than that required for other members of the genus Neisseria. Pressures varied from 8,000 psi fo...

Gonorrhea may become untreatable due to the spread of resistant or multidrug-resistant strains. Cefixime-resistant gonococci belonging to sequence type 1407 have been described worldwide. We report the genome sequence of Neisseria gonorrhoeae strain G2891, a multidrug-resistant isolate of sequence type 1407, collected in Italy in 2013.
Commensal bacteria comprise a large part of the microbial world, playing important roles in human development, health and disease. However, little is known about the genomic content of commensals or how related they are to their pathogenic counterparts. The genus Neisseria, containing both commensal and pathogenic species, provides an excellent opportunity to study these issues. We undertook a ...
An 8-year-old boy developed proctitis. Rectal swabs yielded a Neisseria sp. that was repeatedly identified by API (Analytab Products, Plainview, N.Y.), Minitek (BBL Microbiology Systems, Cockeysville, Md.), and Bactec (Johnston Laboratories, Towson, Md.) methods as Neisseria gonorrhoeae. Subsequent testing in a reference laboratory yielded an identification of Neisseria cinerea. It is suggested...
