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...

A group of five tests utilizing wheat germ and soybean lectins and chromogenic substrates (orthonitrophenyl-beta-D-galactopyranoside, gamma-glutamyl-beta-naphthylamide, and prolyl-beta-naphthylamide derivatives) was used as a rapid (30-min) method for the identification of Neisseria gonorrhoeae. The rapid method agreed with Minitek test results for all 126 N. gonorrhoeae isolates and all 39 non...

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...

A carbohydrate fermentation plate medium is described for rapid and reliable confirmation of Neisseria gonorrhoeae, N. meningitidis, and other Neisseria species. The medium is based on a modification of NYC (U.S. Patent 3,846,241) medium, originally designed for the isolation of pathogenic Neisseria (3). A total of 715 clinical isolates were tested for their carbohydrate fermentation reactions ...

During a 12-month period 285 isolates of Neisseria species, other than Neisseria gonorrhoeae, were cultured from patients attending the Department of Venereology, Royal Infirmary, Edinburgh. There were eight patients in whom genitourinary or rectal isolates of Neisseria meningitidis or Neisseria catarrhalis were found. Differences between data from our series and from previous reports are discu...

Bakteri endofit memiliki karakteristik berada dalam jaringan tumbuhan (akar, batang, daun, dan bunga) tanpa menyebabkan gangguan pada tumbuhan. Tujuan penelitian ini untuk mengetahui bakteri yang diisolasi dari akar napas (Pneumatofor) Avicennia marina. Pengambilan sampel dilakukan di Mempawah Mangrove Park (MMP), Desa Pasir, Kabupaten Mempawah. Isolasi dengan metode pengenceran tuang (pour pla...
