Eight Neisseria gonorrhoeae isolates, negative by direct fluorescent antibody (DFA) but positive by a DNA probe, were characterized by pulsed field gel electrophoresis and compared to eight DFA-positive, probe-positive isolates. Results indicate that DFA-negative, probe-positive Neisseria gonorrhoeae isolates may be clonal.

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
D002999	Clone Cells	A group of genetically identical cells all descended from a single common ancestral cell by mitosis in eukaryotes or by binary fission in prokaryotes. Clone cells also include populations of recombinant DNA molecules all carrying the same inserted sequence.

D006069	Gonorrhea	Acute infectious disease characterized by primary invasion of the urogenital tract. The etiologic agent, NEISSERIA GONORRHOEAE, was isolated by Neisser in 1879.	Neisseria gonorrhoeae Infection
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
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.

D016521	Electrophoresis, Gel, Pulsed-Field	Gel electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length.
