We evaluated a DNA biotinylated probe for the rapid identification of Neisseria gonorrhoeae in culture (Ortho Diagnostics System, Raritan, NJ). Twenty-one strains of N. gonorrhoeae, including type strain, 57 strains of other Neisseria species, and 104 strains of other genera were studied. The probe was highly sensitive (100%) and specific (96%). All N. gonorrhoeae strains gave strong signals, and only two cross-reaction were observed with N. lactamica, which has a close genetic relationship to N. gonorrhoeae. Our results indicate that specific recombinant DNA probe should offer a reliable and rapid method for routine diagnosis of Neisseria gonorrhoeae.

UI MeSH Term Description Entries
D009344 Neisseria gonorrhoeae A species of gram-negative, aerobic bacteria primarily found in purulent venereal discharges. It is the causative agent of GONORRHEA. Diplococcus gonorrhoeae,Gonococcus,Gonococcus neisseri,Merismopedia gonorrhoeae,Micrococcus der gonorrhoe,Micrococcus gonococcus,Micrococcus gonorrhoeae
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D015342 DNA Probes Species- or subspecies-specific DNA (including COMPLEMENTARY DNA; conserved genes, whole chromosomes, or whole genomes) used in hybridization studies in order to identify microorganisms, to measure DNA-DNA homologies, to group subspecies, etc. The DNA probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the DNA probe include the radioisotope labels 32P and 125I and the chemical label biotin. The use of DNA probes provides a specific, sensitive, rapid, and inexpensive replacement for cell culture techniques for diagnosing infections.
